At what pressure will CO2 dissolve in water? ​

Chemistry

5 0
Carbon dioxide is only slightly soluble in water. One liter of water dissolves about 1.4 gm of the gas at 25 degree Celsius. Chlorine and hydrogen sulphide are much more soluble in water. A solution of CO2 in water is called carbonic acid (H20 + CO2= H2CO3).

gregori [183]

Answer:

Explanation:

Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. Include all free radicals by right-clicking on an atom on the canvas and then using the Atom properties to select the monovalent radical.

How many molecules are there in 223 grams of Na2SO4?
Harlamova29_29 [7]
<h3><u>Answer;</u></h3>

= 9.45 × 10^23 molecules

<h3><u>Explanation; </u></h3>

The molar mass of Na2SO4 = 142.04 g/mol

Number of moles = mass/molar mass

                             = 223/142.04

                             =  1.57 moles

But;

1 mole = 6.02 × 10^23 molecules

Therefore;

1.57 moles = ?

= 1.57 × 6.02 × 10^23 molecules

<u>= 9.45 × 10^23 molecules </u>
