C2H4(g)+CO2(g)+H2O(g)
interpret the equation in terms of relative numbers of moles,volumes of gas at STP,and masses of reactants and products.
You don't have an arrow; therefore, no one can tell what is a product and what is a reactant. The "so-called" equation means
1 mol C2H4 (28 grams), 1 mol H2O(18 grams) and 1 mol O2(32 grams). 1 mol of a gas occupies 22.4L at STP.
To interpret the given equation in terms of relative numbers of moles, volumes of gas at STP, and masses of reactants and products, we will look at the balanced chemical equation:
C2H4(g) + CO2(g) + H2O(g)
1. Relative Numbers of Moles:
The coefficients in the balanced equation represent the relative numbers of moles. From the equation, we can see that:
- 1 mole of C2H4 reacts with 1 mole of CO2 and 1 mole of H2O.
2. Volumes of Gas at STP:
The molar volume of an ideal gas at Standard Temperature and Pressure (STP) is 22.4 liters.
- Based on the coefficients in the equation, we can say that:
- 1 mole of any gas will occupy a volume of 22.4 liters at STP.
- So, 1 mole of C2H4, 1 mole of CO2, and 1 mole of H2O will each occupy a volume of 22.4 liters at STP.
3. Masses of Reactants and Products:
To determine the masses of reactants and products, the molar masses of the compounds involved are required.
- Carbon (C) has a molar mass of 12.01 g/mol.
- Hydrogen (H) has a molar mass of 1.008 g/mol.
- Oxygen (O) has a molar mass of 16.00 g/mol.
Using these molar masses, you can calculate the mass of each reactant and product based on the moles involved in the equation.
To interpret the given chemical equation in terms of relative numbers of moles, volumes of gas at STP, and masses of reactants and products, we need to analyze the balanced equation.
The balanced equation is:
C2H4(g) + CO2(g) + H2O(g)
Relative Numbers of Moles:
From the balanced equation, we can determine the stoichiometric coefficients, which represent the relative numbers of moles of each compound involved in the reaction. In this equation, we have:
- 1 mole of C2H4
- 1 mole of CO2
- 1 mole of H2O
Volumes of Gas at STP:
At standard temperature and pressure (STP), 1 mole of an ideal gas occupies 22.4 liters. So, if we know the number of moles, we can calculate the volumes of gases at STP using the conversion factor of 22.4 liters per mole.
Masses of Reactants and Products:
To determine the masses of reactants and products, we need to know the molar mass of each substance. The molar mass is the mass of 1 mole of a substance, expressed in grams per mole. By multiplying the number of moles by the molar mass, we can calculate the masses of reactants and products. The molar masses for C2H4, CO2, and H2O can be obtained from the periodic table.
It's important to note that the information provided in the equation alone is not sufficient to calculate the specific masses or volumes, as we would need additional information such as the amounts of the substances involved. However, understanding the relationship between moles, volumes, and masses allows us to convert between these units and make calculations based on given information.
