The energy absorbed may be calculated using:
Q = mcΔT
Where Q is the energy absorbed, m is the mass of water, c is the specific heat capacity of the water and ΔT is the change is the temperature of the water. Substituting the values,
Q = (435)(4.18)(100-25)
Q = 136,372 J
The energy absorbed is 136.4 kJ
The answer should be (A) liquid to solid. This is because it releases the heat absorbed by it when it had changed into liquid.
Because energy need to be Times 4. Not sure if I helped you
Answer:
A reactant is a substance that is present at the start of a chemical reaction. A product is a substance that is present at the end of a chemical reaction.
Explanation:
Answer:
500 moles
Explanation:
Given mass of SO2 = 32
Molar mass of SO2 =64
So, 32x10^8/64=500
