Given: + _NO +___H₂O ___NH3 + ___O2 -- --> ___NO How many moles of ammonia (NH3) are required to produce 78.0g of water?

A solid has a solubility at room temperature of 78 grams per liter. If 1.0 L of a heated solution containing 100. g of solute is cooled to room temperature, how much solid is formed?

A barium hydroxide solution is prepared by dissolving 3.22 g of Ba(OH), in water to make 58.1 mL of solution. What is the concentration of the solution in units of molarity? concentration: The barium hydroxide solution is used to titrate a perchloric acid solution of unknown concentration. Write a balanced chemica equation to represent the reaction between barium hydroxide and perchloric acid. chemical equation: If 18.5 ml of the barium hydroxide solution was needed to neutralize a 8.04 mL aliquot of the perchloric acid solution, what is the concentration of the acid? concentration:

3KOH+H3PO4⟶K3PO4+3H2O what mass of phosphoric acid in grams is needed to produce 2.15 mol of water?

If 3.00 grams of KCl are initially dissolved in 30.00 mL of water, what is the solubility in grams of solute per 100.0 grams of water?

If 230 mL of H2O is added to 20.0 mL of 12 M HCl, what is the final concentration of the solution?

ds NURSE IN THE MAKING M OF THE MOST COMMON TIONS SEEN ON THE NCLEX ! TUL O SIMPLE REACTIONS Predicting the products of dissolution The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H₂O). -6 Note: "major" chemical species are those present in concentrations greater than 10 compound iron(III) bromide sodium cyanide sucrose Explanation TUL formula FeBr3 Na CN C12H22011 Check TUL Last 4 secil 7594 TXDP Priven 24 major species present when dissolved in water 0 Cera 0 0 pu Welona You got this !!! 5 Carlos de linn SalesAssets@vivint.com com X mol/L. 0₁ 5…

A student dissolves 40.0 mg of lithium phosphate in enough water to make 250.0 mL of solution. What is the concentration of phosphate ions in solution in mEq/L?

Consider 5.6 mg of sucrose dissolved in water. Identify solute and solvent. Sucrose: Solvent: Which is solvent, which is solute?

O Chemical Reactions Solving for a reactant in solution 0/5 Bis One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with iron(II) chloride, which would react with silver nitrate solution like this: FeCl2(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Fe(NO3)2(aq) The chemist adds 72.0 mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 5.9 mg of silver chloride. Calculate the concentration of iron(II) chloride contaminant in the original groundwater sample. Round your answer to 2 significant digits. mg X 5
