Answer:
4-chloro-4-methyl-cyclohexene.
Explanation:
Hello,
On the attached picture you will find the chemical reaction forming the required product, 4-chloro-4-methyl-cyclohexene. In this case, according to the Markovnicov’s rule, it is more likely for the chlorine to be substituted at the carbon containing the methyl radical in addition to the hydrogen to the next carbon to break the double bond and yield the presented product.
Best regards.
<span>1 drop is approximately 0.05mL. Since 0.500L of 0.550M NH4Cl contains 0.275mol of substance (calculated by using c=n/V formula), equal amount of substance of NH3 is needed to neutralize this solution (since pH of 7 is neutral solution). Thus, we need 0.0275L of NH3, i.e. around 550 drops.</span>
Answer:
2.8M
Explanation:
The following data were obtained from the question:
Volume of stock solution (V1) = 40mL
Molarity of the stock solution (M1) = 7M
Volume of diluted solution (V2) = 100mL
Molarity of diluted solution (M2) =?
Using the dilution formula, we can easily find the molarity of the diluted solution as follow:
M1V1 = M2V2
7 x 40 = M2 x 100
Divide both side by 100
M2 = (7 x 40)/100
M2 = 2.8M
Therefore, the molarity of the diluted solution is 2.8M
Answer:
yes it is true
Explanation:
evaporation occurs when burning liquid water changes into gas.
Answer: Option (B) is the correct answer.
Explanation:
According to Le Chatelier principle, when a system is in equilibrium then any change in the reaction will shift the equilibrium in a direction which is opposing the change.
For example, when heat is added to a system the molecules will gain kinetic energy. So, rate of reaction will increase hence, product formation will increase but equilibrium will shift in the opposite direction.
Hence, we can conclude that according to Le Chatelier's principle, the reaction shifts to remove the heat if heat is added to a system.
