In general, solubility increases with temperature. When you increase the temperature of a solvent, you increase the kinetic energy (or energy of movement) of the molecules, and this greater energy helps dissolve more of the solute molecules.
Answer:224
Explanation:
We should answer it with Stoichiometry
We say: 20 g H2× (1 mol/ 2g)× ( 22.4 lit/ 1 mol) = 224
Means: we have 20 grams and every 2g H2, equals to 1 mol of it and every 1 mol of H2, equals to 22.4 lit( because of STP)

The compound FeCl3 is made of one atom and three atoms of chlorine
<u><em>explanation</em></u>
- FeCl3 is made up of two elements.
- that is iron with Fe chemical symbol and chlorine with Cl chemical symbol.
- There are 3 atoms of chlorine in FeCl3 because the subscript in front of Cl in FeCl3 is 3.
Answer is: It has a negative charge and is located in orbitals around the nucleus.
The electron (symbol: e⁻) is a subatomic particle whose electric charge is negative one elementary charge.
Electrons are moving in energy levels around nucleus.
The electron has a mass that is approximately 1/1836 that of the proton.
Electrons have properties of both particles and waves.
The correct answer is c because enzymes increase the rate of all biochemical processes
