A student measured the pH of solutions if hydrochloric acid and ethanoic acid. Both solutions had the same volume and concentration. The pH of hydrochloric acid was 1.0. The pH of ethanoic acid was 2.9.
The hydrogen ion, H+(aq), concentration of hydrochloric acid was 0.1 mol/dm^3.
The student estimated the hydrogen ion concentration of ethanoic acid.
Which estimate is approximately correct?
A. 0.001 mol/dm^3
B. 0.01 mol/dm^3
C. 0.1 mol/dm^3
D. 1 mol/dm^3

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. type your answer here. (score for question 4: of 5 points) make a general statement about the reactivity of the metals in this experiment. type your answer here.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
