Answer:
4 > x/2.1
Step-by-step explanation:
4 cannot be less than anything, so the inequality sign has to be "eating" the 4.
4 > ?
The quotient of a number x and 2.1 is simply saying division
4 > x/2.1
PH
is a scale which measures the acidity or alkalinity of a solution. It ranges
from a level of 1 to 14. A pH which range from 1 to 6 represents an acidic
substance. At pH of 7, signifies the solution is neutral. And at a pH of 8-14
represents a basic solution. pH is expressed as the negative logarithm of the
concentration of hydronium ions. To determine the factor of how the pH will change, we use the definition of the pH.<span>
pH = -log [H+]
5.50 = -log [H+]
[H+] = 10^-5
2.00 = -log [H+]
[H+] = 10^-2
</span>10^-5 / 10^-2 = 0.001
The rate of reaction would change by a factor of 0.001 as the pH change from 5.5 to 2.0
"<span>Solve Z squared 2 = 1" sounds strange. Do you mean "z squared," or do you mean "Z^2?"
Z^2 = 1 can be solved by finding the sqrt of both sides: Z = plus or minus 1.</span>

Determine the volume of the chocolate milk
Since, the mixture produces a chocolate milk, then the volume is the addition of milk in the pitcher and the chocolate syrup.
i.e.
<em>Hence, there are 4.325 liters of chocolate milk in the pitcher</em>
