It would be the needle pressure gage temp check
Answer:
Heat causes the molecules to move faster (heat energy is converted to kinetic energy), which means that the volume of a solid or a liquid. ... The particles in the air do not have more kinetic energy than particles in the mercury, because they are the same.
Explanation:
I hope this help you!
Answer: Small molecular structure
Explanation:
> Bromine and Hydrogen are both non-metals, so they hence cannot form ionic compounds and metals. As such, Ionic Lattice and Metallic structure is wrong.
> gaseous Hydrogen Bromide HBr is produced. Giant covalent substances, such as diamond, have very high melting and boiling points. As such, HBr is a small molecular structure, or a simple covalent substance.
1 more of water requires 1 mole of hydrogen (H2) and 0.5 moles of oxygen (O2) . This requires 100/18 moles of hydrogen. As the molar mass of hydrogen is, 2 it requires 200/18= 100/9 g of hydrogen.
