Answer:
1.2 mol.
Explanation:
- We can calculate the number of moles of a substance using the relation:
n = mass / molar mass
n is the number of moles.
m is the mass in g <em>(m of NO = 35.0 g)</em>
Molar mass NO = 30.01 g/mol.
- n = mass / molar mass = (35.0 g) / (30.01 g/mol) = 1.166 mol ≅ 1.2 mol.
Answer:
seven litres i
i.e three litres plus four litres
Answer:
Cations are positively charged atoms and hence we need to make the atom positively charged in order to get a cation
We know that an atom is neutral as a whole, so we have equal number of electrons and protons
since we cannot mess with the number of protons in an atom, we have to do it by altering the number of electrons
If we reduce the amount of electrons in an atom, the net charge will be positive and hence a cation will be formed
Answer:
mixture
Explanation:
The properties of the components of substance are different. One component has magnetic properties, another does not. So, we have at least 2 individual substances that were mixed together. So, we have a mixture.
