Answer:
The resulting molarity is 6M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
12 M x 0,5L = C2 x 1,0 L
C2= (12 M x 0,5 L)/1,0 L
<em>C2= 6 M</em>
Answer: the molecular formula is C10H20O

As the volume of the confined gas decreases at the constant temperature, the pressure exerted by the gas increases.
Answer:
20.9%
Explanation:
I took the test i hope this helps:)
<span>Decreasing the temperature will decrease the pressure of a gas inside a closed cubical container.
In a closed container, the Volume (V) is fixed and the no of mole of the gas(n) are also fixed. So, we write the gas equation : PV = nRT
Here, V,R and n are constants.
So, Pressure is directly proportional to the temperature. Thus, on increasing the temperature, pressure will increase and on decreasing the temperature, the pressure will decrease.</span>
