<h2>Answer:</h2>
<em><u>The kinetic energy of the air molecules in the cave is less than the kinetic energy of molecules outside the cave.</u></em>
<h3>Explanation:</h3>
The kinetic energy of any molecule is directly proportional to the temperature of the gas.
Temperature of a gas is the heat energy provided to the molecules. As the temperature energy increase the molecules of the gas will move fastly and collide with each other.
So we can know the kinetic energy of molecules in the gas by measuring its temperature.
Hence the temperature of the cave is less than outside, so the kinetic energy will also be low.
You got it, reactant must collide in proper orientation and with enough energy. Imagine you double concentration, you are doubling the amount of reactant thus giving more collision at the molecular level thus increasing the reaction rate.

Answer:
8.88 grams of aluminum nitrate should be weighted.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to use the definition of molarity to calculate the moles of aluminum nitrate as follows:

Now, since the molar mass of aluminum nitrate is 212.996 g/mol, we obtain the following mass:

Therefore, 8.88 grams of aluminum nitrate should be weighted.
Regards!
Answer:
Liquid : A liquid has definite mass and it's volume does not change. It is hard to compress but flows easily. The shape of the liquid varies and depends on then shape of the container holding it.
Solid : A solid has a definite mass, definite shape and it's volume does not change. It does not flow and it is hard to compress.
Gas : A gas has a definite mass but it's volume can vary and it takes up the shape of container holding it. It flows easily and it is easy to compress.
