Group of answer choices

Detecting a pain stimulus and sending a signal to the spinal cord to perform an automatic response

Producing an excessive amount of hormones in the blood and not sending a signal to stop production

Releasing insulin to decrease blood sugar and releasing glucagon to increase blood sugar

Using sense organs to get information about the outside world and direct an appropriate body response

Answers

Answer 1

Answer:Releasing insulin to decrease blood sugar and releasing glucagon to increase blood sugar

Explanation: homoestasis is the process by which the body keep it's internal environment constant, regardless of change in the external environment. The human body has a normal range in which it's system operates and it uses homoestasis to keep these at constant.

Homeostasis could be positive or negative. It usually involves a sensor which detects the changes in the body and passes the information to the control center, a control center which receive information from the sensor and sends signals to the effectors and the effector which acts on the information sent by the control center to effect normalcy.

In this case, when a person eats food,he gets glucose. Blood sugar most be kept at constant so the endocrine system release the hormone insulin. Insulin helps to convert glucose to glycogen, which is the form it can be stored in the liver

When the blood sugar levels is low, the brain which is the control center causes glucagon to be released . This hormone converts glycogen to glucose

Answer 2

Answers

Answer:

1.44 L

Explanation:

Since 25 is constant it is no use. Now, rearrange the gas formula. You should get...

P1V1/T2=P2V2T1

Next, rearrange to fit the problem. You should get...

V2=P1V1/P2

Fill in our values and solve. You should get 1.44 L

We can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.

The Ka for benzoic acid is 6.5 × 10−5. Calculate the pH of a 0.12 M benzoic acid solution.

Answers

Answer:

pH=4.05

Explanation:

C7H6O2  -> C7H6O-  + H+

ka= [C7H6O-] [H+]/[C7H6O2]

During equilibrium

[C7H6O-]= [H+]= x^2

[C7H6O2]=0.12-x

Replace

ka= x^2/0.12-x

6.5 x10^-5= x^2/0.12-x

7.8x10^-6 - 6.5 x10^-5x=x^2

x^2+ 6.5 x10^-5x - 7.8x10^-6

Solution of quadratic equation

x=8.8 x10^-5

pH= -log [H+]= -log 8.8 x10^-5=4.05

The pH value of the benzoic acid solution is equal to 4.05.

What is pH?

pH can be defined the negative logarithm of hydrogen ion concentration. pH can be seen as an abbreviation of the power of hydrogen or the concentration of hydrogen ions in a solution.

Mathematically, pH equals the negative logarithmic value of the concentration of hydrogen ion (H⁺).

pH = -log [H⁺]

The pH scale have range from 0 to 14 when 7.0 is neutral. A low pH is acidic and a high pH is basic. Pure water has a pH of 7.0.

The partial dissociation of benzoic acid in an aqueous solution can be shown as:

[tex]C_6H_5COOH +H_2O[/tex]  ⇄  [tex]C_6H_5COO^- +H_3O^+[/tex]

ka= [C₆H₅O⁻] [H₃O⁺]/[C₆H₅COOH]

At equlibrium:[C₆H₅O⁻] = [H₃O⁺] = x²

[C₆H₅COOH] = 0.12-x

The equilibrium constant: ka= x²/0.12-x

6.5 × 10⁻⁵ = x²/0.12-x

7.8 × 10⁻⁶- 6.5  × 10⁻⁵ x = x²

x²+  6.5  × 10⁻⁵ x- 7.8 × 10⁻⁶ = 0

The solution of the given quadratic equation will be:

x = 8.8 × 10⁻⁵

pH= -log [H⁺]= -log [8.8 × 10⁻⁵] =  4.05

Therefore, the pH of the given benzoic acid solution is 4.05.

If 23.6 grams of a substance reacts with 42.5 grams of another substance, what would we expect the mass of the products to be after the reaction?

Answers

Answer:

The correct answer is 66.1 g

Explanation:

According to Law of Conservation of the Mass, the mass of an isolated system is neither created or destroyed during chemical reactions. It is transformed. So, in a chemical reaction, the atoms of reactants are reoganizated by forming other compounds but the mass is conserved. Thus, the total mass of reactants is always equal to the total mass of products. If 23.6 g of a substance reacts with 42.5 g of another substance, the total mass of the products will be equal to the total mass of reactants:

23.6 g + 42.5 g = 66.1 g reactants = 66.1 g products

If a strong base, like NaOH, is added to a strong acid, like HCl, the pH of the resultant solution will _________. A.) Go up B.) Go down C.) Stay the same

Answers

Answer:

B.) Go down

Explanation:

Hello,

In this case, a strong base like NaOH has a high pH based on the scale wherein 7 is neutral, above 7 is basic and below 7 is acid. In such a way, by adding an acid, having a low pH, once it is added, the pH will go down until the equivalence point, which for strong base and strong acid should be 7.

Best regards.

Answer:

B) Go down

Explanation:

pH is defined as -log [H⁺], that means when concentration of H⁺ increases the pH decreases and when concentration of H⁺ decreases, pH increases.

When a strong acid as HCl is added to a solution, it is dissolved, thus:

HCl → H⁺ + Cl⁻

Thus, addition of a strong acid decreases pH because concentration of H⁺ increases.

Right answer is:

B) Go down

What’s the answer ?

Answers

Answer:

45.3°C

Explanation:

Step 1:

Data obtained from the question.

Initial pressure (P1) = 82KPa

Initial temperature (T1) = 26°C

Final pressure (P2) = 87.3KPa.

Final temperature (T2) =.?

Step 2:

Conversion of celsius temperature to Kelvin temperature.

This is illustrated below:

T(K) = T(°C) + 273

Initial temperature (T1) = 26°C

Initial temperature (T1) = 26°C + 273 = 299K.

Step 3:

Determination of the new temperature of the gas. This can be obtained as follow:

P1/T1 = P2/T2

82/299 = 87.3/T2

Cross multiply to express in linear form

82 x T2 = 299 x 87.3

Divide both side by 82

T2 = (299 x 87.3) /82

T2 = 318.3K

Step 4:

Conversion of 318.3K to celsius temperature. This is illustrated below:

T(°C) = T(K) – 273

T(K) = 318.3K

T(°C) = 318.3 – 273

T(°C) = 45.3°C.

Therefore, the new temperature of the gas in th tire is 45.3°C

How much H2 is generated from the electrolysis of 150 grams of H2O

Answers

Answer:

16.67 grams  of  H₂ is generated from the electrolysis of 150 grams of H₂O

Explanation:

Electrolysis is the decomposition of a chemical element under the effect of an electric current. So, electrolysis of water is the process of decomposing the H₂O molecule into separate oxygen and hydrogen gases due to an electric current passing through the water.

The balanced equation of electrolysis of water is:

2 H₂O → O₂ + 2H₂

Being:

H: 1 g/moleO: 16 g/mole

then the molar mass of the compounds that participate in the reaction is:

H₂O: 2*1 g/mole + 16 g/mole= 18 g/moleH₂: 2*1 g/mole= 2 g/moleO₂: 2*16 g/mole= 32 g/mole

If the following amounts in moles are reacted by stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction):

H₂O: 2 molesH₂: 2 molesO₂: 1 mole

the amount of mass, by stoichiometry, that reacts and is produced is:

H₂O: 2 moles*18 g/mole=36 gH₂: 2 moles* 2 g/mole= 4 gO₂: 1 mole* 32 g/mole= 32  g

Then you can apply the following rule of three: if by stoichiometry 36 g of H₂O generate 4 g of H₂, 150 g of H₂O how much mass of H₂ will it generate?

[tex]massofH_{2} =\frac{150 grams of H_{2}O*4 grams ofH_{2} }{36 grams of H_{2}O}[/tex]

mass of H₂= 16.67 grams

16.67 grams  of  H₂ is generated from the electrolysis of 150 grams of H₂O

Calculate the hyrdrogen ion concentration [h+] for the aquesous solution in which [oh-] is 1 x 10-2 mol/l.Is the solution acidic,basic,or neutral? Show your work

Answers

Answer:

- [tex][H^+]=1x10^{-12}[/tex]

- Basic.

Explanation:

Hello,

In this case, given the concentration of hydroxyl ions, one could compute the pOH as shown below:

[tex]pOH=-log([OH^-])=pOH=-log(1x10^{-2})=2[/tex]

Then, since the pOH and the pH are related by:

[tex]pH+pOH=14[/tex]

One computes the pH:

[tex]pH=14-pOH=14-2=12[/tex]

Now, we compute the concentration of hydronium by:

[tex][H^+]=10^{-pH}=10^{-12}[/tex]

[tex][H^+]=1x10^{-12}[/tex]

Finally, since the pH is greater than 7 (neutral point) we conclude that the solution is basic.

Best regards.

Answer:

A. Hydrogen ion concentration, [H+] is 1x10^–12 mol/L

B. Since the pH is 12, the solution is basic.

Explanation:

Data obtained from the question. This includes the following:

Concentration of Hydroxide ion, [OH-] = 1x10^–2 mol/L

Concentration of Hydrogen ion, [H+] =.?

pH =..?

A. Determination of the hydrogen ion concentration, [H+] .

The hydrogen ion concentration, [H+] can be obtained as follow:

[H+] x [OH-] = 1x10^–14

[OH-] = 1x10^–2

[H+] x 1x10^–2 = 1x10^–14

Divide both side by 1x10^–2

[H+] = 1x10^–14 / 1x10^–2

[H+] = 1x10^–12 mol/L

B. Determination of the pH of the solution.

The pH of the solution can be obtained as follow:

pH = –Log [H+]

[H+] = 1x10^–12 mol/L

pH = –Log 1x10^–12

pH = 12.

Then pH of a solution ranges between 0 and 14.

A pH reading between 0 and 6 is termed an acidic solution, a pH reading of 7 is termed a neutral solution and a pH reading between 8 and 14 indicates an alkaline or a basic solution.

The higher the pH value, the more alkaline or basic the solution becomes.

Since the pH is 12, the solution is basic.

how many number of electrons are in nitrogen and aluminium in their ionic States?​

Answers

If you look at the periodic table you’ll noticed a trend. Group one, sometimes called 1A, has hydrogen in it, it’s group (column) has a positive charge. The group (column) next to it Group 2 sometimes called 2A has twice the charge as group 1. Then you skip the transition metals, and then land on group (column) 13. These guys have a charge of +3 typically. Then you have group 14, sometimes called 4A, and it’s weird and it kind of breaks with this trend. Then you have group (column) 15 next to it, sometime called 5A, which now starts to count down in charge, it has a charge of -3.

And each group (column) after that countdown to zero charge, once you have zero charge you know that you’re in the noble gases.

So, nitrogen in group (column) 15, also know as column 5A. This column has for the most part a charge of -3.

Aluminum is in group (column) 13, they have a charge of +3 typically.
