You need .556M HCL to neutralize that
Answer:

Explanation:
First of all we need to calculate the heat that the water in the cooler is able to release:

Where:
- Cp is the mass heat capacity of water
- V is the volume
is the density


To calculate the mass of CO2 that sublimes:

Knowing that the enthalpy of sublimation for the CO2 is: 


Mutual
They are balanced steadily which means they’re at the same point
Answer:
Homogeneous - With a uniform appearance
Heterogeneous - With visible differences in the mixture
