How many grams of Ag₂ CrO4 will precipitate when 86ml of 0.2 molar Ag₂Cro, is added to 500ml of 6.3 molar K₂ CrO4? Molar mass of Ag₂ CrO4 = 331.74 g/mol
Balanced Equation: 2AgNO3 + K₂CrO4 Ag₂ CrO4 + 2KNO3
I am struggling with ionic bonds. If we look at the carbonate compound, we see it consists of 1 carbon atom and 3 oxygen atoms. Yet, it has 2 more electrons than protons and that is what makes it a negative ionic compound. But why does it have TWO more electrons than protons if there are THREE oxygen atoms, contributing ONE electron each? Shouldn't it have THREE more electrons than protons?
what is the symbol for the lithium ion in lithium chloride
i need to make a solution of combined citric acid and sodium citrate in 1 liter distilled water ( CA/SC ) . I am told that i need it to zero mol … i already have the citric acid and the sodium citrate each separately . How many grams to put of each to get a zero mol solution of both ? thank you

What is the pH solution containing 0.30 M HCOOH and 0.52 M HCOOK?Compare your result with the pH of a 0.30 M HCOOH solution
To make a solution, 38.7 g of a nonelectrolyte is dissolved into 218 g of water. The freezing point of the solution is measured to be -5.53°C. Calculate the molar mass of the solute.
A water sample was reported to contain 250 ppm CaCO3. How many grams of CaCO3 is present in 4 liters of water.
When dissolved sodium hydroxide reacts with sulfuric acid, aqueous sodium sulfate, water, and heat are formed.
Salt is often used to melt ice and snow on roads in the winter and the temperature right now is - 4.500°C. How much NaCl ( complete dissociation) would be necessary to melt 1000kg of ice by bringing down the freezing temperature to 4.500°C?
