Magnesium hydroxide is used in several antacid formulations. When it is added to water it dissociates into magnesium and hydroxide ions.
Mg(OH)2(s) Picture Mg2+(aq) + 2OH¯(aq)
The equilibrium constant at 25°C is 8.9 × 10¯12. One hundred grams of magnesium hydroxide is added to 1.00 L of water and equilibrium is established. What happens to the solution if another 10 grams of Mg(OH)2 are now added to the mixture?
Compare the properties of elements and compounds. Give two examples of each, including one example that exists in the human body. Explain the atomic nature of one element and one compound found in human body.
NaOH solution is used to determine the amount of Mg(OH)2 in a sample of milk of magnesia, (molairty of NaOH is 1.172M). A 10.0 gram sample of milk of magnesia is required with 8.00 mL of 6.00 M HCl.
A sample of oxygen gas has a volume of 3.34l at 21 c . what volume will it occupy at 144 F if the pressure and number of mol are constant
The final temperature of the calorimeter is 150°F. What is the mass of titanium used? The specific heat capacity of water is 4.184 J g-1 °C-1.
The oxidation of hyrogen by oxygen is one of the most-used reactions in fuel-cell technology. The overall reaction, which is given below, has a (Delta)G^o value of -474 kJ/mol.
Put in order the following molecules in terms of the Permeability of the molecule across a membrane by simple diffusion at pH 7.
If 8.88 X 10^7 aluminum atoms can fit along a 1.00 inch line, what is the diameter of a single aluminum atom?
When 2.00 g of NaOH is added to 50.0 ml of 1.0 M HCl solution in a constant pressure calorimeter, the temperature increased by 13.1oC. Calculate the heat of neutralization in KJ/mol
Compute the molecular formula of CH 3 COOH the percent composition of acetic acid is 39.99% C and 6.73% H. The remainder of the compound is oxygen.(The molar mass of acetic acid is 60.06 g/mol.)
how did rutherford interpret the observation that only a very few of the a particles were scattered by the gold foil
Assume you dissolve .378 g of the weak acid benzoic acid in enough water to make 1.00e2 ml of solution and then titrate the solution with .200 M NaOH.
What is the equilibrium concentration of I2, Br2, and IBr? If you could show each step you do to solve for x that would be great.
