If the water in your well has 1000.0 mg/L of calcium carbonate dissolved in it, How many grams of sodium oxalate could you mix with 100.0 mL of that water before a precipitate would form
What is the molarity of a solution made by dissolving .34 moles of NaCl in 455 mL of water?
The reaction: 2 HI → H2 + I2, is second order and the rate constant at 800 K is 9.70 × 10-2 M-1 s-1. How long will it take for 8.00 × 10-2 mol/L of HI to decrease to one-fourth of its initial concentration.
Given mass of a gas 0.26g, pressure is 763mmHg and volume of 147mL.by using an ideal gas law calculate the molar mass of the gas
When 0.0172 mol HI is heated to 500 K in a 2 L sealed container, the resulting equilibrium mixture contains 1.9 g of HI. Calculate Kc for the decomposition reaction 2HI(g) *) H2(g) + I2(g) .
1) Why does a glycogen molecule have one reducing end?, From the abbreviated name of the compound galactosyl (alpha beta 1 -->1) glucose we know that,
Calculate the pressure in the flask in atmospheres and torr also If the sealed-tube manometer in had a height difference of 20.0 inches between the Hg levels?
There are very few compounds that contain an element from the noble gas family (elements in column 18, rightmost column). Explain why there are so few noble gas compounds in nature.
When hydrochloric acid reacts with magnesium metal, hydrogen gas and aqueous magnesium chloride are formed.
explain why it is appropriate to group a polyatomic ion in parentheses in a chemical formula, if more than one of that ion is present in the formula.
If a reaction mixture initially contains 0.159 M SO2Cl2 , what is the equilibrium concentration of Cl2 at 227 C?
Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.
A student has invented a new temperature scale, the Zuban scale ,In common with the Celsius, Kelvin and Fahrenheit scales, it is a linear scale.
