Give an example of a non-biological chemical reaction that involves carbon. Name the process that converts a solid compound into
xxMikexx [17]

Answer:

The process that converts a solid mcompound into a gas is sublimation.

E.g- dry ice, solid iodine and ammonium salts

when the above solid are heated, only particles which are found on the surface of the solid gain enough energy and break all forces of attraction and form a gas.

3.95 g of sugar (C6H12O6) is dissolved in water to make 158 mL of solution. Find the molarity.
12345 [234]

Answer:

[C₆H₁₂O₆] = 0.139 M

Explanation:

Molarity si defined as a sort of concentration. It indicates the moles of solute that are contained in 1 L of solution.

We can also say, that molarity are the mmoles of solute contained in 1 mL of solution.

For this case, the solute is sugar (glucose). Let's determine M (mmol/mL)

(3.95 g . 1mol / 180g) . (1000 mmol / 1mol) / 158 mL

We determine moles, we convert them to mmoles, we divide by mL

M = 0.139 M

Moles = 3.95 g . 1mol / 180g → 0.0219 mol

We convert mL to L → 158 mL . 1L/1000mL = 0.158L

M = 0.0219 mol / 0.158L = 0.139 M
