The answer is C as it slowly destroys the ozone layer
It is E. because the predators will have slightly more meals with their prey slightly increasing population.
Answer:
37.25 grams/L.
Explanation:
- Molarity (M) is defined as the no. of moles of solute dissolved per 1.0 L of the solution.
<em>M = (no. of moles of KCl)/(volume of the solution (L))</em>
<em></em>
∵ no. of moles of KCl = (mass of KCl)/(molar mass of KCl)
∴ M = [(mass of KCl)/(molar mass of KCl)]/(volume of the solution (L))
∴ (mass of KCl)/(volume of the solution (L)) = (M)*(molar mass of KCl) = (0.5 M)*(74.5 g/mol) = 37.25 g/L.
<em>So, the grams/L of KCl = 37.25 grams/L.</em>
Answer:
false
Explanation:
the temperature of a substance can not remain constant as the substance changes from solid to liquid then finllay from liquid to gas. This is so because as a solid is heated it changes state and once it rechanges it boiling point it changes to gas or vapour.
