Identify the ion ratios needed to form neutral compounds from the ions below. The metal ion (cation) is listed first, and the nonmetal ion (anion) is listed second. Make sure to give each ratio in its most simplified form. Na+:Br– = 1 :
Al3+:Cl– = 1 :
Mg2+:O2– = 1 :
Al3+:O2– = 2

What does the mass of 0.7891 mol of ferric oxide (fe2o3)

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.

Which of the following describes qualitative data? a) recording the temperature of a solid as it is warmed. b) noting the color of a solution as it is heated. c) measuring the volume of an object by water displacement. d) taking the mass of an object using a balance.
