Answer:
The less mass in a given volume of air the less dense the air is going to be.
Answer:
2160 times 4 would be the answer
Explanation:
Took it
Answer:
For sulfur there are two atoms and for oxygen there are 6 atoms.
Explanation:
Sulfur = 2×(1)
= 2 atoms
Oxygen = 2×(3)
=6 atoms

Answer:</h3>
The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.
<h3>
Explanation:</h3>
<u>We are given;</u>
C₂H₄ + 3O₂ → 2H₂O + 2CO₂
We need to ask ourselves the following questions;
Is the equation balanced?
- Yes, the equation because the number of atoms of each element is equal on both sides of the equation.
- That is; Reactants: 2 carbon atoms, 4 hydrogen atoms and 6 oxygen atoms.
- Products: 2 carbon atoms, 4 hydrogen atoms and 6 oxygen
What is the law of conservation of mass?
- According to the law of conservation of mass, the mass of reactants should always be equal to the mass of the products in chemical reactions.
What makes the equation obey the law of conservation of mass?
- For an equation to obey the law of conservation of mass, it must be balanced.
- In this case, <u>the equation given is already balanced and therefore obeys the law of conservation of mass</u>.
1. hydrogen, 2. helium, 3. lithium, 4. beryllium, 5. boron, 6. carbon, 7. nitrogen, 8. oxygen, 9. fluorine, 10. neon
