The answer is D. easier, higher
With N2O4's molar mass of 92 grams/mole, there is 1 mole of N2O4 being used.
For every one mole of N2O4 used, two moles of N2H4 are used.
2 moles of N2H4 times the molar mass of N2H4 (32g/mol)
2 moles * (32 grams/mole) = 64 grams
Answer:
The volume of reactant measured at STP left over is 409.9 L
Explanation:
The temperature change on a 150g sample of mercury with specific heat of 0.0330 Cag°C, If 480 cal of heat is added to it is 96.9°C.
<h3>How to calculate temperature change?</h3>
The temperature change of a substance can be calculated using the following formula:
Q = m × c × ∆T
Where;
- Q = quantity of heat absorbed or released
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
480 = 150 × 0.033 × ∆T
480 = 4.95∆T
∆T = 96.9°C.
Therefore, the temperature change on a 150g sample of mercury with specific heat of 0.0330 Cag°C, If 480 cal of heat is added to it is 96.9°C.
