Question:is only available as an aqueous solution and contains a halogen. i have a list of 20 chemicals to choose from. water, sodium chloride, sulfuric acid, hydrochloric acid, nitric acid, ammonium hydroxide, sodium hydroxide, oxygen, iron, hydrogen peroxide, pentane, sodium acetate, copper(II) sulfate pentahydrate, calcium carbonate, potassium nitrate, ethanol, acetone, acetic acid, ascorbic acid, iodine.

Answers:hydrochloric acid acid means it is in water and Cl is a halogen

Question:Ok, so i need the equation as a formula, balanced and type: Magnesium + oxygen ---> Aluminum + hydrochloric Acid ---> Sodium oxide + sulfur dioxide ---> Phosphoric acid ---> sodium chlorate ---> sulfuric acid + potassium hydroxide ---> Aluminum sulfate + calcium hydroxide ---> barium carbonate + hydrochloric acid ---> silver acetate + potassium chromate ---> ammonium phosphate + barium hydroxide ---> ***Sorry i now its alot but trust me i have had to do 78 others and these were the ones i was stuck on... so please help... thatnks

Answers:2Mg + O2 --> 2MgO H3PO4 --> 3H+ + PO4^-3 (NH4)3(PO4) + 3Ba(OH)2 --> Ba3(PO4)2 + 3NH4OH I hope this helps - sorry I only chose three

Question:Use appropriate ionic and molecular formulas to show the reactants and the products for the following, each of which occurs in aqueous solutions except as indicated. Omit formulas for any ionic or molecular species that remain (write the net ionic equation). 1. Solutions of silver nitrate and lithium bromide are mixed. 2. Excess hydrochloric acid solution is added to a solution of potassium sulfite 3. solutions of sodium flouride and dilute hydrochloric acid are mixed. 4. A saturated solution of barium hydroxide is mixed with a solution of iron (II) sulfate. 5. A solution of ammonium sulfate is added to a potassium hydroxide solution.

Answers:1. Ag+(aq) + Br-(aq) -> AgBr(s) 2. 2H+(aq) + SO3(2-)(aq) -> H2O(l) + SO2(g) 3. not sure, I think there's no reaction. 4. Ba2+(aq) + SO4(2-)(aq) -> BaSO4(s) 5. NH4(+)(aq) + OH-(aq) -> NH3(g) + H2O(l)

Hydrogen Peroxide Titration

The decomposition of hydrogen peroxide is problematic because the concentration of its solutions may go down significantly during storage. In this video, we perform a titration with potassium permanganate and sulfuric acid in order to calculate its concentration. The reaction formula is:...
