Answer:
The color black absorbs most colors, while white reflects most colors.
Answer:
Group 5th A.
Explanation:
The elements of group 5th A shows the electronic configuration of s² p³.
This group consist of nitrogen, phosphorus, arsenic, antimony, bismuth.
Electronic configuration of nitrogen:
N₇ = [He] 2s² 2p³
Electronic configuration of phosphorus
P₁₅ = [Ne] 3s² 3p³
Electronic configuration of arsenic
As₃₃ = [Ar] 3d¹⁰ 4s² 4p³
Electronic configuration of antimony
Sb₅₁ = [Kr] 4d¹⁰ 5s² 5p³
Electronic configuration of bismuth
Bi₈₃ = [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p³

Answer:
2 Al(s) + 3 CuSO₄(aq) ⇒ 3 Cu(s) + Al₂(SO₄)₃(aq)
Explanation:
Let's consider the single displacement reaction of Al(s) with CuSO₄(aq). Copper has a higher reduction potential than aluminum, so aluminum will take the place of copper to form aluminum sulfate and metallic copper. The corresponding balanced chemical equation is:
2 Al(s) + 3 CuSO₄(aq) ⇒ 3 Cu(s) + Al₂(SO₄)₃(aq)
Biology. I believe Ecology is the study of the ecosystem. Paleontology is the study of dinosaurs and Botany is the study of plants, which al deals with the study of life
