Answer:

heat = 229139.43 cal

Explanation:

given data

specific heat of iron is 0.107 cal/g-°C     C = 0.4494 J/g°C;

Mass of iron = 24.7 kg = 24700 g

temperature T1 = 880°C

temperature T2 = 13°C

solution

we know that Heat lost that is express as

heat loss = mcΔT      .........................1

here m is the mass and c is specific heat capacity of iron and ΔT is the change in temperature

so here change in the temperature is = 880°C - 13°C

change in the temperature = 867°C

so put here value and we get

heat  = 24700 × 0.107 cal/g-°C × 867°C

heat = 229139.43 cal

Answer:

Explanation:

Hb(CO)4(aq) + 4O2(g)  ⇄  Hb(O2)4(aq) + 4CO(g)

1 )  If we increase the concentration of CO(g) , the reaction above will proceed in reverse direction to decrease its concentration,  according to Le Chatelier principle. Hence more of Hb(CO)4(aq) will be formed.

2 )  If we decrease the concentration of O₂ , then also , reaction will proceed in reverse direction . Hence concentration of Hb(CO)4(aq) will be increased .

1. The Nummber of electrons present in the outermost shell is called Valence electrons.

2. Thomson model:

Thomson model of atom is the model which states that electrons are embedded in a positively charged solid material which is spherical in shape.

Rutherford model

Rutherford model of atom is the model which explains that there is a nucleus in the center of the atom and electrons are located around the nucleus.

3. Relative atomic mass. Atoms have very little mass , so they're difficult to measure accurately. Instead, chemists use a scale. On this scale the mass of a 12C atom is exactly 12.

4. Difference between Alpha, Beta and Gamma radioactive decay:

Alpha decay forms new element with two fewer protons and two fewer neutrons;

Beta decay forms new element with one more proton and one fewer neutron.

Gamma decay forms NO new element, but now the element has less energy because energy is released as gamma rays.

Gamma radiation has the highest penetration power, Beta decay goes the second, alpha decay the last. However, alpha particles make the most damage even if it has the lowest penetration power among the three.

5. This species has a 2− charge on it, so it is an anion. Anions are named using the stem of the element name with the suffix -ide added. This is the oxide anion.

Answer:

Explanation:

Answer:

C) indicator like cabbage juice

Explanation:

This is because the pH scale is used to show how acidic or alkaline a substance is. Also it can not be a and b as the sentence doesn't specify the pH nor if it is an acid or a base. This would mean that the sentence would not make sense with a&b.

The pH scale is a scale ranging from 0-14, with 7 being neutral and a number above 7 would be considered alkaline and if the number is less than 7 then it would be considered an acid.

Examples of indicators for the pH scale:

pH probe = a pH probe is a device used to show the pH of a substance.

Universal Indicator= a universal indicator is a substance that changes colour when exposed to a substance. Universal indicator can also show how acidic or alkaline a substance is.

Answer:

the pressure will decrease

Explanation:

Ideal gas law is valid only for ideal gas not for vanderwaal gas. The pressure will remain same as the initial pressure on decreasing volume and temperature by half.

Ideal gas equation is the mathematical expression that relates pressure volume and temperature. real gas can become ideal gas at low pressure and high temperature.

Mathematically the relation between Pressure, volume and temperature can be given as

PV=nRT

where,

P = pressure of  gas

V= volume of  gas =1/2V

n =number of moles of  gas

T =temperature of  gas =T/2

R = Gas constant = 0.0821 L.atm/K.mol

Substituting all the given values we get

P×(V/2)=nR(T/2)

(PV)/2=(nRT)/2

PV=nRT

Therefore, the pressure will remain same as the initial pressure  on decreasing volume and temperature by half.

Answer:

I need the things after "which of the following would occur".

Explanation:

If you were to maintain a constant volume while decreasing pressure, the temperature would also have to decrease. This is Boyle's law.

Answer: The amount of reactant doesn't really affect the rate of reaction, but the concentration does.

In order for there to be a reaction there has to be collisions between molecules, but only a fraction of these collisions are successful. The molecules have to be moving with enough energy, called the activation energy, to break the bonds between atoms. If there is a higher concentration of a solution, there are more molecules present per unit volume. This means that there will be more collisions and therefore more successful collisions, increasing the rate of reaction.

Answer: Option 4) is correct.

Explanation: It is correct because alkanes have a general formula CnH2n+2. So, all we need to do is substitute and find out how many hydrogens are needed to make the formula an alkane. I am not really good at explaining. I am sorry If I confused you.

Alkanes are the organic compound which has general formula [tex]C_{n}H_{2n +2}[/tex] which satisfies the formula [tex]C_{3}H_{8}[/tex]. Hence [tex]C_{3}H_{8}[/tex] represents an alkane.

Alkanes are simplest saturated hydrocarbon. Alkanes are also known as paraffins wax. Alkanes which contains only carbon and hydrogen atoms.

The general formula of alkane is [tex]C_{n} H_{2n + 2}[/tex] where n = 1, 2, 3, 4.......  

Thus, from the above conclusion we can see that option 4 [tex]C_{3}H_{8}[/tex] represents an alkane.

Sediment, sedimentary rock, or metamorphic rock are the parts of the rock cycle. Therefore, the correct option is option A.

Sedimentary rocks are created by the aggregation or deposition of organic or mineral particles at the Earth's surface, following by cementation. Sedimentation refers to the mechanisms that lead these grains to settle in situ.

Any of a family of rocks formed by the modification of pre - existing rocks in reaction to changing environmental circumstances, such as temperature, pressure, or mechanical stress, as well as the addition or deletion of chemical components is  metamorphic rock.

Hey there!

P₄ + Cl₂ → PCl₃

First, let's balance Cl.

There are 2 on the left, and 3 on the right.

To balance this, let's put a coefficient of 3 in front of Cl₂ and a coefficient of 2 in front of PCl₃.

P₄ + 3Cl₂ → 2PCl₃

Now we have 6 on the left and 6 on the right.

Next, let's balance P.

There are 4 on the left and 2 on the right.

Let's change the coefficient in front of PCl₃ from 2 to 4.

P₄ + 3Cl₂ → 4PCl₃

There are now 4 P on each side.

However, now Cl is unbalanced, with 6 on the left and 12 on the right.

We can change the coefficient in front of Cl₂ from 3 to 6.

P₄ + 6Cl₂ → 4PCl₃

So now, we have 4 P on each side and 12 C on each side.

This is our final balanced equation.

Answer:

The equilibrium concentration of gas A is 1.43 M

Explanation:

Here we have the reaction expressed as follows;

A + B → C + D and

The formula for equilibrium constant is therefore presented as follows;

[tex]K = \frac{[C]\times [D]}{[A]\times [B]}[/tex]

Where:

[C] = [D] = 2.3 M

[A] = [B]

K = 2.6

Hence, we have;

[tex]2.6 = \frac{2.3\times 2.3}{[A]\times [A]} = \frac{5.29}{[A]^2}[/tex]

[tex][A]^2= \frac{5.29}{2.6} = 2.03[/tex]

[A] = 1.43 M

The equilibrium concentration of gas A = 1.43 M.

Answer:

The equilibrium concentration of gas A = 1.43 M

Explanation:

First set up the equilibrium expression:

[tex]K = \frac{[C]\times [D]}{[A]\times [B]}[/tex]

The problem states that each product has a concentration of 2.3M at equilibrium, and that k=2.6

We also know that [A] and [B] are the same.

Since we are solving for [A] I'm going to change [A][B] to A²

[tex]2.6 =\frac{2.3^2}{A^2}[/tex]

Now we just need to solve for A²

A² = 5.29 / 2.6

A² = 2.0346

A = √2.0346

A = 1.43

Therefore, the equilibrium concentration of gas A = 1.43 M.

Answer:

55×10^-26 J

Explanation:

We can calculate the energy of the wave from

E= hc/λ

Where

h= Planks constant = 6.6×10^-34 Is

c= speed of light = 3×10^8 ms-1

λ= wavelength of the wave = 0.36 metres

Recall that cell phone use radio waves which belong to the electromagnetic spectrum hence it must possess the speed of light.

E= 6.6×10^-34 × 3×10^8/ 0.36

E= 55×10^-26 J

Hence the energy possessed by 0.36 meters wavelength radio waves is 55×10^-26 J
