Answer:
three parts alcohol and seven parts water.
Explanation:
The total ounces of solution formed = 20 ounces
The solution of volume 12 ounces has one part alcohol and two parts water.
If there are three parts of solution, there is one part alcohol and two parts water.
for 12 ounces we have = 4 ounces alcohol and 8 ounces of water.
for 8 ounces of solution we have one part alcohol and three parts water.
It means in 8 ounces we have = 2 ounces alcohol and 6 ounces of water.
The total ounces of alcohol in the solution after mixing = 4 + 2 =6
the total ounces of water in the solution after mixing = 8 + 6 = 14
Thus the ratio of alcohol to water = 6:14 = 3: 7
it means three parts alcohol and seven parts water.
Answer:
Solution is 0.28 M
You can also say, [NaCl] = 0.28 mol/L
Explanation:
As you have a solute mass and the solution's volume, you may find the molarity concentration of solution.
Molarity specifies the moles of solute in 1 L of solution
We convert the volume of solution to L → 350 mL . 1L / 1000 mL = 0.350L
We convert the mass of solute to moles → 5.80 g . 1mol / 58.45 g = 0.0992 moles
Molarity (mol/L) = 0.0992 mol /0.350L = 0.28M
Answer:
The answer to your question is A. Decomposition
Explanation:
In the picture, we can observe that there is only one reactant that after the reaction are formed two products.
We observe that this is a decomposition reaction.
It is not a synthesis reaction, this reaction is the opposite of a decomposition reaction.
In a single-replacement and double-replacement reaction, there is an interchange of cations between the reactants, this does not happen in the picture.
