Explanation:
atomic hydrogen torch utilizes an electric arc whereby two closely - but not touching electrodes - result in the release of powerful electric spark as the current tries to flow through the gap. The gap is filled with hydrogen gas in an atomic hydrogen torch rather than air. The electric arch is split the hydrogen gas molecules into hydrogen atoms (some in plasma form). When the hydrogen atoms land on cooler objects like the metal being welded or cut, they region back to H₂ molecules releasing enormous amounts of heat on the surface. Surface temperatures can reach 4000 °C. The use of hydrogen gas protects the metal being welded from oxidation. Oxidation may compromise the quality of the weld.

So, I don't know the answer for b but I think I found the answer for a.
I sincerely hope this isn't wrong
Answer:
Carbon dioxide is a chemical compound composed two oxygen atoms covalently bonded to one carbon atom. Carbon dioxide's molecular shape is linear. Also carbon dioxide exists in Earth's atmosphere as a gas. Carbon Dioxide- CO2 makes up one of the gases in our atmosphere.

Explanation:
1. Cross-pollination between true-breeding plant with green pods and true-breeding plant with yellow pods.
2.The yellow pods do not appear because the heterozygous dominant for the green pods. So the green is dominant while the yellow is recessive. So the green is what comes out has the result..
