Answer:
8 atoms of oxygen.
Explanation:
Given parameter:
Mass of magnesium phosphate = 15g
Unknown:
Number of oxygen atoms = ?
Solution:
The formula of the compound is;
Mg₃(PO₄)₂;
Number of atoms oxygen = 2(4) = 8 atoms of oxygen.
Answer:
1.D) CH4 + 2O2 → CO2 + 2H2O
2C)2,1,2
3.D)SIO2 + 4HF → SIF4 + 2H2O
4.D)2As + 6NaOH → 2Na3AsO3 + 3H2
5.C)SiCI4 + 2H2O → SiO2 + 4HCI
Explanation:
equal number of atoms of each elements in both the sides of the chemical equation is required to have an equation in balanced state.
Hey there!
Molarity = 4.8/850 x 1000 =5.647mol/lit or 5.65M
Hope this helps you dear :)
Have a good day :)
