What is the Na+ concentration in each of the following solutions:

Chemistry
1 answer:
iren [92.7K]3 years ago
5 0

Sodium Sulfate = Na2(SO4) meaning there are two ions of Na+ in one mole of Sodium Sulfate the M stands for Molarity, defined as Molarity = (moles of solute)/(Liters of solution), So if the Na2SO4 solution is 3.65M that means one Liter of has 3.65 moles of Na2SO4, the stoichiometry of Na2SO4 shows that there would be two Na+ ions in solution for every one Na2SO4.

Therefore if 3.65 moles of Na2SO4 was to dissolve, it would produce 7.3 moles of Na+, and since this is still a theoretical solution, we can assume 1 L of solution.

Finally we find [Na+] = 2*3.65 = 7.3M

Use the same logic for parts b and c

What would the carbon dioxide part of a soft drink be classified as?
garik1379 [7]

Answer is: A. solute .

Solvation is the interaction of solvent (in this example water) with molecules or ions (in this example carbon dioxide)) in a solute.  

Solvent (usually a liquid, but can also be a solid or a gas) is a substance that dissolves a solute (dissolved in the solvent).

Solvent is always the same state of matter as the solution. In this example, soft drink is a liquid, so water is a solvent.

Answer:

<em>The correct option is B) a bridge to connect two landmasses over a stretch of water.</em>

Explanation:

A civil engineer is a person who deals with the designing and construction of infrastructure projects like the construction of roads, buildings, bridges, airports, tunnels etc. Civil engineering is one of the most oldest disciplines in engineering and it is broken into many sub-disciplines. A civil engineer might work for a private or a government-based organization. Hence, among the options mentioned in the question, the construction of a bridge is the most likely function of a civil engineer.
