Shana solves stoichiometry problems using the equation for the synthesis of water. Which interpretation of the balanced equation
2 answers:
Answer : The wrong statement is, Two grams of hydrogen react with one gram of oxygen to form two grams of water.
Explanation :
Synthesis reaction : It is a type of reaction in which the reactants present in elemental state that reacts to give a single product.
It is represented as,
where, X and Y are the reactants and XY is the product.
The balanced synthesis reaction of water will be,
By the stoichiometry we can say that, 2 moles of hydrogen react with 1 mole of oxygen
to form 2 moles of water
as a single product.
Or we can say that,
2 molecules of hydrogen react with 1 molecule of oxygen to form 2 molecules of water.
Or,
2 liters of hydrogen react with 1 liter of oxygen to form 2 liters of water.
These three statements are correct.
But the statement, 2 grams of hydrogen react with 1 gram of oxygen to form 2 grams of water are incorrect statement.
Hence, the wrong statement is, Two grams of hydrogen react with one gram of oxygen to form two grams of water.

Answer : The correct option is, (C) 0.675 M
Explanation :
Using neutralization law,
where,
= concentration of
= 13.5 M
= concentration of diluted solution = ?
= volume of
= 25.0 ml = 0.0250 L
conversion used : (1 L = 1000 mL)
= volume of diluted solution = 0.500 L
Now put all the given values in the above law, we get the concentration of the diluted solution.
Therefore, the concentration of the diluted solution is 0.675 M
