Answer:
It's C
Protons repel the neutrons.
Explanation:
An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. The instability of an atom's nucleus may result from an excess of either neutrons or protons.
0.1 mL of the stock solution of the enzyme is taken and made up to 5.0 mL with 0.001M HCl in order to prepare a 50-fold diluted enzyme.
<h3>What is dilution?</h3>
Dilution is a process of making a solution of lower concentration from a solution of higher concentration by the addition of solvent to a given volume of the solution of higher concentration.
Dilution of solutions is done using the dilution formula in order to determine the given volume of diluent or stock solution required. The dilution formula is given below:
where:
- C1 = Initial concentration of enzyme
- C2 = Final concentration of enzyme
- V1 = Initial volume
- V2 = Final volume
For the enzyme dilution;
C1 = 1 mg/mL
C2 = 1/50 mg/ml = 0.02 mg/ml
V= ?
V2 = 5 ml
V1 = C2V2/C1
V1 = 0.02 * 5/1 = 0.1 mL
Therefore, 0.1 mL of the stock solution of the enzyme is taken and made up to 5.0 mL with 0.001M HCl in order to prepare a 50-fold diluted enzyme.

Pretty sure it’s C the added products drives reverse reaction and since forward releases heat, reverse would absorb.
Explanation:
Pumice is an extrusive igneous rock that is produced through volcanic activities.
A rock like pumice will pass through the rock cycle and be transformed to other rock types with time.
Pumice contains rich mafic minerals giving it that black appearance.
The consequences of this is that when the rock is acted upon by weathering elements, it is weathered to clay. A fine grained sediment. It will eventually be transformed to shale or claystone sedimentary rocks.
If is goes through the metamorphic path, a schist will form under conditions of high pressure and temperature. New minerals will grow and metamorphic transformation would be vivid.
Eventually, both sedimentary and metamorphic rocks can be subducted and will form the original melt again.

Answer:
if speed or direction changes then there is a change in velocity which is acceleration. Hope this helps!
