D.) Br
Explanation:
I don’t really have an explanation.
I hope this helps!
<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>
Answer:
grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
Explanation:
The molecular weight of acetylene is 26.04 g/mol
Molecular weight of carbon is equal to 12.011 g/mol
Two carbon atom produces one acetylene molecule.
Thus, 2 * 12.011 g/mol of carbon is used to produce 26.04 g/mol of acetylene,
Amount of carbon required to produce 59.8 grams of acetylene
grams/mol
grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
I believe the answer is Chlorophyll. During photosynthesis light energy from the sun is trapped by chlorophyll, it is then used to break down water molecules to hydrogen ions and oxygen gas. This represent the first stage of photosynthesis called light dependent stage. The hydrogen ions formed in this stage then joins the light independent stage (dark stage) and oxygen is released to the atmosphere or released to the atmosphere.
The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
