1.When 5 grams of wood burns completely and 15 grams of oxygen, 10 grams of water vapor and some carbon dioxide are given off.
(How many grams of carbon dioxide would be produced in this example?)
I need help with the question in parentheses. I have the answers to the rest.
To determine the number of grams of carbon dioxide produced in this example, we need to understand the chemical reaction that occurs when wood burns.
Wood is primarily composed of carbon (C), hydrogen (H), and oxygen (O), while oxygen (O2) is the reactant required for combustion. When wood burns, it reacts with oxygen in the air to produce carbon dioxide (CO2) and water vapor (H2O).
From the given information, we know that 5 grams of wood burns completely and 15 grams of oxygen are consumed during combustion. We are also told that 10 grams of water vapor are produced.
To find the amount of carbon dioxide produced, we need to determine the amount of carbon present in the wood and calculate its conversion to carbon dioxide.
1. Calculate the amount of carbon in the wood:
- Since the wood completely burns, the amount of carbon in the wood would be equal to the mass of the wood itself. In this case, it is 5 grams.
2. Convert the amount of carbon to carbon dioxide:
- The molecular weight of carbon is 12 grams/mol, while the molecular weight of carbon dioxide is 44 grams/mol (12 for carbon and 32 for oxygen).
- To calculate the amount of carbon dioxide produced, we can use the molar ratio between carbon and carbon dioxide, which is 1:1. This means that for every 1 gram of carbon burned, 1 gram of carbon dioxide is produced.
- Therefore, the mass of carbon dioxide produced would also be 5 grams.
Hence, the answer to the question in parentheses is that 5 grams of carbon dioxide would be produced in this example.
