Answer:

*a car geared neutral that is at a stop. two men start pushing it

*tire physical therapy. trie is at rest until you come up to the tire and flip it

*pushing a wheel barrel

Explanation:

everthing has to be at a complete stop then through energy be moved

At a given temperature, the elementary reaction A − ⇀ ↽ − B , in the forward direction, is first order in A with a rate constant

ZanzabumX [31]

Answer:

0.24

Explanation:

We are given that

Rate constant for A= $k=0.0180/s$

Rate constant for B,k'=0.0750/s

We have to find the value of equilibrium constant for the reaction

$A\rightleftharpoons B$

Equilibrium constant, for k= $\frac{k}{k'}$

Using the formula

$k=\frac{0.0180}{0.0750}=0.24$

Hence, the value of the equilibrium constant for the reaction

$A\rightleftharpoons B$ at this temperature=0.24

How does soil form from bare rock

Masteriza [31]

Weathering and erosion produce smaller rock particles which, when mixed with dust result in different types of soil.

A balloon has a volume of 3.50 liters at 20.0°C. What will be the volume of the balloon at 100.0°C? Assume the pressure doesn't

Nikitich [7]

<u>Answer:</u> The volume of balloon at 100°C is 4.46 L

<u>Explanation:</u>

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=3.50L\\T_1=20^oC=(20+273)K=293K\\V_2=?L\\T_2=100^oC=(100+273)K=373K$

Putting values in above equation, we get:

$\frac{3.5L}{293K}=\frac{V_2}{373K}\\\\V_2=4.46L$

Hence, the volume of balloon at 100°C is 4.46 L
