the triple point of co2 occurs at nearly 1000 times greater pressure and at a lower temperature than the triple point of h2o. ba
IceJOKER [234]

Since liquid CO2 cannot exist at pressures lower than 5.11 atm, the triple point is defined as 56.6 °C and 5.11 atm.

Are CO2 liquids explosive?

Although it can impair judgement at high doses, carbon dioxide is neither poisonous nor combustible. Asphyxiation is typically seen as the primary risk associated with CO2. The Boiling Liquid Expanding Vapour Explosion, however, is a serious risk connected to compressed CO2 (BLEVE)

What PSI does CO2 turn into liquid at?

Only at pressures more than 5.1 atm does liquid carbon dioxide form; the triple point of carbon dioxide is approximately 518 kPa at 56.6 °C. Depending on the pressure, the liquid's boiling point ranges from -70°F to +88°F. The expansion ratio when vaporised at 60°F is 535:1. CO2 is a gas or liquid.

Calculate the molality of a solution formed by adding 6.30 g NH4CL to 15.7 g of water
babymother [125]

Answer:

Molality = 7.5 mol/kg

Explanation:

Given data:

Mass of NH₄Cl = 6.30 g

Mass of water = 15.7 g (15.7/1000 =0.016 kg)

Molality = ?

Solution:

Formula of molality:

Molality = Moles of solute / mass of solvent in gram

Now we will first calculate the number of moles of solute( NH₄Cl )

Number of moles = mass/ molar mass

Molar mass of  NH₄Cl = 53.491 g/mol

Number of moles = 6.30 g/  53.491 g/mol

Number of moles =  0.12 mol

Now we will calculate the molality.

Molality = Moles of solute / mass of solvent in gram

Molality =  0.12 mol / 0.016 kg

Molality = 7.5 m

or        (m=mol/kg)

Molality = 7.5 mol/kg
