<span>The answer is "D" where the number of collisions per unit area is reduced by one-half. Drawing back on the piston means the volume is increased. The pressure is reduced. There are fewer collisions when the pressure is reduced.</span>
An occluded front forms when a warm air mass is caught between two cooler air masses.
Answer:
0.2
Explanation:
1. First, figure out the molar mass of said element(s).
The molar mass of carbon is 12.0107. Whether you round this or leave it as is depends on your's and/or your teacher's personal preference.
2. Next, convert grams to moles by dividing the initial mass of carbon by the molar mass. Round if neccecary.
2.4g ÷ 12.0107g/mol = 0.2mol
One danger associated with blizzards is that blizzards are severe winter storms that pack a combination of blowing snow and wind resulting in very low visibilities. While heavy snowfalls and severe cold often accompany blizzards, they are not required. Sometimes strong winds pick up snow that has already fallen, creating a blizzard.
I hope this helps.
