Ascorbic acid, or vitamin C (C6H8O6, molar mass = 176 g/mol), is a naturally occurring organic compound with antioxidant propert
ki77a [65]

Answer:

The mass of ascorbic acid in 2.87×10−4 mol are 50,5 mg

Explanation:

Molar mass = 176 g/mol

Moles . molar mass = grams.

2,87 x10*-4 m . 176 g/m = 50,5 x10*-3 grams

A human can take one sweet lime and half to cover the daily requirement of vitamin C. =)

The mathematical relationship between gas solubility and pressure is called Henry's Law, solubility = kHPgas where kH is the Hen
Diano4ka-milaya [45]

Answer : The unit of k_H in mol/L.mm Hg is, 1.8\times 10^{-6}mol/L.mmHg

Explanation :

As we know that the k_H is the Henry's Law constant for argon at 25^oC is, 1.4\times 10^{-3}mol/L.atm

Now we have to determine the unit of k_H in mol/L.mm Hg

Conversion used for pressure from atm to mmHg is:

1 atm = 760 mmHg

So,

k_H=1.4\times 10^{-3}mol/L.atm\times \frac{1atm}{760mmHg}

k_H=1.8\times 10^{-6}mol/L.mmHg

Thus, the unit of k_H in mol/L.mm Hg is, 1.8\times 10^{-6}mol/L.mmHg

Why do colloids exhibit Brownian motion?
denis23 [38]
Brownian motion is a <span>movement of microscopic particles in a fluid, as a result of continuous bombardment from molecules of the surrounding medium.

As colloid is a fluid in which particles move due to bombardment from molecules, they exhibit Brownian motion

Ethane (CH) is one of many compounds that burns in oxygen to form carbon dioxide and water, as represented by the equation.
Nadya [2.5K]

Answer:

carbon dioxide and water.

Explanation:

Chemical equation:

2C₂H₆ + 7O₂      →    4CO₂ + 6H₂O

Reactants are present on the left side of chemical equation while products are present on the right side of chemical equation. In given chemical equation ethane and oxygen are reactant while carbon dioxide and water are product.

The given reaction is combustion reaction. Ethane is burnt in the presence of oxygen and produces carbon dioxide and water.

The reaction also follow the law of conservation of mass.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
