using the image, explain the structure and formation of hydrated ions.

Part of a routine blood test is to check the level of sodium in your blood. It is optimum to have between 135 and 146 micromoles per milliliter [mumol/mL] of sodium. Having an amount too high or too low can cause a variety of health issues. Sodium has a molecular mass of 23 grams per mole [g/mol]. A blood sample is 2.7 [ml]. Determine the minimum mass of sodium that must be present to surpass the upper optimum limit of 146 micromoles per milliliter [mu mol/mL].

To what volume (in mL) must 60.0 mL of 1.75 M HCl be diluted to produce 0.500 M HCl?

Write and explain step by step. If you are handwriting it make sure its readible.

Write out the chemical equations that are involved for:a) the formation of the salt (give the chemical structure for the salt formed)b) the conversion of the salt back to the original compound

Question 9 A student is attempting to identify the anion in an unknown solid. The student first dissolves the solid in aqueous solution, and then adds aqueous barium nitrate. A solid product forms. The student then adds hydrochloric acid, which causes the solid to dissolve. Which of the following anions might be in this unknown sample? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a Phosphate Nitrate Carbonate d Sulfate e Chloride

What is an electrolyte? A substance that dissolves in water but doesn't produce ions. A substance that dissolves in water and produces ions. A substance that doesn't dissolve in water. A substance that melts at room temperature.

Is the acid-base neutralization reaction between sodium hydroxide and hydrochloric acid an exothermic or endothermic process?

Suppose each student in a laboratory prepares two aqueous solutions, Solution A and Solution B, then measures the conductivity of each. Predict the comparison of conductivity between the two solutions. Solution A contains 1.0 moles of MgCl, Solution B contains 1.0 moles of NaOH Choose... Solution A contains 1.5 moles of CH,06 Solution B contains 1.5 moles of NaCl. Choose... Solution A is 10.0 mL of 0.1 M ethylene glycol. Solution B is 25.0 mL of 0.1 M ethylene glycol. Choose..
