HELP ME, PLEASE. I REALLY NEED IT NOW add 3.6 grams of mixture A consisting of two carbonate salts of the two successive metals in group IIA to react with the excess HCl acid solution to obtain gas B. Allow all gas B to absorb completely by 3 liters of solution Ca. (OH) 2 0.015M obtained 4 grams of precipitate
Determine the salts in mixture A and calculate the mass% of the salts in A

Order the following from smallest to largest atom, electron, quark, proton, neutron, molecule, nucleus

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments, solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
