How many grams of aluminum chloride can be made from 67.0 grams of aluminium and excess hydrochloric acid?
The answer is: approx. 327 g.
Name a salt which gives white precipitate on ammonium hydroxide solution and is insoluble in excess?
One such salt would be aluminum chloride since it is soluble but when reacted with ammonium hydroxide, the insoluble aluminum hydroxide forms a precipitate. Not sure what is meant by "is insoluble in excess", however.
Why excess barium chloride is added to the filtrate in the preparation of a dry sample of barium sulphate?
Barium chloride in excess is added to be sure that the reaction is complete.
If you put excess iron III chloride in zinc what could be the products?
Go to your school lab and do it to find out. Let me know your results.
What happens to Calcium chloride in air?
When exposed to air, calcium chloride can absorb moisture and become hydrated, forming a white, powdery substance. It is hygroscopic, meaning it has a strong affinity for water molecules in the air. This property allows calcium chloride to be used as a desiccant to remove excess moisture from the air.
When 4 moles of aluminum are allowed to react with an excess of chlorine gas Cl2 how many moles of aluminum chloride are produced?
4 moles
You are given 34.0 g of aluminum and 39.0 g of chlorine gas. If you had excess chlorine how many moles of aluminum chloride could be produced from 34.0 g of aluminum?
1.26 mol of AlCl3
How many grams of aluminum chloride can be made from 67.0 grams of aluminium and excess hydrochloric acid?
The answer is: approx. 327 g.
How many grams of aluminum chloride are produced when 18 grams of aluminum are reacted with an excess of hydrochloride acid?
The empirical formula for aluminum chloride is AlCl3, and its gram formula mass is 133.34. The formula shows that each formula unit contains one aluminum atom, and the the gram atomic mass of aluminum is 26.9815. Therefore, 18(133.34/26.9815) or 89 grams, to the justified number of significant digits, of aluminum chloride will be produced.

When 4 moles of aluminum are allowed to react with an excess of chlorine gas how many moles of aluminum chloride are produced?
Four:2 Al + 3 Cl2 --> 2 AlCl3so: 4 Al + 6 Cl2 --> 4 AlCl3
What happens when chloride is taken in excess?
vomitting
Why excess barium chloride is added to the filtrate in the preparation of a dry sample of barium sulphate?
Barium chloride in excess is added to be sure that the reaction is complete.
What happens when excess chloride is consumed?
weakness and vomitting
What is the concentration of chloride ion in 229 mL solution if the addition of excess silver nitrate precipitates 8.07 g silver chloride?
If the addition of excess silver nitrate precipitates 8.07 g silver chloride, the concentration of chloride ion in 229 mL solution is .25.
What is the colour given by excess lithium in lithium chloride?
yellow
When 0.440 mol of aluminum are allowed to react with an excess of chlorine gas Cl2 how many moles of aluminum chloride are produced?
Equation. 2Al + 3Cl2 -> 2AlCl3 one to one again 0.440 moles Al (2 moles AlCl3/2 moles Al) = 0.440 moles AlCl3 produced
