A mixture having a uniform composition where the components can't be seen separately and all components are in the same state best describes a solution.

In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.

The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Answer:

Explanation:

it can be A because if it says that a solution is consisting of minute particles suspended in a medium that start moving about as soon as the mixing process stops First a solution cannot be seen separately , and a solution does not move when the mixing process stops because any substance put into a liquid dissolved and form a solution therefore C is the correct answer.

For the reaction shown here, 3.5 mola is mixed with 5.9 molb and 2.2 molc. what is the limiting reactant?3a+2b+c→2d

Misha Larkins [42]

For equation A + 3B + 2C ---> 2D, 1 mole of A will produce 2 moles of D 3 moles of B will produce 2 moles of D, so 1 mole of B will produce 2/3 moles of D 2 moles of C will produce 2 moles of D, so 1 mole of C will produce 1 mole of D If only 1 mole of B is present, only 2/3 moles of D can be produced. This is regardless of the number of moles of A and C. B is the limiting reactant and the maximum number of moles of D expected is 2/3.

3. Determine the moles of sodium, Na, containing 7.9x1024 atoms.

-BARSIC- [3]

Answer:

12.7mol Na.

Explanation:

Hello there!

In this case, according to the concept of mole, which stands for the amount of substance, we can recall the concept of Avogadro's number whereby we understand that one mole of any substance contains 6.022x10²³ particles, for the given atoms of sodium, we can calculate the moles as shown below:

$7.9x10^{23}atoms*\frac{1mol}{6.022x10^{23}atoms} \\\\$
