Question

В каком количестве молекул H3PO4 содержится 15 атомов водорода? 2) в каком количестве молекул P4O10 содержится 30 атомов кислорода ПОМОГИТЕ ОТВЕТИТЬ ПОЖАЛУЙСТА)

Answer 1

1)5.

2)3.

Если я правильно понимаю то так

Answer 2

Number of Hydrogen Atoms in H3PO4

To determine the number of hydrogen atoms in H3PO4 (phosphoric acid), we need to consider the chemical formula of the compound. In H3PO4, there are three hydrogen atoms.

Therefore, the number of hydrogen atoms in one molecule of H3PO4 is 3.

Number of Oxygen Atoms in P4O10

To determine the number of oxygen atoms in P4O10 (tetraphosphorus decoxide), we need to consider the chemical formula of the compound. In P4O10, there are ten oxygen atoms.

Therefore, the number of oxygen atoms in one molecule of P4O10 is 10.
