A chemist wants to make aluminum sulfide according to the following reaction: 3(NH4)2S (aq) + 2AI(NO3)3 (aq) ---> Al2S3 (s) + 6NH4NO3 (aq)

If he has an excess of ammonium sulfide and 125.0 mL. of a 1.51 M solution of Al(NO3)3, how many
grams of aluminum sulfide can he make?

Sodium sulfate dissolves as follows: na2so4(s) → 2na+(aq) + so42- (aq). how many moles of na2so4 are required to make 1.0 l of solution in which the na concentration is 0.10 m?

The atomic number, or number, is the described as the number of in the nucleus of an chemical element.

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.
