Answer:
The name of it is Sulfur Hexafluoride
Explanation:
Bonus fact: It is over 5 times heavier than air so when inhaling it, it makes your voice go very deep. The opposite of helium some would say
Exothermic is a chemical reaction in which heat is released. Lighting a candle is an example of an exothermic because the flame is the heat being released.
Molar mass = 212.996 g/mol
,,
You basically add the total atomic weight, these weights can be found on a periodic table
Molarity = moles / liter
a) M = 2/4 = 0.5 M
b) Moles = 4/(30 + 16 + 1)
= 0.085
M = 0.085 / 2 = 0.0425 M
c) Moles = 5.85 / (23 + 35.5)
= 0.1
M = 0.1 / 0.4
= 0.25 M
