Mike watch 100 m north then watch 30 m south after this he walks another 10 m north what is the magnitude of his total displacement during this walk in meters

Answers

Answer:

His total displacement is 80 m northwards

Explanation:

Given;

Mike's first displacement, x₁ = 100 m North

Mike's second displacement, x₂ = 30 m South

Mike's third displacement, x₃ = 10 m North

Let his Northwards direction be positive, and

his Southwards direction be negative

His total displacement = (100 m North) + ( - 30 m South) + (10 m north)

                                     = (100 m + 10m - 30 m)

                                     = 80 m  Northwards

Gallium has two natural occuring isotopes: Ga-69 with 68.9256 amu and a natural abundance of 60.11%, and Ga-71 with mass 70.9247 amu and a natural abundance of 39.8%. Calculate the atomic mass of gallium.

Answers

To calculate the atomic mass, add each amu multiplied by its relative abundance and divide it all by 100

Ar (Ga) = (68.9256x60.11) + (70.9247x39.8)
/100

= 4,143.12 + 2,822.80 /100

= 69.66

Arrange Cu, Ca, Na, Zn and Au on the basis of their decreasing reactivity.​

Answers

Answer:

1. Sodium (Na) is the most reactive due to its lower number of shells which enables the protons in it's nucleus to attract more electrons.

2. Calcium (Ca) is next as it is a group 2 element and they can be quite reactive.

3. Zinc (Zn) is the third reactive as transition metals are not very reactive.

4. Copper (Cu) is less reactive than Zinc because it is closer to the center of the periodic table and therefore has more stability.

5. Gold (Au) is the least reactive.

How would you go about calculating the molarity of the following solution: 19.5 grams of Be(OH)2 is dissolved in enough water to make a 1.5 L solution.

Answers

Answer:

0.302M

Explanation:

Molarity, which is the molar concentration of a solution can be calculated as follows:

Molarity = number of moles (n) ÷ volume (V)

According to this question, 19.5 grams of Be(OH)2 is dissolved in enough water to make a 1.5 L solution.

Using mole = mass/molar mass to calculate the number of moles in 19.5g of Be(OH)2

Molar mass of Be(OH)2 = 9 + (16 + 1)2

= 9 + (17)2

= 9 + 34

= 43g/mol

mole = 19.5/43

mole = 0.453moles

Molarity = n/V

Molarity = 0.453/1.5

Molarity = 0.302M

Below are descriptions of different center voids of a solid fuel. Which design

Answers

B. A circle.

The center void shape that generates the most thrust in a solid fuel rocket is a circle.

What is Fuel?

Fuel is a substance that is used to produce heat or energy through combustion or other chemical reactions. It can be in the form of a solid, liquid, or gas and is typically used to power engines, generators, or heating systems. Examples of fuels include gasoline, diesel, natural gas, coal, wood, and propane. The choice of fuel depends on factors such as availability, cost, energy content, and environmental impact.

This is because a circular shape allows for the most efficient burning of the fuel, with the flame front moving evenly in all directions. Other shapes, such as a heart, triangle, or tree with branches, can cause uneven burning and may result in less thrust.

If 14.7 cm3 of alcohol is present in 70 cm 3 of its aqueous solution, the percentage by volume of alcohol will be?

Answers

Answer: The percentage by volume of alcohol will be 21%.

Explanation:

Given: Volume of solute = 14.7 [tex]cm^{3}[/tex]

Volume of solvent = 70 [tex]cm^{3}[/tex]

Formula used to calculate percentage by volume is as follows.

[tex]Percentage volume = \frac{volume of solute}{volume of solvent} \times 100[/tex]

Substitute the values into above formula as follows.

[tex]Percentage volume = \frac{volume of solute}{volume of solvent} \times 100\\= \frac{14.7 cm^{3}}{70 cm^{3}} \times 100\\= 21 percent[/tex]

Thus, we can conclude that the percentage by volume of alcohol will be 21%.

A. At equilibrium
B. Spontaneous
C. Nonspontaneous
D. Not at equilibrium

Answers

Answer:

B

Explanation:

Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. ... In this case, the products, or final state, have more free energy than the reactants, or initial state. Endergonic reactions are non-spontaneous, meaning that energy must be added before they can proceed.

Exergonic reactions were often known as spontaneous reaction. since they can take place without the expenditure of energy.

What is exergonic reactions?

A reaction wherein energy is emitted mostly in presence of light or heat was known as just an exothermic reaction.

What is spontaneous reaction?

A spontaneous process would be one that happens without the system receiving any outside input.

Because exergonic events could proceed without the supply of energy, they are sometimes known as spontaneous reactions. The products possess greater free energy as compared to  the reactants example. Endergonic reactions were non-spontaneous, which means they require the addition of energy before they can begin.

Why does it stop expanding when you stop blowing air into it

Answers

Answer:

this is because of collisions of molecules present in that particular system.

Explanation:

For instance, when air is filled in a balloon then the number of the molecules of air inside the balloon increases. As a result more collisions of molecules take place with the walls. This gives rise to high air pressure on the walls which causes the balloon to expand and get inflated.

A 15.8 g sample contains 3.60 g F, 4.90 g H, and 7.30 g C. What is the percent composition of hydrogen in this sample?

Answers

Answer: 22.7848% F or 23%

Explanation: %F = 3.6g/15.8g • 100% = 22.7848% F

The percentage composition of hydrogen in the given sample is equal to 31%.

What is percentage composition?

The percentage composition of a given compound can be described as the ratio of the quantity of each element to the total quantity of individual elements in the compound multiplied by 100. The quantity can be measured in terms of grams of the elements present in the sample.

The percent composition is expressed in its composition in terms of all the elements present. Thus, it helps in the chemical analysis of any given compound.

The percentage composition is expressed using the following formula,

Percentage composition of E = (E/T) × 100

Where E represents the total quantity of element E present in the compound and T represents the total quantity of all the elements present in the compound.

Given, the mass of the F, H, and C is 3.60g, 4,90 g, and 7.30 g respectively.

The total mass of the given sample = 15.8 g

The mass of the hydrogen in the sample = 4.90 g

The percent composition of H = (4.90/15.8) × 100 = 31 %

Therefore, the percent composition of hydrogen in this sample is 31%.
