When is buying a house better than renting

1 answer:

5 0

The answer for that kind of question depends on many things. location, how many people will inhabit the home, whether or not the home is a vacation home or a full time home. etc. P.S. I do not believe that this has anything to do with chemistry

How will the reaction rate of the SN1 reaction change if the electrophile is switched from the tertiary electrophile to a second

lions [1.4K]

The reaction rate of the SN1 reaction change if the electrophile is switched from the tertiary electrophile to a secondary electrophile will decrease.

SN1 exhibits substitution, nucleophilicity, and monomolecular reaction, and is expressed by the expression rate = k [R-LG]. This means that the rate-determining step of the mechanism depends on the degradation of a single molecular species. Multi-step reactions include intermediates and multiple transition states (TS).

The SN1 reaction is a nucleophilic substitution reaction in which the nucleophile replaces the leaving group (similar to SN2). However, the SN1 reaction is a single molecule. The rate of this reaction depends on the concentration of only one reactant.

The rate of diffusion of gas A is double the rate of gas B. The ratio of their molecular weight is

Dafna1 [17]

Answer:

Ratio is 4:1

Explanation:

from graham's law of gaseous diffusion:

${ \bf{ \frac{R _{A} }{R_{B} } = \sqrt{ \frac{M_{A} }{M_{B}} } }}$

but Ra = 2Rb:

${ \sf{ (\frac{2}{1} ) {}^{2} = \frac{M _{A}}{M _{B} } }} \\ \\ { \sf{\frac{M _{A}}{M _{B} } = \frac{4}{1} }} \\ \\ {M _{A}} : {M _{B} } = 4 :1$

Calculate the activation energy (ea in kj/mol for a reaction if the rate constant (k is 2.7 × 10-4 (m−1sec−1 at 600 k and 3.5 ×

djyliett [7]

Below are the choices:

a. −166 kJ/mol
b. 166 kJ/mol 
c. 1.64 kJ/mol 
d. 1.66 × 10^5 kJ/mol

To calculate the activation energy of a reaction, we use the Arrhenius equation. You may want to look it up to see how and why it works. In the problem you posted, there are two temperatures and two rate constants. After some rearranging and substitution of the Arrhenius equation, we have Ea = R T1 T2/(T1-T2) ln(k1/k2) = 8.314 J/mol K (600 K)(650 K)/(600 K-650 K) ln(2.7×10^-4 M^−1sec^−1/3.5×10^−3 M−^1sec^−1) = 166145 J/mol = 166 kJ/mol => choice b

Avogadros number is used to determine the number of subatomic particles in an atom. True or false

Yuliya22 [10]

Answer:

False

Explanation:

The Avogadro's number is not used to determine the number of subatomic particles in an atom.

Subatomic particles of an atom are the protons, neutrons and electrons.

The protons are the positively charged particles in an atom

Neutrons do not carry any charges

Electrons carry negative charges.

The number of protons, neutrons and electrons in an atom are experimentally determine using spectrometric techniques.

Calculate the density of SO3 gas at STP. Show all work.

Kipish [7]

When the density formula at STP is:
density = molar mass / molar volume

So we can get the molar mass of SO3 from the periodic table = 32 + (16x3) = 80g

and at STP each 1 mole of gas occupy 22.4 L so we have the molar volume at STP = 22.4.
So by substitution in the density formula:
∴ density of SO3 = 80 g / 22.4 L = 3.571 g /L
