Balance the equation first:

1C4H10 + 13O2 ----> 8CO2 + 10H2O

As we know oxygen is in excess, butane is the limiting reactant.
the ratio between butane and CO2 is 1-8
Therfore
1:8
6:x
x=48
48 moles of CO2 will be produced

Answer: 24 moles

Explanation:

Combustion is a type of chemical reaction in which hydrocarbon is oxidized to carbon dioxide and water.

The balanced chemical reaction for combustion of butane is :

2C_4H_{10}+13O_2\rightarrow 8CO_2+10H_2O

According to stoichiometry,

Given: Oxygen is the excess reagent. Thus butane is the limiting reagent as it limits the formation of product.

2 moles of butane gives 8 moles of carbon dioxide.

Thus 6 moles of butane will give=\frac{8}{2}\times 6=24moles of carbon dioxide.

Why sulphur has two melting point values
Fofino [41]

I don't know how well known/accepted this is (it's in my textbook so I'm guessing it's right), but Sulphur has two forms - the alpha and beta forms ,apparently gamma sulphur exists as well.

The alpha form is rhombic, yellow in color and has a MP of 385.8 K. The beta form is colorless and has a MP of 393 K and is formed by melting rhombic sulphur and cooling it till a crust forms on top. Poke a hole and pour out the liquid inside and you get beta sulphur. The transition point is 369K - below it, alpha sulphur is stable and above it, beta sulphur is stable. Both have helped. I had to pull out an old textbook and that's something that I don't usually do.

In the mathematical equation showing that pressure (P) multiplied by volume (V) remains equal to a constant (k) pressure and vol
hram777 [196]

Answer:

Inversely

Explanation:

pV = k

When p increases, V must decrease for k to remain constant.

When V increases, p must decrease for k to remain constant.

When the product of two variables is a constant, they are inversely proportional  to each other.
