Answer:
Arranged in order of most soluble to least soluble in water:
Explanation:
Water is a polar solvent due to the electric charge it possesses. Hence it would only dissolve polar molecules.
Non-polar molecules would be dissolved by non-polar solvents.
Short chain alcohols are more soluble than butanol, but generally the polar -OH group is soluble in water.
The question is incomplete, here is the complete question:
Write a balanced chemical equation for each single replacement reaction that takes place in aqueous solution. write no reaction if a reaction does not occur
1.) Zn + PbCl₂
2.) Cu + Fe(NO₃)₂
<u>Answer:</u>
<u>For 1:</u> The reaction does occur.
<u>For 2:</u> The reaction does not occur.
<u>Explanation:</u>
Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element.
The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series.
For the given options:
Zinc is more reactive than lead as it lies above in the series. So, it will displace lead from its chemical equation.
The chemical equation for the reaction of zinc and lead chloride follows:
Copper is less reactive than iron as it lies below in the series. So, it will not displace iron from its chemical equation.
The chemical equation for the reaction of copper and iron (II) nitrate follows:
I believe that crude oil is derived from plants because it is made up of a liquid that is found beneath the earth surface so I guess you could go with plants it is not an animal or rock or salt so.. could be brainliest not 100% sure so if you are not sure go with your gut
I would suggest convection !!!
The combstion of ZnS in excess oxygen gives ZnO and SO₂ as the products.
hence the equation should be;
ZnS(s) + O₂(g) →ZnO(s) + SO₂(g)
At the left hand side: At the right hand side:
number of Zn atoms = 1 number of Zn atoms = 1
number of S atoms = 1 number of S atoms = 1
number of O atoms = 2 number of O atoms = 3
Hence the balanced equation is;
2ZnS(s) + 3O₂(g) →2ZnO(s) + 2SO₂(g)
