Answer:
Explanation:
2NO3, Ca2+
Spectator ions exists in both sides of the equation. These ions are present in both sides thus cancel out (they do not contribute to reaction...i.e. they only watch or spectate ;) )
Answer: The solubility of this compound in pure water is 0.012 M
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The equation for the ionization of the is given as:
By stoichiometry of the reaction:
1 mole of
gives 1 mole of
and 2 mole of
When the solubility of
is S moles/liter, then the solubility of
will be S moles\liter and solubility of
will be 2S moles/liter.
![6.5\times 10^{-6}=[S][2S]^2](https://tex.z-dn.net/?f=6.5%5Ctimes%2010%5E%7B-6%7D%3D%5BS%5D%5B2S%5D%5E2)
Thus solubility of this compound in pure water is 0.012 M
Answer:
Viscosity increases with stronger intermolecular forces
Step-by-step explanation:
<em>Viscosity</em> is the resistance of a liquid to flow.
A liquid can flow easily only if the molecules can move past each other with little resistance.
If there are strong intermolecular attractive forces among molecules, it is more difficult for them to move past each other.
For example, the molecules in molasses have strong attractive forces, so it is quite viscous.

Answer : The Product are the new substances that are created following a chemical reactions.
Explanation :
Chemical reaction : A chemical reaction occur when two or more reactants react to form a new substance.
Reactant : A substance that is involved in a chemical reaction.
Product : A new substance that is formed in a chemical reaction.
For example : 
In this, A and B are the reactants and AB is the product.
Therefore, the answer is Product.
