How much heat do you need to raise the temperature of 150 g of ice from -30°C to -15°c?
OLga [1]
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.

Given the reaction represented by the balanced equation:
user100 [1]

Answer:

mass of CHF_3 = 1/3 \times 9.47 \times 70 =220.97g

Explanation:

CH_4(g)+3F_2(g)->3HF(g)+CHF_3

As given in the question that methane(CH_4) is taken excess amount

mass of CHF_3 depend only on mass of fluorine

mass of F_2 =180 g

mole of F_2=\frac{180}{19} =9.47

3 mole of F_2 gives 1 mole of CHF_3

so 1 mole will give \frac{1}{3} mole of CHF_3

therefore,

9.47 mole of F_2 will give \frac{1}{3}  \times 9.47 mole of CHF_3

mass of CHF_3 = 1/3 \times 9.47 \times 70 =220.97g
