Answer: Option (4) is the correct answer.
Explanation:
It is known that density is mass divided by volume.
Mathematically, Density =
Since, density is directly proportional to mass. So, more is the mass of an element more will be its density.
Mass of magnesium is 24.305 g/mol.
Mass of barium is 137.327 g/mol.
Mass of beryllium is 9.012 g/mol
Mass of radium is 226 g/mol.
Hence, radium has more mass therefore it will have the greatest density at STP.
Explanation:
The reaction between calcium hydroxide and nitric acid is as follows.
Number of reactant atoms are as follows.
- Ca = 1
- O = 4
- H = 3
- N = 1
Number of product atoms are as follows.
- Ca = 1
- O = 4
- H = 2
- N = 3
To balance the given chemical equation, multiply by 2 on reactant side and multiply
by 2 on the product side.
Therefore, the balanced chemical equation will be as follows.
