Answer:

C. nicotine

Explanation:

Nicotine is a derivative of tobacco, it can be found in smoke and stimulates the brain. It is produced by burning cigarettes and is the main cause of the dependence that the smoker presents. This is because, when you take a cigarette, nicotine reaches the brain in about 9 seconds and acts on the central nervous system, causing a pleasant feeling of well-being. However, this sensation is transient and the more one smokes the more the body adapts to the drug and the addiction increases, requiring more doses of nicotine in the body, ie increasing the amount of cigarettes consumed.

When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 14.4 g of carbon were burned in the presence of
Yanka [14]

Answer:

Mass of carbon dioxide produced = 52.8 g

Explanation:

Given data:

Mass of carbon react = 14.4 g

Mass of oxygen = 56.5 g

Mass of oxygen left = 18.1 g

Mass of carbon dioxide produced = ?

Solution:

C + O₂     →      CO₂

Number of moles of C:

Number of moles = mass/ molar mass

Number of moles = 14.4 g/ 12 g/mol

Number of moles = 1.2 mol

18.1 g of oxygen left it means carbon is limiting reactant.

Now we will compare the moles of C with CO₂.

                       C             :         CO₂

                        1             :          1

                      1.2           :          1.2

Mass of CO₂:

Mass = number of moles × molar mass

Mass = 1.2  mol × 44 g/mol

Mass = 52.8 g
