I think the correct answer would be direct additives. Not proper handling of cleaning agents especially in areas where food are prepared or served would most likely add chemicals to the food which is harmful to the consumer. Hope this helps.
Because the reactants react with each other and chemically react to produce a different product like with fire when it reacts with the wood it burns and the product left behind is a new different substance from the reactants in this case the product is ash
Answer:
The percent yield is 66.7%
Explanation:
1. The balanced chemical reaction to obtain carbon dioxide from the methane is:
2. Calculathe the theoretical quantity of carbon dioxide.
As the problem says that the limiting reagent is the methane, all the calculations will be made from this quantity:
3. Calculate the percent yield:
Percent yield = 
Percent yield = 
Percent yield = 66.7%
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.
