Answer:
1.89 × 10^-11 M
Explanation:
Recall that;
[H^+] [OH^-] = 1 × 10^-14
[H^+] = concentration of hydronium ions
[OH^-] = concentration of hydroxide ion
Where [OH^-] = 5.3 × 10−4 M
[H^+]= 1 × 10^-14/5.3 × 10−4
[H^+]= 1.89 × 10^-11 M
A typical phase diagram has pressure on the y-axis and temperature on the x-axis. As we cross the lines or curves on the phase diagram, a phase change occurs. In addition, two states of the substance coexist in equilibrium on the lines or curves.Jun 6, 2016
Based on the information on the student looking for an element that will bond with sodium, the element that will likely bond with sodium is bromine.
<h3>How do elements bond?</h3>
Elements bond with one another in a chemical manner to form compounds, which cannot be broken down into their constituent elements without being destroyed.
According to this question, a student is looking for an element that will bond with sodium (Na) with the knowledge that table salt is a compound of sodium and chlorine (Cl).
This suggests that an element that will likely bond with sodium must be in the same group with chlorine because they will possess the same chemical properties.
Therefore, based on this information, the element that will likely bond with sodium is bromine.

Answer:
0.170 M
Explanation:
As this is a <em>series of dilutions</em>, we can continuosly<em> use the C₁V₁=C₂V₂ formula </em>to solve this problem:
For the first step:
- 59.0 mL * 1.80 M = 258 mL * C₂
Then for when 129 mL of that 0.412 M are diluted by adding 183 mL of water:
- V₂ = 129 mL + 183 mL = 312 mL
Using <em>C₁V₁=C₂V₂:</em>
- 129 mL * 0.412 M = 312 mL * C₂
Answer:
2
Explanation:
There are 3 carbons on the right side
there are only two on the left side....you need one more ...so add one more... change the '1' coefficient in front of C to '2'
