- Acids are substances that form H^+ ions when dissolved in water.

- Bases are substances that form OH^- ions when dissolved in water.

- Substances with a Low pH ( < 7) have more H^+ ions are classified as Acids.

- Substances with a Higher pH ( > 7) have more OH^- ions and are classified as Bases.

The pH of a solution/substance is a measure of the molar concentration of hydrogen ions in solution/substance and as such, is a measure of the Acidity or Basicity of the solution/substance.

The letters pH stands for " Power of Hydrogen." and the:

Numerical Value: is defined as the Negative Base 10 Logarithm of the Molar Concentration of Hydrogen Ions.

pH = log10[ H^+]

A steel container with a movable piston contains 2.00 g of helium which was held at a constant temperature of 25 °C. Additional

Answer: D) 1.00 g

Explanation:

According to the Avogadro's law, the volume of gas is directly proportional to the number of moles of gas at same pressure and temperature. That means,

$V\propto n$

or,

$\frac{V_1}{V_2}=\frac{n_1}{n_2}$

where,

$V_1$ = initial volume of gas = 2.00 L

$V_2$ = final volume of gas = 3.00 L

$n_1$ = initial moles of gas = $\frac{\text {Given mass of helium}}{\text {molar mass of helium}}=\frac{2.00g}{4g/mol}=0.500mol$

$n_2$ = final moles of gas = ?

Now we put all the given values in this formula, we get

$\frac{2.00L}{3.00L}=\frac{0.500mol}{n_2}$

$n_2=0.75mole$

Mass of helium = $moles\times {\text {molar mass}}=0.75\times 4=3.00g$

Thus mass of helium added = (3.00-2.00) g = 1.00 g

Answer: one molecule of O2.

Explanation: sweet i just took a guess but I believe that if 3 o2 molecules - 2 h2 molecules I think that its just basic maths and it is C because 3-2 = 1 and its o2 remaining, sorry if I’m wrong.
