I believe it is because, Lead has a higher boiling point than zinc. by the time Lead melts and becomes a liquid, the temperature is way higher than the boiling point of Zinc therefore, Zinc becomes a gas.
Answer:
B) 2Crº + 6e- --> 2Cr3+
Explanation:
The process of oxidation is where electrons are lost. Thus, out of the 2 ions that change charge(Cr and Cu), we must choose the one where the oxidation number increases(which means electrons are lost). Cr goes from an oxidation number of 0 to an oxidation number of 3+, while Cu goes from an oxidation number of 2+ to 0. Thus, we are looking at the half reaction for Cr. Half reactions never have subtracting electrons, so the answer must be B. I am assuming that last plus should be a -->
The answer is <span>B. Fusion occurs inside the sun. It creates light and heart that sustain life on earth.
The Sun creates its own energy through fusion. This also happens in larger stars as well.

Answer:
A
C
Explanation:
For the reaction of m-bromonitrobenzene from benzene first, we need to carry out the nitration of benzene utilizing HNO3, H2SO4.
Bromination of nitrobenzene with Br2, FeBr3 outfits m-bromonitrobenzene in light of the fact that nitro group is meta coordinating for electrophile. The mechanism activity for the reaction is shown in the image below.
Answer:
Electrons
Explanation:
Atoms both have negative and positive particles
Protons are positive
Electrons are negative
Neutrons are neutral
Nuclei is where you find both neutrons and protons in an atom
