You have a solution of a weak base, the pH of which is 10.7532. If 10.000 mL of this solution will neutralize 6.655 mL of 0.07667 M HCl, what are the Ka of the base and its original concentration?

If a salt falls on the ground and mix with sand how can it be separated without wasting?

What is the molar mass of KCl?

Na2SO4 * xH2O, the hydrated salt is overheated and the anhydrous salt thermally decompose, one product being a gas; will the reported value of "x" be too high, too low on the unaffected? explain

Can you please help me balance this equation?Na[sub]3[/sub]PO[sub]4[/sub]& + Ba(NO[sub]3[/sub])[sub]2[/sub] = Ba[sub]3[/sub](PO[sub]4[/sub])[sub]2[/sub]& + NaNO[sub]3[/sub]

Sodium metal is so soft that it can be cut with a knife. You cut a perfect cube of sodium with an edge length of 0.5375 cm. If 68% of the cube’s volume contains sodium atoms, how many sodium atoms are in this cube? What is the mass, in grams, of sodium present in the cube? (density of sodium = 0.97 g/cm[sup]3[/sup])

Three isotopes of oxygen are oxygen-16, oxygen-17, and oxygen-18. Write the symbol for each, including the atomic number and mas number.

A new grill has a mass of 30.0 kg. You put 2.0 kg of charcoal in the grill. You burn all the charcoal and the grill has a mass of 30.0 kg. What is the mass in kg of the gases given off? (assume that the charcoal is pure carbon solid and that it burns completely in oxygen).
