Answer
D. The gas molecules in both containers have the same average kinetic energy.
Explanation:
I don't know where the question is, but I will assume that this is a True or False statement.
If that is the case, this statement is false.
You have the equation Q = mc<span>ΔT.
The statement states that if m is doubled, c is doubled as well. This is incorrect, since the specific heat value cannot be changed because it is attributed to the specific substance. If m doubles with the same substance, assuming a constant change in temperature, the only thing that can change is Q, which is the heat energy gained or lost from the substance.</span>
Yes, if we're talking about intramolecular bonds
Answer:
3
Explanation:
A cyclic event is one that happens repeatedly.
The appearance of Hailey's Comet is a cyclic event because it has happened in various occasions in the past on a regular schedule as predicted. We have every reason to believe that the appearance of Hailey's Comet every 75 years will continue to be happen until the comet ceases to exist.
The moles of product are formed is 0.0303 mol
The process we are interested in is
3Mg + N2 to Mg3N2.
N(Mg3N2) = n(Mg)/3 = 0.0303 mol moles of product were produced.
<h3>What is Moles ?</h3>
A mole is the mass of a substance that includes 6.023 x 10^23 of that substance's particles. The mole is the SI unit used to measure a substance's quantity. It has the symbol mol. As a result: One mole of carbon-12 weighs 12 grammes and has a carbon atom content of 6.022140857 x 10^23.
- In particular, in terms of mass, it serves as a bridge between the microscopic and the macroscopic. A unit (atom or molecules) has the same mass in grammes as a mole of a substance has in atomic mass units.
Hence, moles of product are formed is 0.0303 mol
