As latitude decreases, average yearly temperature generally
Answer:
The new molarity is 0,96 M.
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
2,4 M x 100ml = C2 x 250 ml
C2= (2,4 M x 100ml)/250 ml
<em>C2= 0,96 M</em>
2H2 + O2 ---->2H2O
number of moles in reaction 2 mol 1 mol 2 mol
number of liters in the reaction 2*22.4 L 1*22.4 L 2*22.4L
We can see that volumes of the gases are proportional to coefficients in the reaction ( if gases are under the same conditions), so we can write
2H2 + O2 ---->2H2O
2 L 1 L 2 L
given 40 L ( 25 L) 40 L
We can see that we have excess of O2,
because if 2 L H2 are needed 1 L O2, then 40 L of H2 are needed 20 L O2.
So, limiting reactant is H2, and we will need to calculate Volume of H2O using H2.
2L H2 give 2L H2O(gas), so 40 L H2 give 40 L H2O.
Answer:
non polar molecules
Explanation:
Ethyl alcohol will dissolve in water in all proportions because the polar molecules interact with each other freely. In contrast, gasoline is a nonpolar molecule. hope that helped...
