<h3>The temperature is 15.58 kelvin </h3>

<em><u>Solution:</u></em>

<em><u>Ideal gas equation is given as:</u></em>

PV = nRt

Where,

P = pressure

V = volume

n = amount of substance

R = ideal gas constant

T = temperature

From given,

V = 120 liters

n = 5 moles

R = 8.314\ \frac{Lkpa}{mol\  K}

P = 5.4 kPa

T = ?

Therefore,

5.4 \times 120 = 5 \times 8.314 \times T\\\\648 = 41.57 \times T\\\\T = 15.58\ kelvin

Thus the temperature is 15.58 kelvin

What does the law of conservation of energy impy
Rasek [7]
The law of conservation of energy is that energy cannot be created or destroyed, but it can be transferred or transformed from one form to another (including transformation into or from mass, as matter). The total amount of energy in a closed system never changes. energy in a system may be transformed so that it resides in a different state.

.One ballon is filled with Hydrogen (H2) gas, the other balloon is filled with methane (CH4). Both balloons have the same temper
Neko [114]

Answer:

C. The balloon with CH4 has the same moles of gas molecules as the balloon with H2

Explanation:

Based on combined gas law, gases under the same pressure, temperature and volume have the same number of moles. With this information we can say the rigth statement is:

<h3>C. The balloon with CH4 has the same moles of gas molecules as the balloon with H2</h3>

What is the relationship between mass and gravity
Tpy6a [65]

Answer:

since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

What is the effect of high activation energy on a chemical reaction?
alex41 [277]
<h3><u>Answer;</u></h3>

It makes the reaction harder to start

<h3><u>Explanation</u>;</h3>
  • <em><u>Activation energy is minimum amount of energy that is required for a reaction to start. Activation energy determines the rate of a chemical reaction such that the higher the activation energy, the lower the rate of chemical reaction and vice versa.</u></em>
  • The source of activation energy needed to push chemical reactions forward is obtained from the surroundings. Catalyst speed up chemical reaction by lowering the activation energy. Therefore, catalysis is the increase in the rate of a chemical reaction by lowering its activation energy.
