Answer:
A
Explanation:
Hydrogen and chlorine need to be balanced. There is an equal amount of magnesium on each side
Answer:
Which class r u in hmm ? Tell me okay
In balancing nuclear decay types of reaction, the same as balancing a chemical reaction, we use the number and the type of nucleons present for the decay reaction. Regardless of the type of decay, it should be that the total number of nucleons in the shole process should be conserved. For carbon-11, the decay equation would be as follows:
11/6 C --->11/5 B + 0/1β
It is an example of a positron emmision or a positive beta decay. It is a decay for neutron-poor nuclei where a proton is being transformed into a neutron and also emitting a positron that is high in energy.
The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms

Explanation:
Hello there!
In this case, according to the solubility equilibrium of calcium hydroxide:
Whereas the equilibrium expression is:
![Ksp=[Ca^{2+}][OH^-]^2](https://tex.z-dn.net/?f=Ksp%3D%5BCa%5E%7B2%2B%7D%5D%5BOH%5E-%5D%5E2)
It is firstly necessary to calculate the molar solubility given the grams and volume of the dissolved solute:
Now, according to the Ksp expression, we plug in s as the solubility to obtain:
