The number of hydrogen and oxygen atoms that should be in the products according to the law of conservation of matter, is given as follows:
4 hydrogen atoms and 2 oxygen atoms.
<h3>What is stated by the law of conservation of matter?</h3>
The law of conservation of matter states that the amount of matter in the solution remains constant, even when the substance has a change in the format.
The amounts on the equation are given as follows:
- 2 oxygen atoms in the reactants.
The law of conservation of matter states that the amounts remain constant, hence the amounts of the solution are given as follows:
- 2 oxygen atoms in the reactants.

Step-by-step explanation:
Answer:the number of short sleeves shirt sold is 15
the number of long sleeves shirt sold is 5
Step-by-step explanation:
Let x represent the number of short sleeves shirt sold by the student council.
Let y represent the number of long sleeves shirt sold by the student council.
The student council sells short sleeves for $5 each and long sleeve for $6 each. They were sold for a total of $105. This means that
5x + 6y = 105 - - - - - - - - - -1
The total number of shirts sold is 20. This means that
x + y = 20
Substituting x = 20 - y into equation 1, it becomes
5(20 - y) + 6y = 105
100 - 5y + 6y = 105
- 5y + 6y = 105 - 100
y = 5
x = 20 - y = 20 - 5
x = 15
