Assuming no change in temperature and pressure, calculate the volume of O2 (in liters) required for the complete combustion of 1

Natali [406]

Answer : The number of moles of oxygen gas required are, 4.49 moles.

Explanation :

The balanced chemical reaction is:

$2C_4H_{10}(g)+13O_2(g)\rightarrow 8CO_2(g)+10H_2O(l)$

First we have to calculate the moles of butane gas.

As we know that, 1 mole of substance occupies 22.4 L volume of gas.

As, 22.4 L volume of butane gas present in 1 mole of butane gas

So, 15.5 L volume of butane gas present in $\frac{15.5}{22.4}=0.692$ mole of butane gas

Now we have to calculate the moles of oxygen gas.

From the balanced chemical reaction we conclude that,

As, 2 moles of butane gas react with 13 moles of oxygen gas

So, 0.692 moles of butane gas react with $\frac{13}{2}\times 0.692=4.49$ moles of oxygen gas

Therefore, the number of moles of oxygen gas required are, 4.49 moles.

What atom has 8 protons and 10 electrons?

Lorico [155]

Answer:

In your case, you have 8 protons and 10 electrons. This means that the atom will carry a total 2 xx (1-) = 2- net charge. Therefore, you are dealing with an anion that carries a 2- net charge, i.e. it has two more electrons than it does protons.
