Explanation:
2 Atom of Hydrogen are present in 2 (NaHCO3)
Answer:
molecular weight of C12H22O11 or grams This compound is also known as Lactose or Sucrose or Maltose. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles C12H22O11, or 342.29648 grams.
Explanation:
Answer:
the heat given off is 75 J.
Explanation:
Given;
latent heat of fusion of lead, L= 25 J/g
mass of liquid lead, m = 3.0g
The heat given off is calculated as;
H = Lm
Where;
H is the quantity of heat given off
H = 25 x 3
H = 75 J.
Therefore, the heat given off is 75 J.
Based on the bond length, the molecular weight of the unknown metal X is 23.
<h3>What are ionic compounds?</h3>
Ionic compounds are compounds which are formed between oppositely charged ions.
When hydrogen combines with the group 1 metals, they form ionic compounds.
The group one metals that combine with hydrogen to firm ionic bonds include:
- Lithium to give Lithium hydride with equilibrium bond length of 0.239Å.
- Sodium to give sodium hydride with equilibrium bond length of 1.896Å.
- Potassium to give potassium hydride with equilibrium bond length of 2.321Å
The molecular weight of lithium is 7 g
The molecularweight of sodium is 23
The molecular weight of Potassium is 39.
Therefore, based on the equilibrium bond length, the molecular weight of the unknown metal X is 23.
