Do you think creativity can contribute to scientific inquiry and investigation?
Firdavs [7]
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.

If you have 2 Moles of C3H6 and 10 Moles of O2, which reactant is limiting the following reaction: 2C3H6 + 9O2 → 6CO2 + 6H2O?
Hatshy [7]

Answer:

The limiting reactant is propene, C_3H_6.

Explanation:

2C_3H_6 + 9O_2 \rightarrow 6CO_2 + 6H_2O

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:

=\frac{9}{2}\times 2mol=9\text{mol of oxygen gas}

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 C_3H_6.

A volume of 25cm3 of a carbonate solution of concentration 0.2mol dm-3 was neutralized by 20 cm3 of acid of concentration 0.5 mo
Galina-37 [17]

Answer: 1 mol of carbonate to 2 mol of acid

Explanation:

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution in ml}}  

a) \text{Moles of carbonate}=\frac{0.2moldm^{-3}\times 25cm^3}{1000}=0.005mol

b) \text{Moles of acid}=\frac{0.5moldm^{-3}\times 20cm^3}{1000}=0.01mol

Thus the mole ratio of carbonate to acid is = \frac{0.005}{0.01}=\frac{1}{2}
