Which gas, acetylene ($C_2H_2$), a gas used in welding, or ethane ($C_2H_6$) has a stronger carbon to carbon bond energy and bond length? Explain why.
The modern chemical bond is conceived to be a region of high electron between 2 positively charged atomic nuclei, such that internuclear is repulsion is negated, and a net attractive...

When 3.0 g of carbon is burnt in 8.0 g of oxygen, 11.0 g of carbon dioxide is produced. what is the mass of carbon dioxide will be formed when 3.0 g of carbon is burnt in 50.0 g of oxygen? Which law of chemical combination will govern the answer?
When a $3.0*g$ mass of carbon is burnt in an $8.0*g$ mass of dioxygen, the carbon and the oxygen are stoichiometrically equivalent. Of course, the combustion reaction proceeds according to...

Ethane, $C_2H_6$, reacts with molecular oxygen to produce carbon dioxide and water. How do you write the balanced chemical equation for this reaction?
This is a combustion reaction of an alkane with oxygen. It is exothermic ($DeltaH<0$), and can be balanced in normal methods for ie ensuring that the total number of atoms...

What is a balanced chemical equation, including physical state symbols, for the combustion of gaseous ethane into gaseous carbon dioxide and gaseous water?
So two questions: is mass balanced?; is charge balanced? If you like you can double the equation to eliminate the half-integral coefficient; the mass transfer, the is still the same....

Write a balanced equation for the combustion of liquid penetrate C5H12, in which it combines with gaseous oxygen to form gaseous carbon dioxide and gaseous water?
your equation works. However, it is better to use the smallest possible coefficients. Divide your by 2. It still works. Start by using the 5 carbons in the hydrocarbon...

If 5.49 mol of ethane ($C_2H_6$) undergoes combustion according to the unbalanced equation $C_2H_6+O_2->CO_2+H_2O$, how much oxygen is required?
The balanced equation of the combustion of ethane is: $2C_2H_6+7O_2->4CO_2+6H_2O$ Then number of mole of oxygen that will be needed to completely react with $5.49mol$ of ethane could be calculated...

When ethane, $C_2H_6$, reacts with chlorine gas the main product is $C_2H_5Cl$ but small amounts of $C_2H_4Cl_2$ are produced. What is the percent yield of $C_2H_5Cl$ if the reaction of 125g of ethane with 255g of chlorine gas produced 206g of $C2H_5Cl$?
The key here is to focus solely on the reaction that produces chloroethane, $"C"_2"H"_5"Cl"$, and ignore the one that produces dichloroethane, $"C"_2"H"_4"Cl"$, the side product of the reaction. Start by...

Given the equation $C_2H_6(g) + O_2(g) -> CO_2 (g) + H_2O(g)$ (not balanced), what is the number of liters of $CO_2$ formed at STP when 240.0 grams of $C_2H_6$ is burned in excess oxygen gas?
The first thing to do here is make sure that you have a balanced chemical equation. The equation given to you is actually unbalanced, so focus on writing a balanced...

Ethene undergoes incomplete combustion to form carbon dioxide, carbon monoxide and water vapour. If the ratio of carbon dioxide to carbon monoxide formed is 9:1 when x cm^3 of ethene is burnt, what is the volume of oxygen gas consumed in the reaction?
Ethene undergoes incomplete combustion to form carbon dioxide, carbon monoxide and water vapour. The balanced equation of this incomplete combustion reaction is as follows. $C_2H_4(g)+5/2O_2(g)->CO_2(g)+CO(g)+2H_2O(g)$ But as per question the...

The solubility of carbon dioxide in water is 0.161 g $CO_2$ in 100 mL of water at 20°C and 1.00 atm. A soft drink is carbonated with carbon dioxide gas at 5.50 atm pressure. What is the solubility of carbon dioxide in water at this pressure?
$"8.855 g/L"$ This is just asking you to calculate the new molar (i.e. molar solubility) at a different pressure, i.e. use the . (We'll end up converting...
