Answer:
A. It shows the same number of atoms of each element on both sides of the equation.
Explanation:
A balanced chemical equation demonstrates the conservation of matter by showing the number of atoms of each element on both sides of the equation or expression.
According to the law of conservation of matter, matter is neither created nor destroyed in the course of a chemical reaction but atoms are rearranged.
- Based on this premise, the number of atoms or moles on both sides of the expression must be equal.
- If there are 3 atoms of carbon on one side, the product must also reflect 3 atoms of carbon.
5L O2 x 1 mol O2/ 22.4L O2 x 2 mol H20/ 1 mol O2 x 22.4L H20/ 1 mol H20 = 10 L H2O
For future reference though, since its at STP that means that the coefficient are in proportion. Since oxygen has a coefficient of 1 and water has a coefficient of 2 for every 1 liter of oxygen there is 2 liters of water. Hence you started with 5 liters and ended with 10
Answer: 186.3 g of 
will be produced from 2.50 mol of K
Explanation:
The balanced chemical reaction is:
According to stoichiometry :
2 moles of K produce = 2 moles of
Thus 2.50 moles of 
will produce=
of
Mass of 
Thus 186.3 g of will be produced from 2.50 mol of K
