0.95g/mL because you simply divide 155g by 163mL
Answer:
he important thing to notice is that ammonium sulfate contains 2 nitrogen atoms, each belonging to one ammonium ion, NH+4 . So, the molar mass of ammonium sulfate is 132.14 g/mol and the molar mass of nitrogen is 14.007 g/mol.
Explanation:
The freezing point of the solvent in a solution changes as the concentration of the solute in the solution changes (but it does not depend on the identity of either the solvent or the solute(s) particles (kind, size or charge) in the solution).
Generally, pressures lower than 1 atmosphere lower the temperature at which a substance freezes, but for water, a higher pressure gives a lower freezing point. The force from a pressure change figures into the molecular forces already at play in a substance.
Answer:
The answer is 6 valance electrons because it is oxygen and oxygen needs two more electrons to be a noble gas
Explanation:
Hydrogen gas
Explanation:
Expression:
CO₂ + H₂ → CO + H₂O
Hydrogen gas in this reaction is oxidized in the reaction.
In this manner, it is the reducing agent in the reaction.
A reducing agent is the specie in a chemical reaction that undergoes the process of oxidation.
It is marked by:
- Addition of oxygen to a specie
- Removal of hydrogen from a specie
- Loss of electron by an atom
- Increase in oxidation number
- Increase in number of electronegative atoms surrounding a specie.
Here we see that H₂ fits this criteria perfectly well.
CO₂ is the one reduced.
