To solve this question, you must use the formula: q=mc(change in temperature), where q is heat, m is mass, C is specific heat and temperature change is temperature change. The specific heat for ice is 2.1kJ/Kg x K (given). The change in temperature is 15 degrees Celsius (which you should change to kelvins so you can cancel out units), or 273 + 15 = 288K. The mass is 150 grams, which is 0.15 kg. Now, we can solve for q, heat. We will do this by substituting variables into the formula. After simplifying and cancelling out units, the answer we get is: 90.72kJ.

Answer:

Explanation:

As given in the question that methane(
) is taken excess amount
mass of
depend only on mass of fluorine
mass of
=180 g
mole of
=
=9.47
3 mole of
gives 1 mole of 
so 1 mole will give
mole of 
therefore,
9.47 mole of
will give
mole of
