A sample of mercury has a mass of 607.0 lb and a volume of 0.717 ft. What is its specific gravity? Number SG= What are the units

stepan [7]

Answer:

Specific gravity of mercury is 13.56 and it is an unit-less quantity.

Explanation:

Mass of the mercury = m = 607.0 lb = 275330.344 g

1 lb = 453.592 g

Volume of the mercury = v = $0.717 ft^3=20,303.18 mL$

$1 ft^3 = 28316.847 mL$

Density of the mercury = d= $\frac{m}{v}=\frac{275330.344 g}{20,303.18 mL}$

d = 13.56 g/mL

Specific gravity of substance = Density of substance ÷ Density of water

$S.G=\frac{d}{1 g/mL}$

Specific gravity of mercury :

$S.G=\frac{13.56 g/mL}{1 g/mL}=13.56$ (unit-less quantity)

Which statement is true about HCI?

katen-ka-za [31]

Answer:

d- it is an acid because it increases the concentration of hydronium ions

Explanation:

HCl; hydrochloric acid is an acid because it increases the concentration of hydronium ions when in solutions.

An acid is a substance that interacts with water to produce excess hydroxonium ions H₃O⁺ in an aqueous solution.

For example:

HCl + H₂O → H₃O⁺ + Cl⁻

HCl is classified as a strong acid due to its complete ionization when in solutions.
