Molarity = Moles / Liters! So in this instance, if you have 0.45 moles of NaCl, and we convert 300.0 mL to 0.3 L, we would plug in M = 0.45/0.3. The answer would be 1.5 M NaCl!
Answer: 
is missing
Explanation:
In a nuclear reaction, the total mass and total atomic number remains the same.
For the given reaction:
To calculate A:
Total mass on reactant side = total mass on product side
4 + 9 = 12 + A
A = 1
To calculate Z:
Total atomic number on reactant side = total atomic number on product side
2 + 4 = 6 + Z
Z = 0
Hence, missing is .
C. Outward pressure caused by heat
If the heating is done on one small area on the top, there will be convection. If the heating is restricted to a small fraction of the heating area, then within that area the heating will go deeper than anywhere else on the surface. Then unheated area will have a shallower region of high temperature. Then some convection will occur in the deeper layers, causing some motion on top.
This happens quite a bit during welding. Convection is very significant in welding, even when the heating is from the top.
