Water can be formed in the following reaction:
andreev551 [17]

Answer is: 10 moles of water will be produced.

Balanced chemical reaction of formation of water:

2H₂ + O₂ → 2H₂O.

n(H₂) = 10 mol; amount of hydrogen gas.

From balanced chemical reaction: n(H₂) : n(H₂O) = 2 : 2 (1 : 1).

n(H₂O) = n(H₂).

n(H₂O) = 10 mol; amount of water.

How can helium exist in three different forms
saul85 [17]

Explanation:

Helium exists in three different forms due to the phenomenon of isotopy. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their nuclei.

  • The atoms of these elements are called isotopes.
  • This is why Helium can exist in three different forms.
  • Isotopes have the same electronic configuration but with the same chemical properties.

Explain how a pure metal is held together
Tom [10]
<span>Metallic bonds consist of the attraction of the free-floating valence electrons (negative) for the (positive) metal ions. These bonds are the force of attraction that hold metal together.A piece of pure metal, such as copper or iron, consists of metal atoms surrounded by mobile valence electrons that are free to drift from one part of the metal to another. Metallic bonds result from the attraction between the free-floating valence electrons and the positively charged metal ions.</span>

Where did the mass of the forest trees come from?
jenyasd209 [6]
The mass of a tree is primarily carbon. The carbon comes from carbon dioxide used during photosynthesis. During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water.
