Answer:
The products formed are
2-methyl-3-isopropylnonan-3-ol and 2-methyloctan-2-ol
The products should be in equal ratio since an equipmolar amount of acetone and 2,4-dimethylpentan-3-one was initially present as reactants
Explanation:
Ketones reacts with gridnard reagents to form tertiary alcohol, and since acetone and 2,4-dimethylpentan-3-one are both ketones, gridnard reagent reduced both to tertiary alcohols:2-methyl-3-isopropylnonan-3-ol and 2-methyloctan-2-ol
The answer is 53.8 kJ.
Solution:There are two major steps in converting ice to liquid water. It begins with a phase change when ice melts at 0.0°C, and then a temperature change when the liquid water rises in temperature from zero to 32°C.
The amount of heat involved with the phase change melting is given by
q = (mass of water) (ΔHfus)
= (115.0 g)(334 J/g)
= 38410 J = 38.41 kJ
The amount of heat involved with temperature change is
q = mcΔT
= (115.0g)(4.184J/g°C)(32°C - 0.0°C)
= 15397.12 J = 15.39712 kJ
Summing up the two values gives the total heat required to convert ice to liquid water:
q = 38.41 kJ + 15.39712 kJ= 53.8 kJ
Answer:
Two
Explanation:
In a double-replacement reaction, there will be two reactants and two products.
It is called double replacement reaction because one element in reactant 1 replaces an element in reactant 2 and other element in reactant 2 replaces other element in reactant 1.
Here two replacements are taking place. Hence, this is called double replacement reaction.
A Neutralization reaction i.e an Acid - Base reaction is a good example of Double replacement reaction.
An Example is provided below for better understanding :
HNO3 + NaOH --> NaNO₃ + H₂O.
Here HNO₃ is the acid and NaOH is the base which are the reactants.
NaNO₃ and H₂O are the products.
This is a double replacement reaction because,
Hydrogen(H) in HNO₃ replaces Sodium(Na) in NaOH, and
NO₃ in HNO₃ replaces OH in NaOH.
Here, there are 2 reactants and 2 products.
Answer:
P2 = 2.25 atm
Explanation:
Given:
V1 = 1.5 L. V2 = 2.0 L
P1 = 3.0 atm. P2 = ?
Use Boyle's law and solve for P2:
P1V1 = P2V2
or
P2 = (V1/V2)P1
= (1.5 L/2.0L)(3.0 atm)
= 2.25 atm
