Answer:
<h3>D energy of motion</h3>
Explanation:
Kinetic energy is the energy present in mass in motion
Answer:
Mass, m = 7.97 grams
Explanation:
We have,
Initial temperature was 34 degrees Celsius
Heat produced in it is 100 calories of heat
The specific heat capacity of water is 4.18 J/g °C
The heat produced due to change in temperature is given by :

m is mass of water in grams

So, 7.97 grams of water is required to produce heat of 2200 joules.
I will have to say that this statement is true
Answer:
Gas X
Explanation:
The given reaction can be written in the form of chemical equation as shown below as:

According to law of conservation of mass, the moles of each substance in the reaction must be equal on both reactant and product side.
Also, the question asks for the gas which is diatomic.
cannot be diatomic as the formula contains 3 atoms.
Between gas X and gas Y , <u>X has to be diatomic for the reaction to balance </u>as:

Well assuming we have all of these, earth
