What are the resulting coefficients when you balance the chemical equation for the combustion of ethane, c2h6? in this reaction, ethane is burned in the presence of oxygen (o2) to form carbon dioxide (co2) and water (h2o). (g)+(g)→(g)+(g)

Explanation:

When ethane is burned in presence of oxygen, it produces carbon dioxide and water .

According to law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of reactants must be equal to the mass of products.

In order to get the same mass on both sides, the number of atoms of each element on product side must be same as the number of atoms of each element on reactant side.Thus the equations are balanced.

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
