Identify the following chemical equations by type.
1. If an electric discharge produces 500 cm3 of ozone (O3), how many cm3 of oxygen (O2) are required?
3O2(g) ---> 2O3(g)
2. When 2.75 dm3 of O2 react with an excess of glucose (C6H12O2), according to the reaction below, what volume of carbon dioxide will be produced?
6O2(g) + C6H12O6(s) ---> 6H2O(g) + 6CO2(g)
3. If an excess of nitrogen gas reacts with 25.0 L of hydrogen gas, according to the reaction below, how many L of ammonia will be produced?
N2(g) + 3H2(g) ---> 2NH3(g)
4. How many cm3 of oxygen would be required to react comp
1. If an electric discharge produces 500 cm3 of ozone (O3), how many cm3 of oxygen (O2) are required?
3O2(g) ---> 2O3(g)
This is a synthesis. Since these are gases we can use cc as if they were mols.
500 cc O3 x (3 mols O2/2 mols O3) = 5-- x 3/2 = ?
#2 and #3 are worked the same way as #1.
#2 is combustion.
#3 is synthesis
#4 doesn't make sense to me.
Answers;
1.
(500 cm^3 O3)*(3 moles O2/2 moles O3) = 500*(3/2) cm^3 O2 = 750 cm^3 O2
2)
(2.75 dm3 O2) x (6 dm3 CO2 / 6 dm3 O2) = 2.75 dm3 CO2
3)
(25.0 L H2) x (2 L NH3 / 3 L H2) = 16.7 L NH3
4)
(250.0 cm3 H2) x (2 cm3 H2 / 1 cm3 O2) = 500.0 cm3 O2
To identify the types of chemical equations given, we need to analyze the reactions and determine the types based on their characteristics.
1. The equation provided is:
3O2(g) ---> 2O3(g)
This is a synthesis reaction, also known as a combination reaction, where two or more substances combine to form a single product. In this case, oxygen gas (O2) molecules react to form ozone molecules (O3).
2. The equation provided is:
6O2(g) + C6H12O6(s) ---> 6H2O(g) + 6CO2(g)
This is a combustion reaction, where a substance reacts with oxygen to produce carbon dioxide and water. In this case, glucose (C6H12O6) reacts with oxygen gas (O2) to produce carbon dioxide (CO2) and water (H2O).
3. The equation provided is:
N2(g) + 3H2(g) ---> 2NH3(g)
This is a synthesis reaction, similar to the first example, where nitrogen gas (N2) reacts with hydrogen gas (H2) to produce ammonia gas (NH3).
4. The question doesn't provide an equation, but if we assume it is related to the previous examples, let's use the combustion reaction as an example equation:
C6H12O6(s) + 6O2(g) ---> 6CO2(g) + 6H2O(g)
To determine the amount of oxygen required to react completely with a certain amount of a given substance, we need to use stoichiometry and ratios from the balanced equation. The coefficients in the balanced equation represent the mole ratios between reactants and products.
Assuming we are given the amount of glucose (C6H12O6) in moles, we can use the stoichiometric ratio between glucose and oxygen to find the amount of oxygen required. Using the coefficient ratio of 1 mole C6H12O6 to 6 moles O2, we can calculate the required amount.
Please provide the necessary information to solve this specific question related to oxygen volume required to react with a substance.
