Explanation:
pressure, volume, temperature, and the number of moles, it was clear that a single. atm of pressure within safety limits, how much gas can it safely carry at room. 0.21 atm. Ar has a partial pressure of 0.01 atm. PN2 .78 atm 0.78 moles nN2.
Answer:
Final temperature =78°C
Explanation:
The amount of heat lost is calculated using the formula for calculating the enthalpy change: mCΔT C, the specific heat capacity for for water is 4.186J/gK. The mass of water is 30 grams.
1500J= 30g×4.186J/gK×ΔT
ΔT=1500J/(30×4.186J/gK)
=11.94K
final temperature=(90-12)°C
=78°C
I think 4 is a but not positive if it is.
<span>I would say : B ) Equilibrium always happens at the same point in the reaction no matter where you start.
