Under what conditions of temperature and pressure is a gas least soluble in water

Chemistry

The conditions of temperature and pressure in which a gas least soluble in water is low pressure and high temperature.

<h3>What is Henry Law?</h3>

The amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid, according to Henry's law.

From this law it is clear that:

  • As the pressure of the gas increases solubility of the gas on the liquid also increases.

But if the temperature of the liquid decreases then the solubility of the gas also increases.

Hence at low pressure and high temperature, gas is least soluble.

Answer:

This question appears incomplete

Explanation:

This question appears incomplete because of the absence of options. However, hydrogen is placed in group 1 because it has just one electron in it's outermost shell (which happens to be the only shell it has) just like every other group 1A/group 1 element. While helium is placed in group 8A/group 18 because it has a completely filled outermost shell (which is also the only shell it has) just like every other element in group 8A/group 18.

What is the empirical formula for a compound composed of 0.0683 mol of carbon ( C ), 0.0341 mol of hydrogen ( H ), and 0.1024 mo
liubo4ka [24]

The empirical formula for a compound composed of 0.0683 mol of carbon ( C ), 0.0341 mol of hydrogen ( H ), and 0.1024 mol of nitrogen ( N ) is  C_2HN_3.

<h3>What is the empirical formula?</h3>

An empirical formula tells us the relative ratios of different atoms in a compound.

Given data:

Moles of carbon = 0.0683 mol

Moles of hydrogen = 0.0341 mol

Moles of nitrogen = 0.1024 mol

Dividing each mole using the smallest number that is divided by 0.0341 moles.

We get:

Carbon= 2

Hydrogen=1

Nitrogen=3

The empirical formula for a compound isC_2HN_3.

How many moles are in 120g of NH3
Simora [160]

Moles of NH₃ : = 7.059

<h3>Further explanation</h3>

Given

120 g NH₃

Required

moles NH₃

Solution

The mole is the number of particles contained in a substance

<em>1 mol = 6.02.10²³ </em>

Moles can also be determined from the amount of substance mass and its molar mass

Mol = mass : Molar mass

So for 120 g (molar mass of NH₃ = 17 g/mol) :

= 120 g : 17 g/mol

= 7.059
