B.) 0.14 m/a, northeast is your answer.

Answer:

0.14 m/s, northeast

Explanation:

It is given that,

Distance travelled in east direction, x_1=3\ m

Distance travelled in north direction, x_2=4\ m

The shortest path or the displacement of Jesse is, x=\sqrt{x_1^2+x_2^2}

x=\sqrt{3_1^2+4_2^2}

x = 5 m   ( in northeast direction )

Time taken, t = 35 seconds

Jesse's velocity is defined as the net displacement divided by total time taken i.e.

v=\dfrac{x}{t}

v=\dfrac{5\ m}{35\ s}

v = 0.14 m/s

So, the velocity of Jesse is 0.14 m/s and it is in northeast direction. So, the correct option is (b) "0.14 m/s, northeast".

Predict the shape and hybridization of platinum tetrachloride (PfCl4)​
guapka [62]

Answer:

Shape- square planar , hybridisation-sp3

Explanation:

Shape:

  1. VSPER theorey is used to determine both electron geometry and molecular geometry of a molecule.(PtCl4)2 molecular geometry is square planar
  2. Hybridisation:It undergoes sp3 hybridisation.since there are 2 unpaired electrons in this case, it is paramagnetic in nature

The reaction of 2-chloropropane with sodium hydroxide can occur via both SN1 and SN2 mechanisms.
strojnjashka [21]

Answer:

Explanation:

(a) Part 1: S_N1 reaction. This is a nucleophilic substitution reaction in which we have two steps. Firstly, chlorine, a good leaving group, leaves the carbon skeleton to form a relatively stable secondary carbocation. This carbocation is then attacked by the hydroxide anion, our nucleophile, to form the final product.

To summarize, this mechanism takes places in two separate steps. The mechanism is attached below.

Part 2: S_N2 reaction. This is a nucleophilic substitution reaction in which we have one step. Our nucleophile, hydroxide, attacks the carbon and then chlorine leaves simultaneously without an intermediate carbocation being formed.

The mechanism is attached as well.

(b) The rate determining step is the slow step. Formation of the carbocation has the greatest activation energy, so this is our rate determining step for S_N1. For S_N2, we only have one step, so the rate determining step is the attack of the nucleophile and the loss of the leaving group.

If it requires 75.0mL of 0.500M NaOH to neutralize 165.0 mL of an hcl solution what is the concentration of the hcl solution
Kaylis [27]

Answer:

0.027 M HCl

Explanation:

The chemical equation of the neutralization is:

1 NaOH + 1 HCl -> 1 H2O + 1 NaCl

Because the ratio of NaOH and HCl is 1:1 you can use the M1V1=M2V2 formula.

(75 mL)(0.5 M NaOH) = (165 mL)(M HCl)

It requires 0.027 M HCl.

Select the correct Answers.
Mandarinka [93]

Answer:

3. The temperatures of the two substances equalize.

Explanation:

  • As two objects at different temperatures are placed in contact, heat is transferred from the warmer to the cooler object until the temperature of the two objects be the same.
  • The amount of heat that is transferred from the warmer object is equal to the amount of heat that is transferred into the cooler object.
  • This is in agreement with the law of conservation of energy.
  • <em>So, the right choice is: 3. The temperatures of the two substances equalize. </em>
