Answer C
hope this helps!
Water, Water is not a pure substance. It is a mixture, and Chromatography
The pressure of the gas = 40 atm
<h3>Further explanation</h3>
Given
200 ml container
P = 2 atm
final volume = 10 ml
Required
Final pressure
Solution
Boyle's Law
At a fixed temperature, the gas volume is inversely proportional to the pressure applied

Input the value :
P₂ = P₁V₁/V₂
P₂ = 2 x 200 / 10
P₂ = 40 atm
<span>H and Li have a +1 charge. Cl and OH have a -1 charge. When written out it should look like this:
H(+1) + Cl(-1) + Li(+1) + OH(-1) --> H2O + Li(+1) + Cl(-1)
if you wanted the net ionic equation it would be:
H(+1) + OH(-1) --> H2O</span>
Answer:
The energy required to start a reaction is called the ACTIVATION ENERGY.
Explanation:
Enzymes are proteins that function as biological catalysts to speed up the rate of chemical reactions in cell without being changed into a different molecule.
