You said at least 6 methods meaning I can give more than 6.
Hope it helps.
Yes. It is only through creativity that scientific inquiry exists. Someone had the wacky creative idea that there should be something that is so strong, and inflammable, and just generally amazing like a super... thing! And tadaaah, we have Kevlar. The stuff in bullet proof vests.
Answer:
The limiting reactant is propene,
.
Explanation:

Moles of nitrogen propene = 2 mol
Moles of oxygen = 10 mol
According to reaction, 2 moles of propene reacts with 9 moles of oxygen gas, then 2 moles of propene will react with:

According to the question, we have 10 moles of oxygen gas, which is more than 9 moles of oxygen gas. This indicates that propene is present in a limiting amount hence, it is a limiting reactant.
The limiting reactant is propene, hence the correct answer is the
.
Answer: 1 mol of carbonate to 2 mol of acid
Explanation:
To calculate the number of moles for given molarity, we use the equation:
a)
b) 
Thus the mole ratio of carbonate to acid is =
