Mixing sodium chloride and water is a physical change. The chemical composition of the sodium chloride (NaCl) remains the same in the solution, the sodium chloride molecules are simply dispersed in the water. The change is reversible and does not involve a chemical reaction.

A pure and fresh solution of silver nitrate is clear.
The chemical formula for silver nitrate is AgNO3.
The reaction between calcium (Ca) and silver nitrate (AgNO3) is not spontaneous under standard conditions since it does not occur without outside intervention. It is thermodynamically unfavorable as the standard Gibbs free energy change for the reaction is positive.
The chemical formula for silver nitrate is AgNO3.
To find the mass of silver in 3.4g of AgNO3, you need to consider the molar mass of AgNO3. The molar mass of AgNO3 is 169.87 g/mol. From this, you can calculate the mass of silver (Ag) in AgNO3, which is 107.87 g/mol. Therefore, the mass of silver in 3.4g of AgNO3 is (107.87/169.87) * 3.4g.
To find the mass of silver in 3.4g of AgNO3, you need to consider the molar mass of silver nitrate (AgNO3). The molar mass of AgNO3 is 169.87 g/mol. Since the molar ratio of Ag to AgNO3 is 1:1, the mass of silver in 3.4g of AgNO3 would be 3.4g * (1/169.87) ≈ 0.02g.
AgNO3 powder is white but a little grey solid.
To find the number of moles, you need to divide the given mass (85 grams) by the molar mass of AgNO3 (169.87 g/mol). 85 grams of AgNO3 represents 0.500 moles.
The correct formula for silver (I) nitrate is AgNO3.
Silver nitrate (AgNO3) is composed of 63.5% silver by mass.
