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). Note: "major" chemical species are those present in concentrations greater than 10 mol/L. -6 compound ammonium bromide glycerol glucose formula NH₂ Br C₂H₂O3 C6H12O6 major species present when dissolved in water 00 X O 0.0.... 3

A chemist samples a river's water to measure the amount of fertilizer runoff from the area farms. In a 0.0740 L sample, the chemist measures 562 µg of nitrate. Express the concentration of nitrate in parts per million (ppm) and parts per billion (ppb). Assume the density of the river water sample is 1.00 g/mL. concentration: concentration: ppm ppb

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 (H,O).

Most biological reactions take place in an aqueous (water-filled) environment. For example, salts like NaCl readily dissolve in water. However, NaCl is not soluble in a solvent like benzene. Based on what you know about the chemistry of water, explain why this is the case.

The density of a solution that is 20.0% HClO4 is 1.138 g/ml. Calclulate the molarity of the HClO4 (molar mass is 100.46 g) solution

A salt has a molar solubility of 4.18 M at 21.0°C. What is the the maximum amount of salt (in moles) that can dissolve in 1.495 L of solution before the solution becomes supersaturated at 21.0°C? Assume the salt has a molar mass of 55.44 g/mol. Report your answer to 2 decimal places.

Sodium carbonate dissociates when it dissolves in water as follows:   If the concentration of the sodium ions is 0.817 mol/L, then what is the concentration of the sodium carbonate solution? Record only your numerical answer with the correct number of significant digits.  You do not need to include units as the units appear for you beside the answer box already.
