Question

which of the following elements were formed during the big bang? (choose all that apply) lithium hydrogen beryllium boron helium the law of conservation of matter states matter is not created nor destroyed. true false what is the correct ratio of hydrogen to helium in the universe? equal parts or 1:1 1/4 hydrogen and 3/4 helium 1/4 helium and 3/4 hydrogen 2/4 hydrogen and 1/4 helium

Explanation:

• First question: During the Big Bang, light elements like hydrogen, helium, and trace amounts of lithium were formed. Beryllium and boron were not formed in significant amounts during the Big Bang.
• Second question: The law of conservation of matter states that matter is not created nor destroyed in a chemical reaction (in a closed system).
• Third question: The approximate ratio of hydrogen to helium in the universe is about 3/4 hydrogen and 1/4 helium by mass.

Answer:

• First question: Lithium, Hydrogen, Helium.
• Second question: True.
• Third question: 1/4 helium and 3/4 hydrogen.
