Complete these metric conversions: 53 m - mm*
EleoNora [17]

Answer:

53 meters = 53000 millimeters

Explanation:

In this question we have to convert meters into millimeters .

By metric conversion,

Since, 1 meter = 1000 mm

Therefore, 53 meters = 53 × 1000

                                  = 53000 millimeters

53 meters = 53000 millimeters is the answer.

Answers:

1) <span>Breaking Solvent-Solvent Attractions is an Endothermic Process.

2) </span><span>Breaking Solute-Solute Attractions is an Endothermic Process.

3) </span><span>Forming Solute-Solvent Attractions is an Exothermic Process.

Explanation:
                   When a solute is dissolved in solvent it either releases heat or absorbs heat depending upon the the interactions broken and interactions formed. At first, the solvent solvent interactions are broken , this process requires heat which is provided either from external source or is provided by the forming of solute solvent bond forming process which is exothermic.

When the solvent molecules get apart the solute particles enter to form interactions with elimination of heat. So, if the heat required to break solvent solvent interactions is greater than the heat provided by solute solvent interactions formation then the solute will not dissolve at room temperature and vice versa.</span>
