Фосфорную кислоту можно получить, к примеру, взаимодействием оксида фосфора (V) и воды:
P2O5 + 3H2O — 2H3PO4

Оксид фосфора можно получить с помощью взаимодействия фосфора и кислорода:
4P + 5O2 — 2P2O5

Воду можно получить с помощью взаимодействия водорода и кислорода:
2H2 + O2 — 2H2O

Оксид меди (II) можно получить при окислении меди:

Today, I went to the beach front with my children. I found a sea shell and gave it to my 4 year old daughter and said "You can hear the ocean if you put this to your ear." She put the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back!
