Answer: 2C4H10(g) + 13O2(g)----->8CO2(g) + 10H2O(g)

Explanation:

From the general formula for combustion of alkanes:

CnH2n+2 + 3n+1/2 O2------------> nCO2 + (n+1)H2O

We have:

C4H10(g) + 13/2 O2(g) ---------> 4 CO2(g) + 5H2O(g)

Now we can multiply by 2 to obtain the lowest whole number coefficients

2C4H10(g) + 13O2 (g) ---------->8CO2(g) + 10 H2O(g)

We had to multiply by two because it is the integer that will give us the lowest coefficient. Multiplying through by 2 will give the expected result.

Why are ions usually formed during the interaction of metal with nonmetal and not between two metals? ​
Alik [6]

Explanation:

Ions are always formed when metals and non-metals interact because metals are electropositive. They willing release electrons to non-metals that are electronegative.

This activity results in charge separation. The transfer of electrons from one specie to another is what results in an ionic bond and the precedence of charged particles.

Between non-metals, the electrons are jointly shared. Therefore, there is no charge separation.

At 393 K, the pressure of a sample of nitrogen is 1.07 atm. What will the pressure be at 478 K, assuming constant volume?
True [87]

Answer:

About 1.301 atm

Explanation:

The formula that you should is PV=nRT, where P stands for pressure, V stands for volume, n stands for the number of moles, R stands for the universal gas constant, and T stands for temperature in Kelvin. Since the volume, number of moles, and universal gas constant don't change, you don't need to worry about them.

1.07V=393nR

PV=498nR

P=1.301 atm. Hope this helps!

If you are operating a power driven vessel that is underway in conditions of restricted visibility, what should you do
swat32
If you are operating a power driven vessel that is underway in condition of restricted visibility, you are expected to do the following: sound prolonged blasts every two minutes. If the vessel is underway but is not moving, it is expected to sound two prolonged blast every two minutes. When one hears any of the signal above, one is expected to reduce speed to the minimum that is needed to keep on course.
