A metal, M, can readily form the M+ cation. A nonmetal, X, is a gas at room temperature and can easily form the X- anion. Write a balanced chemical equation for the reaction that occurs when metal M reacts with nonmetal X. Include state symbols for the reactants and products.
what are the ground state electron configuration of the elements in period 2 of this alternate reality?
calculate the molar change in chemical potential of an ideal gas that expands 10 times of its original vol. at 100k
Calculate the sodium ion concentration when 80.0 mL of 3.2 M sodium carbonate is added to 25.0 mL of 2.3 M sodium bicarbonate.
What is the final temperature of the water when equilibrium is reached? (Assume a density of 0.998 (g/mL) for water.)
A solution contains 0.063g of oxalic acid, H2C2O4*2H2O, in 250 mL. What is the molarity of this solution?
A 250.0ml sample of air at 100.0 K is warmed to 200.0 K at constant pressure. What is the volume of the air sample at the new temperature.
An auto bumper is coated with a layer of chromium, 0.017 cm thick. The bumper has a surface area of 3.43 x 104 cm2. The density of chromium metal is 7.19 g/cm3. How many atoms of chromium are used in the coating?
Explain why recrystallization, as a general technique, is usually effective at removing a few percent of impurity, even though the solubility (g/mL) of the impurity might be similar to that of the main component.
When 1 mol of glucose is burned, 2802.5 KJ of energy is released. Calculate the quantity of energy released to a person by eating 5.00g of glucose in a candy.
