Co2+ + 2SO4
While many compounds containing sulfate are soluble, barium sulfate is one of the exceptions. When you put it in water, nothing happens.
Nothing will happen. Displacement reaction only happens when the element is more reactive than the salt solution. An example will be the otherwise. If you put aluminum metal into a solution of Copper (II) Sulfate. The aluminum metal will displace copper metal and you will have a solution of Aluminum Sulfate and copper metal. As long the element you put into the salt solution is more reactive than the cation of the solution, it will displace the metal.
Yes. Iron is more reactive than copper, so will displace it from a compound. If you put a piece of iron into copper sulfate solution, it will be soon coated with a deposit of orangey red copper.CuSO4 + Fe --> FeSO4 + Cu
Copper sulphate is soluble, sulphur is insoluble. Dissolve the mixture in water. The copper sulphate will dissolve, the sulphur will not dissolve. Filter. The blue soluble of copper sulphate will passthrough the filter paper. The sulphur (yellow) will remain in the filter paper.
The evidence to see are 1. has no colour or smell 2. will put out a lit splint
Write the reaction when potassium sulfide is put into water:
This compound is soluble in water.
Any reaction occur when gold is put in copper sulfate.
CoF_2 (s) --> Co^2+ (aq) 2F^- (aq)
While many compounds containing sulfate are soluble, barium sulfate is one of the exceptions. When you put it in water, nothing happens.
Since selenium is a metalloid, and nitrogen is a nonmetal, the normal convention would require us to put nitrogen at the end, not the beginning. Se4N4 is a highly explosive compound called selenium nitride. Other forms of selenium nitride also exist, with different ratios of selenium to nitrogen.
It is soluble in water so a green solution is formed.
you can put cheese in it and then drink it
You cannot balance these two compounds (barium chloride and sodium sulfate, respectively) because they are not in a chemical reaction. However, if you put them in an equation (also known as a reaction), it can be balanced as follows: BaCl2 => Ba++ + 2Cl2+ Na2SO4 => 2Na+ + SO4-- (SO4 is a polyatomic ion known as sulfate) Both equations represent what will happen to either of these chemical compounds when they dissolve in water. Both of these ionic compounds are water soluble, and will "break up" into ions in water.
Yes, it is true.
Any reaction occur; sucrose is dissolved in water.
This is not a chemical reaction; it is only a dissolution.
