Answer:
This would be a phase change
Explanation:
Since the diffrent phases solid,liquid,gas are changing to other phases.
Sorry for the bad explanation.
The term formula units means molecules.
Then, what you are looking for is the mass in 4.59*10^24 molecules.
The procedure involves to convert the 4.59 * 10^24 molecules into moles and use the molar mass of the sodium chloride.
1) Number of moles = 4.59 * 10^24 molecules / (6.02 * 10^23 molecules/mol) = 7.62 mol
2) Molar mass of NaCl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol
3) mass of NaCl = molar mass * number of moles = 58.44 g/mol * 7.62 mol = 445.31 g of NaCl
Answer: 445.31 g of NaCl.
The speed limit would be 70.2 mi/h
B. Low; very little
Explanation:
Metals such as iron, lead, copper and zinc have low specific heats. This means that it takes very little energy to change their temperature.
Specific heat is the heat required to raise the temperature of 1g of substance by 1°C.
Metals have good thermal conductivity and generally have low specific heat. This implies that their temperature can easily be raised when heated.
Some substances like water have very high specific heat. This suggests that they require more heat to raise their temperature.
