Question

1. where does the matter from burning propane come from? when propane burns, water vapor and carbon dioxide forms. where does the water vapor and carbon dioxide come from? select true or false for the following statements: t f some water vapor and carbon dioxide comes from the person who burns the propane t f some water vapor and carbon dioxide comes from the propane t f some water vapor and carbon dioxide is created by the propane t f some water vapor and carbon dioxide comes from the air explain your choices. where does the water vapor and carbon dioxide from the propane come from?

Explanation:

Propane ($C_3H_8$) is a hydrocarbon. When it burns in the presence of oxygen ($O_2$), it undergoes a combustion reaction. The carbon in propane combines with oxygen from the air to form carbon - dioxide ($CO_2$), and the hydrogen in propane combines with oxygen to form water vapor ($H_2O$). So, carbon - dioxide and water vapor are created by the propane during combustion, not coming from the person burning it or from the air in terms of the main source of their elements within the reaction context.

Answer:

1. F: Some water vapor and carbon dioxide comes from the person who burns the propane - False. The person is not the source of the elements in water vapor and carbon dioxide from propane combustion.
2. T: Some water vapor and carbon dioxide comes from the propane - True. The hydrogen and carbon in propane react to form these products.
3. T: Some water vapor and carbon dioxide is created by the propane - True. Through the combustion reaction of propane with oxygen.
4. F: Some water vapor and carbon dioxide comes from the air - False. While oxygen comes from the air for the combustion, the carbon in carbon - dioxide and hydrogen in water vapor mainly come from propane.

The matter from burning propane comes from the propane itself and the oxygen from the air that it reacts with. The carbon - containing part of the products (carbon dioxide) comes from the carbon in propane, and the hydrogen - containing part (water vapor) comes from the hydrogen in propane, with oxygen from the air combining with these elements during combustion.
