What are the rules to determine the solubility of salts?

Chemistry
1. How many molecules does 36.0 grams of water represent? Change the following masses to number of particles by: A) dividing by the molar mass to get the number of moles, and then B) multiplying number of moles by Avogadros number

Chemistry
Identify which element is being oxidized and which is being reduced Mg (s) + 2H2O (g) = Mg(OH)2 (s) + H2 (g)

Geometry
A spherical water tank has a diameter of 10 feet. How much water does it hold when half full ? ( use 3.14 )

Chemistry
Predict the characteristic of the solutions of the following salts. 1.CrBr3 2.NH4ClO4 3.NaCl 4.NiSO4 5.GaI3 6.MgC4H4O5 7.K2CO3

Hi. Do you know of any poems about holidays that include word play or puns? Thanks!

Algebra 2
If f(x)= x^2 + 3 and g(x) = 3x - 1 then find the following: 1a. (f+g)(x) 1b. (f+g)(3) 1c. (f-g)(x) 1d. (fg)(x) 1e. (fg)(-1) 1f. (f/g)(x) 1g. (f o g)(x) 1h. (f o g)(1) 1i. (g o f)(x)

physics
A 3.00x10^-3 kg lead bullet enters a target with a speed of 2.00x10^2 m/s and comes to rest within the target. Calculate the rise in temperature of the bullet assuming that 80.0% of the heat produced is absorbed by the bullet. The Specific heat of lead is 1.30x10^2 J/kg K
