Answer:

where a cold air mass is replacing a warmer air mass. ... The air behind a cold front is noticeably colder and drier than the air ahead of it. When a cold front passes through, temperatures can drop more than 15 degrees within the first hour.

Explanation:

The effects from a cold front can last from hours to days. The air behind the front is cooler than the air it is replacing and the warm air is forced to rise, so it cools. As the cooler air cannot hold as much moisture as warm air, clouds form and rain occurs.

How many moles of KCl would be dissolved in 4 L of water to make a 2 M solution?
Nataly [62]
Answer:
             Moles  =  8 moles

Solution:
              Molarity is given as,

                         Molarity  =  Moles / Volume of Solution   ------ (1)

Data Given;
                   Molarity  =  2 M

                   Volume  =  4 L

Solving eq.1 for Moles,

                       Moles  =  Molarity × Volume of Solution

Putting values,

                       Moles  =  2 mol.L⁻¹ × 4 L

                       Moles  =  8 moles
