A) a saturated solution of metal hydroxide, M(OH)2, has a pH of 10.35. Calculate the molar solubility and the ksp, for this metal hydroxide? M(OH)2(s)<<<<>>>M^2+2OH1- B)What is the molar solubility if this metal hydroxide in 0.10 M M(NO3)2?
The mass of the final solution is 73.0 grams, and its heat capacity is 3.85 J/g°C; the heat capacity of the calorimeter is 5.0 J/°C. Calculate the ?Hreaction in kJ/mol metal.
A 12.0g- sample of a gas has a volume of 5.25g at 28 celcius and 757mmHg If 2.7g of the same gas is added to this constant 5.25L- volume and the temperature raised to 64 celsius, what is the new gas pressure?
Using the same sample of gas ( = 275 , = 43 ), we wish to change the pressure to 2750 with no accompanying change in volume or amount of gas.
