Al has a 3 + charge, and SO 4 has a 2-charge. So, it takes 3 of the SO 4 anions to balance 2 of the Al cations. So, you get Al 2 (SO 4) 3. Now, for naming this compound, since Al is ONLY 3 + and does not have variable valence, you don't use the (III) in parentheses. The Roman number in parentheses is ONLY used for transition metals that have ...

2021年12月20日 · 2 Al + 3FeSO4 → Al2(SO4)3 + Fe. look at oxidation number (o.n.) for each element on left side and right side of the equation . Al on left is zero. Al on right is 3+. Al has lost electrons so it was oxidized. It is the reducing agent. Fe on the left is 2+. Fe on the right is zero. Fe has gained electrons so it was reduced.

Aluminum sulfate, Al2(SO4)3, is used in styptic pencils to stop minor bleeding. What is the number of atoms in the chemical formula of aluminum sulfate? 17 21 10 O 12 O 14

2020年11月20日 · 2Al(s) + 3H2SO4(aq) ==> Al2(SO4)3(aq) + 3H2(g) ... balanced equation. Using the stoichiometry of the balanced equation (2 mol Al : 3 mol H 2 SO 4) and dimensional analysis, we can find the mass of Al needed to react with 26.5 ml of 0.542 M H2SO4. How many moles H2SO4 are present? 26.5 ml x 1 L/1000 ml x 0.542 mol/L = 0.014363 moles H 2 SO 4

2023年5月24日 · Haroon I. To determine the total concentration of all ions in a solution formed by dissolving 1.50 g of Al2(SO4)3 in 100.0 ml of solution, we need to calculate the moles of Al2(SO4)3 and then determine the concentration of each ion.

Question: Al2(SO4)3(aq)+AgNO3(aq)? Express your answer as a chemical equation. Enter NOREACTION if no reaction occurs.

2Al + 3CuSO4 → Al2(SO4)3 + 3Cu What mass of copper can be produced when 20.69g of aluminum reacts with 88.88g of copper(II) sulfate? Round all answers to 2 decimal places Do NOT place a unit on the answer. If the answer is 3.44L type 3.44 in the box. If the answer is in scientific notation, this type of question on Canvas requires you to answer

2017年8月14日 · The only reason you are "just worried about the compounds with Al" is because it turns out that Al2(SO4)3 is the limiting reactant in this problem. Therefore the moles of this reactant will dictate the moles of all products formed.

2021年1月8日 · We need the molecular weights of both the Al 2 (SO 4) 3 and sulfur, S. Al 2 (SO 4) 3 = 342.2 amu. S = 32 amu. We have 3 sulfurs per molecule, so the total contribution of sulfur to the 342.2 is 3 x 32 = 96 amu. The percentage is thus (96amu)/(342.2 amu) = 0.28 or 28%. Bob
