What is the theoretical yield if 50grams of copper are allowed to react with excess chlorine 101.6grams of copper chlorine are formed?
The product in that reaction is Copper Chloride; Copper has two ionic states, +2 and +3, so the possible products are Copper(II)Chloride and Copper(III)Chloride. The result would be different numbers of moles of product and different weights per mole
Theoretical yield is how much product you would get if all of the limiting reagent (in this case Copper) reacted. Actual yield is in percent is (amount you actually got/theoretical yield)X100. Also, you have to convert grams to moles for each part of the reaction, since stoichiometric relationships are expressed as mole ratios.
The first thing you have to do is write a balanced chemical equation for the reaction:
Cu + Cl2 = CuCl2 OR 2Cu + 3Cl2 = 2CuCl3
Then you have to convert Reactants and Products from grams to moles:
Moles=Weight you have/Molecular weight (or Atomic weight for elements)per Mole (The math is left as an exercise for the student)
Next, use the Molar Ratios from the appropriate Balanced Equation to calculate how much you'd get for 100% yield and how much you actually got (also left for the student) in Moles .
Lastly, plug the answers you calculated into the Yield equation.
TA DAA, all the yield answers you want.
P.S. It's not my policy to do all the work. You are the Student, and you won't learn anything if I do your homework for you. Most often, the actual answer is of minor importance, what's most important is the concept and set-up; you're learning how to think and solve problems.

Is chlorine bad for dogs?
Not really, but just check your dogs' skin to make sure nothing is wrong, like a rash or anything. If there is then take them to the vet to see what to do about it. But chlorine isn't bad for dogs, actually it's very good for dogs to swim around. =)
When chlorine gas is added to water what compounds are formed?
Chlorine dissolves in water. The solution is known as chlorinated water and freshly prepared solution of chlorine water contains HCL and HOCL. Chlorine is a strong oxidising agent because hypochlorous acid is unstable and decomposes into HCL and nascent oxygen.
When 4 moles of aluminum are allowed to react with an excess of chlorine gas Cl2 how many moles of aluminum chloride are produced?
When 4 moles of aluminum react with an excess of chlorine gas, 4 moles of aluminum chloride are produced. This is because the balanced chemical equation for the reaction is: 2Al + 3Cl2 -> 2AlCl3 This means that 2 moles of aluminum react with 3 moles of chlorine gas to produce 2 moles of aluminum chloride, so 4 moles of aluminum will produce 4 moles of aluminum chloride.
What are chlorine and mustard gases?
Chlorine and Mustard gas are gaseous chemical compounds that are highly toxic to humans. They were both used as weapons during the First World War and both compounds were favored by the Central powers. Chlorine gas was the first chemical weapon used in the war at the second battle of Ypres. It was released from large tanks and allowed to drift towards Allied positions. Chlorine is heavier than air and thus stays close to ground level, making it very effective in trench warfare. Mustard gas was not commonly used in such a massive release and was most often deployed via artillery bombardment. Mustard gas blisters the lungs and other exposed areas and is generally more lethal than chlorine. Like all chemical weapons, mustard and chlorine gas are considered prohibited weapons under the Geneva conventions.
When 4 moles of aluminum are allowed to react with an excess of chlorine gas how many moles of aluminum chloride are produced?
When 4 moles of aluminum reacts with an excess of chlorine gas, it forms 4 moles of aluminum chloride. This is because the balanced chemical equation for the reaction is Al + 3Cl2 -> 2AlCl3, indicating a 1:1 molar ratio between aluminum and aluminum chloride.
What is chlorine not allowed to be mixed with?
Topeka
Under sara title 3 how many pounds of chlorine is allowed without a permit?
The reportable quantity of chlorine is 10 lbs.
Why is the actual discharge through an orifice less than theoretical discharge?
Because the baby goats aren't allowed to swim in the ocean. =(
How many additional minutes after the desired chlorine residual is obtained in a 36 gallon Lyster bag is the water allowed to stand before use?
Typically, the water in a Lyster bag is allowed to stand for an additional 30 minutes after the desired chlorine residual is obtained before it is considered safe for consumption.
Will the chlorine tablet you dropped into the pool not the filter canister put a hole in your liner?
Chemicals, especially chlorine, should not be allowed to sit on a pool's liner for any period of time. This will cause bleaching and could damage your liner.
Does a bettas water need to be dechorlified?
Chlorine will kill just about anything so yes it has to be removed. Because chlorine is a gas it will evaporate off from tap water given time, so provided the water is allowed to stand overnight there is no need to use chemicals to remove it.
Can you give an American toad tap water to soak in?
Yes. You can. But I would advise to let it sit in an open pot and air for at least 24 hours to let the chlorine content it contains be allowed to evaporate. The same goes for fish tanks. High levels of chlorine can be harmful and even deadly to reptiles and fish who are not accustomed to chlorine in their environment. Use rain water if you can.
Why was being an theoretical physicist so important to albert einsteien?
Being a theoretical physicist was important to Albert Einstein because it allowed him to explore complex scientific theories, such as the theory of relativity, that revolutionized our understanding of space, time, and gravity. Einstein's work paved the way for countless advancements in physics and has had a profound impact on our modern world.

What scientific skill was used when scientist grouped chlorine the other natural elements?
Classification was used to group chlorine with other natural elements based on similarities in properties such as reactivity, atomic structure, and chemical behavior. This process allowed scientists to organize elements into the periodic table and understand their relationships and patterns.
How did gay-lussac's experiment allow the chemical formula of hydrogen gas and chlorine gas to be dedeced?
Gay-Lussac's experiment involved the combination of hydrogen and chlorine gases to form hydrogen chloride gas. By measuring the volume of the gases before and after the reaction, he observed that the volumes of the reactants and products were in simple whole number ratios, providing evidence for the law of combining volumes. This allowed him to deduce the chemical formula of hydrogen gas (H2) and chlorine gas (Cl2).
When chlorine gas is added to water what compounds are formed?
Chlorine dissolves in water. The solution is known as chlorinated water and freshly prepared solution of chlorine water contains HCL and HOCL. Chlorine is a strong oxidising agent because hypochlorous acid is unstable and decomposes into HCL and nascent oxygen.
