Answer : The mass of arsenic present in 5.0 g of orpiment is, 1.5 grams.
Explanation : Given,
Mass of orpiment = 5.0 g
As we know that the molar mass of 
is, 246.02 g/mol and the molar mass of As is, 75 g/mol.
As per the question, we conclude that:
As, 246.02 g of contains mass of arsenic = 75 g
So, 5.0 g of contains mass of arsenic = 
Thus, the mass of arsenic present in 5.0 g of orpiment is, 1.5 grams.
Answer:
d
Explanation:
the answer because decomposition means breaking down or taking apart
It can be disproven by philosophy and religion.
Explanation:
The total mass of the product will also be 20g because in chemical reactions, mass is always conserved.
According to the law of conservation of mass "the law states that matter can neither be created nor destroyed but changed from one form to another in a chemical reaction".
- The law simply postulates that mass is conserved in chemical reactions.
- If the mass of reactants is 20g, the mass of the products will likewise be 20g.
- So, the mass is the same in both directions.
Answer:
bacteria
