Answer:
Crossing over Mitosis
Explanation:
A process called meiosis ensures siblings share just about 50% of their genotype. That's how siblings can have different DNA. Meiosis is a form of cell division that is only used to produce a special category of cells, called gametes.
Answer:
Option C. PV = nRT
Explanation:
The ideal gas gas equation gives the relationship between pressure, volume, number mole a gas and temperature of gas.
Mathematically, the ideal gas equation is given as:
PV = nRT
Where:
P is the pressure measured in atmosphere (atm).
V is the volume measured in litres(L) or cubic decimetre (dm³).
n is the number of mole of gas.
R is the gas constant (0.0821atm.L/Kmol)
T is temperature measured in Kelvin (K).
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
