B. Lemonade, it's a mixture of sugar, lemon juice, and water
The two atoms shown in the equation are CALCIUM and oxygen.
<span>You start off with a neutral calcium atom with a shell of two electrons, a shell of 8 around that, a shell of 8 around that, and a shell containing 2...with no charge. </span>
<span>20 protons + 20 electrons. </span>
<span>You also have an oxygen atom with a shell of 2, and a shell of 6...with no charge. </span>
<span>8 protons + 8 electrons. </span>
<span>Each ionizes to form a calcium ion with 2 electrons removed (from the outer shell), leaving a +2 charge (20 protons, 18 electrons)... </span>
<span>and an oxygen ion with 2 electrons added (to the outer shell), leaving a -2 charge (8 protons, 10 electrons). </span>
<span>Their electrostatic attraction causes them to come together to form an ionic compound of CaO in a crystal lattice.</span>
Answer:indicates the number of electrons in an atom.

Answer:
Write the experimental procedure like a step-by-step recipe for your science experiment. A good procedure is so detailed and complete that it lets someone else duplicate your experiment exactly. Often it includes a sketch of how to set up the experiment. The directions may be numbered to be sure they are done in the correct order.
Explanation:
Answer: The pH at the equivalence point for the titration will be 0.65.
Solution:
Let the concentration of be x
Initial concentration of , c = 0.230 M
at eq'm c-x x x
Expression of :
Since ,methyl-amine is a weak base,c>>x so .
Solving for x, we get:
Given, HCl with 0.230 M , it dissociates fully in water which means = 0.230 M
will result in neutral solution, since
Remaining after neutralizing ions
The pH at the equivalence point for the titration will be 0.65.
