Answer:
Awnser: D,Newtons second law of motion
Answer:
a mole of calcium is 6.02 ×10²³, therefore 2.9 ×10²⁴ will be ~4.82moles,
And since a mole of calcium is 40.1g
4.82 moles will be 4.82 × 40.1
that's =193.28g
Answer:

Explanation:
Hello,
In this case, by using the general gas law, that allows us to understand the pressure-volume-temperature relationship as shown below:

Thus, solving for the temperature at the end (considering absolute units of Kelvin), we obtain:
