Answer:
The molar mass of Mg(NO₃)₂, 148.3 g/mol.
Explanation:
Step 1: Given data
- Mass of Mg(NO₃)₂ (solute): 42.0 g
- Volume of solution: 259 mL = 0.259 L
Step 2: Calculate the moles of solute
To calculate the moles of solute, we need to know the molar mass of Mg(NO₃)₂, 148.3 g/mol.
42.0 g × 1 mol/148.3 g = 0.283 mol
Step 3: Calculate the molarity of the solution
M = moles of solute / liters of solution
M = 0.283 mol / 0.259 L
M = 1.09 M
The answer is transition metals because they have no specific charge except for 1 or 2 of them

Answer:
Unbalanced
Explanation:
The reaction equation is given as:
H₂ + O₂ → 2H₂O
The given reaction flouts the law of conservation of mass and it is not balanced. To know a reaction that is balanced, the number of atoms on both sides of the expression must be the same;
Number of moles
Reactants Products
Hydrogen 2 4
Oxygen 2 2
We see that the hydrogen atoms are not balanced.
Magnesium phosphite maybe
