Answer and Explanation:

A combustion reaction occurs in the presence of oxygen (O2),and it gives carbon dioxide (CO2) and water (H2O) as main products.

So, in each case, we have to write O2 in the reactants side (with the given hydrocarbons), while CO2 and H2O will be in the products side:

a. Butane (C4H10):

2C_4H_{10}+13O_2\rightarrow8CO_2+10H_2O

The equation is balanced because in each side of the reaction there are: 8 C, 20 H and 26 O.

b. Cyclohexane (C6H12):

C_6H_{12}+9O_2\rightarrow6CO_2+6H_2O

The equation is balanced because in each side of the reaction there are: 6 C, 12 H and 18 O.

You are given a sample containing 0.90 moles of a substance.?. . a) How many atoms are in the sample if the substance is copper?
luda_lava [24]
For every mole of any substance or element, the total number of atoms is 6.022 x 10^23. This is called the avogadro's number. Hence, for a) for a 0.90 mole copper, the number of atoms is 5.42 x10^23. This also applies for B) which gives silver as given. For c), the number of molecules present in a compound is also the same. Thus, for a,b,and c, the answer is 5.42 x10^23.
