Answer:
The concentration of reactants have no effect on the rate of reaction.
Explanation:
The strength of the nucleophile doesn't affect the reaction rate of an SN1 since the nuleophile is not involved in the rate determining step. Increasing the concentration of the substrate (which is a reactant) increases the rate of reaction even though increasing the concentration of the nucleopohile has no effect on the rate of reaction. The use of polar protic solvents assist an SN1 reaction hence the solvent used can affect the rate of reaction. However, temperature affects an SN1 reaction. Increasing the temperature will increase the rate of E1 elimination reaction rather than the SN1 reaction since the both are competing reactions. Lowering the temperature favours SN1 reaction. Hence the answer.
Answer:
11
Explanation:
Atomic number is the number of PROTONS an element has .
The answer is 4. It can hold 4 sublevels as s.p,d,f and it holds 32 electrons
Calculate first the number of moles of ethylene glycol by dividing the mass by the molar mass.
n = (6.21 g ethylene glycol) / 62.1 g/mol
n = 0.1 mol
Then, calculate the molality by dividing the number of moles by the mass of water (in kg).
m = 0.1 mol/ (0.025 kg) = 4m
Then, use the equation,
Tb,f = Tb,i + (kb)(m)
Substituting the known values,
Tb,f = 100°C + (0.512°C.kg/mol)(4 mol/kg)
<em>Tb,f = 102.048°C</em>
Answer:
Liquids and gases show random movements because of potential and kinetic energy.
It happens when heat is applied to the particles and they gain more potential and kinetic energy and move around faster. With gases, they have the most energy.
