The heat lost by copper(ii) sulfate is equal to heat absorbed by water since the total energy in the system remains constant according to the law of conservation of energy.
<h3>How can the number of moles be determined?</h3>
The number of moles of a substance is determined using the formula below:
- Number of moles = mass/molar mass
Assuming the mass of copper(ii) sulfate used is <em>Mc</em>, number of moles of copper(ii) sulfate used is:
- Moles of copper(ii) sulfate = <em>Mc</em>/159.60 moles
The heat absorbed by water is calculated using the formula below:
- Quantity of Heat, H = mass × specific heat capacity × temperature change
mass of water <em>=</em><em> </em> 10 g
Let temperature change be <em>Tc</em>
Heat<em> </em>absorbed<em> </em>by water = 10 × 4.186 × Tc = 41
86Tc
The change in internal energy, ΔU of copper(ii) sulfate, is given as:
where:
Q = heat absorbed by water
W = work done by or on the system
The enthalpy of the reaction is given as:
- ΔH= energy released or absorbed/moles of copper (ii) sulfate
Therefore, according to the law of conservation of energy, the total energy in the system remains constant.

I believe a. is the answer.
Answer:
44 Grams of CO2 will be generated
Explanation:
Balanced equation:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)
1mol CH4 reacts with 2 mol O2 to produce 1 mol CO2
Molar mass O2 = 32g/mol
Molar mass CH4 = 16g/mol
Molar mass CO2 = 44g/mol
A solution is a when a solvent is mixed completely with a liquid. it would be a homogeneous mixture because it is mixed together and you can not separate it.
