Answer:
1.64g
Explanation:
The reaction scheme is given as;
2-bromocyclohexanol --> 1,2-epoxycyclohexane + HBr
From the reaction above,
1 mol of 2-bromocyclohexanol produces 1 mol of 1,2-epoxycyclohexane
3.0 grams of trans-2-bromocyclohexanol.
Molar mass = 179.05 g/mol
Number of moles = mass / molar mass = 3 / 179.05 = 0.016755 mol
This means 0.016755 mol of 1,2-epoxycyclohexane would be produced.
Molar mass = 98.143 g/mol
Theoretical yield = Number of moles * Molar mass
Theoretical yield = 0.016755 * 98.143 ≈ 1.64g
Answer:
This is true. A hot glass does look the same as a cold glass. Glass won't change its look if it's below 648 degrees Celsius.
Answer:
CO contains polar covalent bond, because these atoms share unequal electrons.
Answer:
it is an exothermic reaction
Explanation:
exothermic reactions have a negative ∆H
i.e, product of the reaction is less that the reactants of the reaction
(Note : ∆H= products - reactants), that's why it's exothermic
Answer:
more genetic variation within a population usually enables more phenotypic variation.
Explanation:
Because natural selection acts directly only on phenotypes, Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
