Answer:
[H+] = 1.66 x
Explanation:
To find the [H+] concentration of a solution, we can use the formula:
Let's plug in the pH.
Evaluate the exponent.
[H+] = 1.66 x

Answer:
82.9% Is the percent yield
Explanation:
First, we need to balance the equation.
Ca(CO3) + 2HCl → H2O + CO2 + CaCl2
Since the problem tells you that the excess reactant is Ca(CO3), we just need to Stoichiometry to solve for the theoretical yield.

=120.707 g (theoretical yield)
Take your actual yield of 100g, divide that by 120.707, then multiply that decimical by 100.
<h2>Hello!</h2>
The answer is: -97.37° C
<h2>Why?</h2>According to the Charles and Gay-Lussac's Law we have that:
Where:
<em>v</em> is the volume of the gas
<em>t</em> is the temperature of the gas
<em>k </em>is the proportionality constant
From the Gay-Lussac's Law we also have the following relation:
Since we need to find the new temperature (T2) we can use the last equation:
We are asked to find the temperature in Celsius degrees, so, we must convert the result (in K) to Celsius degrees:
So, the temperature is -97.37° C
