how would you use silver nitrate reagent to distinguish between tartaric acid and one of its salts?

Solutions consist of a solute dissolved into a solvent, e.g., a salt dissolved in water. There is often a need to quantify how much solute is present per unit solution volume. Concentration is most commonly expressed in terms of molarity (as molar or M), which is the number of moles (mol) per liter (L) of solution. A one molar solution can be expressed as follows:

1 M = 1 mol1 L or 1 molL


Use the PhET simulation to identify what happens to the concentrations of a dilute Drink mix mixture or a pure Drink mix solution for the following scenarios. A pure Drink mix solution can be obtained by draining all the mixture, then adding Drink mix to the container as a Solution (radio button in the upper right area of the simulation). Note that the Concentration meter can be placed toward the bottom of the container or in the stream of the Drink mix.

How much heat is produced by the complete combustion of 218 g of CH4?

Predict and Discuss the Operational troubles that Boiler is expected to suffer if the existing source of water is used as such for the intended purpose? Your discussion should contain Definition of Trouble, Disadvantages and Removal techniques

The LD50 for a substance is the dose that would be lethal for 50% of the population that receive that dose. The LD50 for aspirin in rats is 1.75 grams per kilogram of body weight. How many aspirin tablets, each of which contains 325 mg of aspirin, would you have to feed a rat weighing 290. g to give him this dose?

Answer in units of J.

A beaker containing 250.0 g of water is heated with 1500.0 J of heat energy. If the temperature of the water changed from 22.0000oC to 23.4354oC, what is the specific heat of water?

if you burn carbon with oxygen with a heat of 2050 kj how much mass will the carbon be carbon

A 1.000 cubic centimeter sample of lead (density = 11.34 g/cm3), a 1.000 cubic centimeter sample of glass (density = 2500 kg/m3), and a 1.00 cm3 sample of Ebony wood (density = 960 kg/m3) and Balsa wood (density = 170 kg/m3). You drop each in separate beaker of water each containing 250 mL of water. How do the volumes of water displaced by each sample compare? Explain.
