I assume there is a typo in the equation. It is H2O instead of H2I.
The ratio of H2 and O2 that react with each other is 2:1. To find out the grams of H2, we need to first find out the moles of O2 and H2.
Moles of O2 = mass of O2/molar mass of O2 = 192g/32g/mol = 6 mol. Therefore, the moles of H2 = 6mol *2 = 12 mol.
So the mass of H2 that reacts with O2 = moles of H2 * molar mass of H2 = 12 mol * 2 g/mol = 24 g
Answer:
Explanation:
1 mole is equal to 1 moles Zinc, or 65.38 grams.
The bonds between the layers are much weaker than covalent bonds. This enables the layers to slide across each other, making graphite soft. Graphite can also conduct electricity, between the layers of carbon atoms. Graphite is used as pencil 'lead'.
Answer:
56 is the mass
Explanation:
You would add 26 and 30(the protons and neutrons). I didn't add the electrons because they are so small their mass is negligible in this situation.
Answer:
It loses an electron and has an octet in the next-lowest energy level
Explanation:
