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:
H =2; I = 2; J = 2
Explanation:
Carbon is element 6 in the Periodic Table.
Start at element 1 (H) and count from left to right until you reach element 6 (C).
You get the electron configuration
C: 1s² 2s²2p².
Thus,
H =2; I = 2; J = 2
The mass of iron (III) oxide (Fe2O3) : 85.12 g

The mass
Solution
1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
