The first one is right and so is eight you have to add them together to see if they go together if they dont add what is missing
Answer:
55 g
Explanation:
First, we have to look for the solubility of KNO₃ at 60°C, considering that the solubility is the maximum amount of solute that can be dissolved in 100 grams of solvent, that is, the concentration of a saturated solution.
The solubility of KNO₃ at 60°C is 110.0 g of KNO₃ per 100 g of water. The mass of KNO₃ that must be dissolved in 50 g of water to make a saturated solution is:
50 g H₂O × (110.0 g KNO₃/100 g H₂O) = 55 g KNO₃
Answer:Methane gas is evolved from the reaction mixture.
Explanation:
When ethyl acetoacetate is treated with grignard reagent a carbanion is generated.
There are two acidic hydrogens which are present on the carbon which is in between the ester and the ketone group in ethylacetoacetate.
These two protons are also called active methylene protons and they are very acidic in nature due to the presence of two electron withdrawing substituents that is an ester and ketone.
CH₃MgBr is grignard reagent and it is an organo-metallic copmpound . Carbon here in CH₃MgBr exists as carbanion CH3⁻ which is basic enough to abstract the acidic protons present on ethylacetoacetate.
As CH3⁻ abstracts an acidic proton from ethylacetoacetate it become CH₄ which is methane. As methane is a gas so it is methane gas which is evolved from the reaction mixture.
As the acidic proton is abstracted from ethylacetoacetate which leads to generation of carbanion and this carbanion is very stable as it can be delocalized on to the two carbonyl groups . As we add aqueous acid to the reaction mixture the carbanion can again be protonated and its protonation would lead to the generation of ethylacetoacetate again.
A<span>toms are always bonded so that nearby atoms have to form into a compound and can be classified into different forms of compounds or molecules. It is also integral in our everyday life.</span>
