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 herbert
Explanation:
cause he did not do any of the safety precautions and he was prob not listening to the teacher
The answer should be its kinetic energy increases.
The kinetic energy of a particle means how fast they move, the faster they move, the more kenetic energy they have. In addition, when it moves faster and have more kenetic energy, their temperature becomes higher too.
Therefore, the answer is the first one.
