Answer:
b Fuel for fusion reactors can be extracted from ocean water.
Explanation:
The fuel is deuterium, which makes up 0.02% of the hydrogen atoms in water. The oceans contain more than a billion cubic kilometres of water, so that's a lot of deuterium.
a is wrong. The fuel for fusion reactors is deuterium.
c is wrong. There is much research, but there are no large-scale fusion reactors in operation.
d is wrong. Fusion reactors do not produce radioactive waste as spent fuel. Most of the radioactive waste would be the reactor core itself.
Answer:process of using an electrical current to separate water into hydrogen and oxygen gas
Explanation:
Three examples of environmental, industrial and bio-chemistry are listed below:
- Environmental chemistry: Contamination, Atmospheric Deposition, and Soil Pollution.
- industrial chemistry: industrial inorganic chemicals, industrial organic chemicals, and agricultural chemicals
- bio-chemistry: genetic, immunology, and enzymology
<h3>Meaning of Chemistry</h3>
Chemistry can be defined as a branch of science which is concerned with the substances matter is composed of, their properties and reactions,
Chemistry also deals with the use of such reactions to form new substances.

Answer:
a. 102.6g/mol
b. Rb⁺
Explanation:
a. The unknown base, XOH, <em>Where X is the alkali metal</em>, reacts with HCl thus:
XOH + HCl → H₂O + XCl
<em>Where 1 mole of the hydroxide reacts per mole of acid. </em>
Moles of HCl spent to reach the equivalence point are:
17.0mL = 0.017L ₓ (2.50mol / L) = 0.0425moles of HCl
As 1 mole of HCl reacts with 1 mole of base, moles of base are 0.0425 moles.
Molar mass of a compound is the ratio between mass in grams and moles of substance, that is:
4.36g / 0.0425mol =
<h3>102.6g/mol</h3>
b) Molar mass of OH is 17g/mol, thus, the molar mass of the alkali metal is:
102.6g/mol - 17g/mol = 85.6g/mol
The mass of Rb is 85.5g/mol, thus, the identity of the alkali metal is
<h3>Rb⁺</h3>
