A 3.42 gram sample of an unknown gas is found to occupy a volume of 1.90 L at a pressure of 547 mm Hg and a temperature of 33 °C
liq [111]
Use the Ideal Gas Law to find the moles of gas first.

Be sure to convert T from Celsius to Kelvin by adding 273.

Also I prefer to deal with pressure in atm rather than mmHg, so divide the pressure by 760 to get it in atm.

PV = nRT —> n = PV/RT
P = 547 mmHg = 547/760 atm = 0.720 atm
V = 1.90 L
T = 33°C = 33 + 273 K = 306 K
R = 0.08206 L atm / mol K

n = (0.720 atm)(1.90 L) / (0.08206 L atm / mol K)(306 K) = 0.0545 mol of gas

Now divide grams by mol to get the molecular weight.

3.42 g / 0.0545 mol = 62.8 g/mol

Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH-] is 1 x 10-2 mol/L. Is this solution acidid
Lilit [14]

Answer:

[H⁺] = 1.0 x 10⁻¹² M.

Explanation:

<em>∵ [H⁺][OH⁻] = 10⁻¹⁴. </em>

[OH⁻] = 1 x 10⁻² mol/L.

∴ [H⁺] =  10⁻¹⁴/[OH⁻] = (10⁻¹⁴)/(1 x 10⁻² mol/L) = 1.0 x 10⁻¹² M.

∵ pH = - log[H⁺] = - log(1.0 x 10⁻¹² M) = 12.0.

∴ The solution is basic, since pH id higher than 7 and also the  [OH⁻] > [H⁺].

The table above shows data from a laboratory experiment in which Andrew measured conclusion from this experiment?
puteri [66]

We know that the particles in a matter have energy. They have kinetic energy, potential energy, chemical energy, electrical energy etc.

When we give heat to a matter it gains energy and there is an increase in its internal energy. Or we can say that particles in a matter have more energy at higher temperature than particles in a matter at low temperature

As ice is formed below zero degree celsius so the particles in ice must have lesser energy than water at higher temperature.

Thus true statement will be

The particles in boiling water have more energy than the particles in ice water do.
