Answer:
??? why did you add hehehehe?
Explanation:
If the balanced equation reads:
2N2 + O2 ———> 2N2O
You should have 1.72 moles of N2.

Answer:
Option e is correct
The heat required to increase the temperature of copper metal by 1 degree is 0.754 j
.
Explanation:
Given data:
specific heat of copper = 0.377 j/g.°C
Heat required to increase temperature = ?
Mass of copper = 2.00 g
Change in temperature = 1°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Q = m.c. ΔT
Q = 2 g× 0.377 j/g.°C × 1°C
Q = 0.754 j
The heat required to increase the temperature of copper metal by 1 degree is 0.754 j
.
