Since particles are closer together, solids conduct heat better than liquids or gases. Conduction moves heat through a material. It keeps a fire going by spreading the heat through solid material. Radiation is a method of heat transfer that does not require particles to carry the heat energy.
Answer: C, 146
Explanation:
NaCl has a molar mass of 58.44 g/mol.
To change moles to g, we do:
2.50 moles × 58.44 g/mol = 146.1 g, so C
Answer:
Thus, as both an amphoteric compound and the most common liquid on Earth, it follows that water is both the most common acid as well as the most common base on planet Earth
Answer : The partial pressure of the 
in the tank in psia is, 32.6 psia.
Explanation :
As we are given 75 % and 25 % 
in terms of volume.
First we have to calculate the moles of and .
Now we have to calculate the mole fraction of .
Now we have to calculate the partial pressure of the gas.
conversion used : (1 Kpa = 0.145 psia)
Therefore, the partial pressure of the in the tank in psia is, 32.6 psia.
