<span>If you used more water, the molarity would go down since molarity is moles/liter, and the opposite if you used more water.
If the acid absorbed water, the molarity would go down because the absorbed moisture will skew the weight of the acid up.
That would make the molarity go down since there would have been unreacted acid in the spilled liquid.</span>

Answer:
The pH of the solution is 1.00
Explanation:
The pH gives us an idea of the acidity or basicity of a solution. More precisely, it indicates the concentration of H30 + ions present in said solution. The pH scale ranges from 0 to 14: from 0 to 7 corresponds to acid solutions, 7 neutral solutions and between 7 and 14 basic solutions. It is calculated as:
pH = -log (H30 +)
The concentration of the H30+ ions is 0,1M:
pH= -log (0,1)
<em>pH=1.00</em>
Answer:
E = 3.9 x 10⁻²⁰ J
Explanation:
<u>Step 1:</u>
Before you can find the energy of the light, you need to find the wavelength. To find the wavelength, you need to use two equations:
w = c / f
In this formula, "w" is the wavelength (m), "c" is the speed of light (m/s), and "f" is the frequency. "C" is a constant with the value 3.0 x 10⁸ m/s. Since you have been given frequency and the constant, you can plug these values into the equation and solve for wavelength.
w = c / f
w = (3.0 x 10⁸ m/s) / (5.9 x 10¹³ sec⁻¹)
w = 5.1 x 10⁻⁶ m
<u>Step 2:</u>
To find the energy, you need to use the following equation:
E = hc / w
In this formula, "E" is the energy (J), "h" is Planck's constant (J/s), and "c" and "w" are the same as above. "H" is a constant with the value 6.626 x 10⁻³⁴ J/s. Since you found the wavelength and have been given the constants, you can plug them into the equation and find energy.
E = hc / w
E = (6.626 x 10⁻³⁴ J/s)(3.0 x 10⁸ m/s) / (5.1 x 10⁻⁶ m)
E = (1.99 x 10⁻²⁵) / (5.1 x 10⁻⁶ m)
E = 3.9 x 10⁻²⁰ J
