Hi, I believe this question is asking what charge Phosphorus will have when it forms an ion. If that is the case, you will see that it based on the column it is in, neutral Phosphorus has 5 valence electrons. When it becomes an ion (has 8 valence electrons), it will GAIN three electrons. Meaning, we can predict that Phosphorus will have a 3- charge when it becomes an ion.
Cell signalling is a process by which cells communicate with each other and transfer messages.
<h3>What is a receptor?</h3>
A molecule inside or on the surface of a cell binds to a specific substance and causes a specific effect in the cell.
Cell signalling is a process by which cells communicate with each other and transfer messages. When a signal molecule binds to a receptor protein, changes occur in the receptor proteins. Two changes are listed below:
1. The receptor protein undergoes conformational changes and acts as an enzyme.
2. The receptor protein that makes a second messenger molecule that leads the reaction further to other cells or molecules.

Answer:
sup brö how is it back home?
Explanation:
just curious you know
Answer:
a. 1 mole of acid is equal to one equivalent.
b. 1.00 moles of HCl are found.
c. 1L of 2.00M NaOH is needed to reach the equivalence point
Explanation:
HCl reacts with NaOH as follows:
HCl + NaOH → NaCl + H2O
<em>Where 1 mole of HCl reacts with 1 mole of NaOH. The reaction is 1:1</em>
a. As the reaction is 1:1, 1 mole of acid is equal to one equivalent
b. The initial moles of HCl are:
1.00L * (2.00moles HCl / 1L) = 2.00 moles of HCl
At the halfway point, the moles of HCl are the half, that is:
1.00 moles of HCl are found
c. At equivalence point, we need to add the moles of NaOH needed for a complete reaction of the moles of HCl. As the moles of HCl are 2.00 and the reaction is 1:1, we need to add 2.00 moles of NaOH, that is:
2.00moles NaOH * (1L / 2.00mol) =
1L of 2.00M NaOH is needed to reach the equivalence point
