Answer:
Explanation:
Hello there!
In this case, according to the Gay-Lussac's gas law, which illustrates the pressure-temperature behavior as a directly proportional relationship:
We can solve for the final pressure as shown below:
Thus, we plug in the initial pressure and temperature and final temperature to obtain:
Which is not among the choices.

Answer:
Atoms: <em>they are tiny particles that are the basic building blocks of any substance. The atoms are themselves made up of even smaller particles-protons, neutrons and electrons. </em>
Molecules: <em>it is the smallest unit of matter, which can exist independently. A molecule is formed when two or more atoms combine together.</em>

Answer:
Br - C ≡ N
Explanation:
To draw the Lewis line-bond structure we need to bear in mind the octet rule, which states that in order to gain stability each <em>atom tends to share electrons until it has 8 electrons in its valence shell</em>.
- C has 4 e⁻ in its valence shell so it will form 4 covalent bonds.
- Br has 7 e⁻ in its valence shell so it will form 1 covalent bond.
- N has 5 e⁻ in its valence shell so it will form 3 covalent bonds.
The most stable structure that respects these premises is:
Br - C ≡ N
It does not have any H atom.
Answer:
0.16mole
Explanation:
To solve this problem, we are going to assume that the number of moles of carbon to be determined is that at STP, standard temperature and pressure.
The number of moles of a substance at STP is given as;
Number of moles = 
Given volume = 3.5L
Now, insert the parameters;
Number of moles = 
= 0.16mole
