2 molecules of Acetaldehyde is the product of a reaction of an alkene. One way in which alkenes can react to give carbonyl compounds (ketones/aldehydes) is the reaction with ozone, O₃. The ozonolysis of an alkene will result in cleavage of the carbon-carbon double bond and each carbon that was part of the alkene, will now have a double bond to oxygen. Each carbon of the original alkene will now be a carbonyl in the product.

To form 2 molecules of acetaldehyde, we must cleave an alkene that has the same substitution pattern on each side of the alkene so that the carbonyl compounds formed are identical. Therefore, both (E)- and (Z)-2-butene will react with ozone to give acetaldehyde. The scheme provided shows the reaction of both alkenes to give the acetaldehyde. The products are drawn in such a way to show which part of the original molecules they were derived from. However, both reactions do provide identical products.

sergij07 [2.7K]

Hydroponics is more than just another way to grow plants–the technology has the potential to change how we engage with food cultivation as a whole! For the first time since humans started tilling the land, modern hydroponics technology frees us from the soil beneath our feet, allowing us to bring food production indoors where we can layer in additional climate and lighting controls. The result is an ability to grow food anytime, anywhere in the world.

Express the quantity 556.2 x 10^-12 in each units A.) ms B.) ns C.) ps D.) fs

zavuch27 [327]

The answer:
we should know the meaning of each abbreviation:
ms means millisecond, its value is 10^-3 s
ns means means nanosecond, its value is 10^-9 s
ps means picosecond, its value is 10^-12 s
fs means femtosecond, its value is 1x 10^15 s

Expressions of the quantity 556.2 x 10^-12 are
556.2 x 10^-12 =556.2 ps
556.2 x 10^-12 =556.2 x 10^-9 x 10^-3= 556.2 x 10^-9 ms
556.2 x 10^-12 = 556.2 x 10^-3 x 10^-9 = 556.2 x 10^-3 ns
556.2 x 10^-12 = 556.2 x 10^- 27 x 10^15 = 556.2 x 10^- 27 fs

Answer:

The concentration of O2 will begin decreasing and The concentrations of CO2 and O2 will be equal.

Explanation:

Equilibrium occurs when the velocity of the formation of the products it's equal to the velocity of the formation of the reactants, thus the concentrations of the compounds remain constant.

Analyzing the information and the reaction given, we can notice that in equilibrium the rate (velocity) of formation of O2 (product) is equal to the rate of formation of CO2 (reactant).

As the CO2 and H2O are placed in the reaction, the Le Chateliêr's principle states that the equilibrium must shift to reestablish the equilibrium, thus, they must be consumed, and the concentration of O2 must increase.

As state above, in equilibrium, the concentrations didn't change, thus, the concentrations of CO2 and O2 will not change.

The concentrations of CO2 and O2 depends on the rate of the reaction and the initial quantities presented, so it's not possible to affirm they'll be equal.
