Answer: The reactivity of a metal depends on how easily it loses electrons
The reactivity of metals is due to the difference in stability of their electron configurations as atoms and as ions. As they are all metals they will form positive ions when they react.
Answer:
Explanation:
Given data:
Volume of solution = 1.5 L
Mass of solute = 61.2 g
Molar mass of solute:
= 23 + 14 + (16 × 3)
= 23 + 14 + 48
= 85 g/mol
Required:
Molarity = ?
Formula:
Solution:
First, we have to find moles of solute.
We know that,
Moles = mass / molar mass
Moles = 61.2 / 85
Moles = 0.72 moles
Now, finding molarity:
Molarity = 0.72 / 1.5
The molarity of the 1.5 L solution of sodium nitrate containing 61.2 g of NaNO3 is approximately **0.480 M**
To calculate the molarity (M) of a solution, you can use the formula:
- Volume of solution (\( V \)) = 1.5 L
- Mass of sodium nitrate = 61.2 g
- Molar mass of sodium nitrate = 85 g/mol (Na: 23 g/mol, N: 14 g/mol, O: 16 g/mol)
First, calculate the moles of sodium nitrate using its molar mass:
Now, substitute the values into the molarity formula:
So, the molarity of the 1.5 L solution of sodium nitrate containing 61.2 g of NaNO3 is approximately **0.480 M**.

Answer:
c) The mass is the same
Explanation:
According to the Law of Conservation of Mass, the total mass of the reactants in a chemical reaction is always equal to the total mass of the products formed. This means that the total mass of the reactants and the total mass of the products will always be the same.
Water has specific heat. This helps us with homeostasis.
