Answers

Answer 1
Answer:

Answer:

Second order

Δ[ClO⁻]/Δt = -  4.183 x 10⁻⁴ M/min

Explanation:

Given the data:

Experiment #         [ClO–] (M)   Initial Rate of Formation of ClO3– (M/min)

         1                      10.452                     1.048 x 10⁻⁴

         2                     20.903                    4.183 x 10⁻⁴

we need to determine the order of the reaction with respect to ClO⁻.

We know the rate law for this reaction will have the form:

Rate = k [ClO⁻]^n

where n is the order of the reaction. Thus, what we need to do is to study the dependence of the initial rate on n for the experiment.

If the reaction were zeroth order the rate would not change, so we can eliminate n= 0

If the reaction were first order, doubling the concentration of   [ClO–] , as it was done exactly in experiment # 2, the initial rate should have doubled, which is not the case.

If the reaction were second order n: 2, doubling the concentration of  [ClO–] , should quadruple the initial rate of formation of ClO3–, which is what it is observed experimentally. Therefore the reaction is second order respect to ClO–.

The initial rate of consumption of ClO⁻ is the same as the rate of formation of ClO₃⁻ since:

Δ = - Δ[ClO⁻]/Δt =  + Δ[ClO₃⁻]/Δt = + 1/2 [Cl⁻] /Δt

where t is the time.

from the coefficients of the balanced chemical equation.

- Δ[ClO⁻]/Δt =  + Δ[ClO₃⁻]/Δt  = + 1/2 [Cl⁻ ] = rate

Δ[ClO⁻]/Δt = -  4.183 x 10⁻⁴ M/min

Which element has chemical properties that are most similar to the chemical properties of sodium?(1) beryllium (3) lithium
(2) calcium (4) magnesium

Answers

Check out your periodic table. Elements in the same column (families) usually share similar properties because they have the same number of valence electrons. In this case, the only element listed that is part of Sodium's family is Lithium, so Lithium is most similar to Sodium.

Final answer:

Lithium is an element that has chemical properties most similar to sodium.

Explanation:

Out of the given options, lithium is the element that has chemical properties most similar to sodium.

Sodium and lithium are both in Group 1 of the periodic table, also known as the alkali metals. Alkali metals have similar properties because they all have one valence electron, which makes them highly reactive.

For example, like sodium, lithium reacts vigorously with water to produce hydrogen gas and a hydroxide:

2Li(s) + 2H2O(l) → 2LiOH(aq) + H2(g)

What is one benefit associated with a nuclear fission reaction?(1) The products are not radioactive.
(2) Stable isotopes are used as reactants.
(3) There is no chance of biological exposure.
(4) A large amount of energy is produced.

Answers

The correct answer is (4) A large amount of energy is produced in a nuclear fission reaction.
Choice (1) is false, the products are radioactive, and often have to be buried underground for long periods of time. Choice (2) is false, because the reactants are often unstable to allow them to decay and release energy. Choice (3) is false, because the radioactive substances can affect living organisms.
"A large amount of energy is produced" is by far the most associated with a nuclear fission reaction in terms of a benefit, in terms of making both power and bombs. 

The Resource Conservation and Recovery Act controls hazardous waste from its creation to its disposal. Please select the best answer from the choices provided. T F

Answers

Answer:

True

Explanation:

Resource Conservation and Recovery Act (RCRA). 1976 of United States Environmental Protection Agency(EPA) empowers EPA to control the production, transportation, storage, treatment and disposal of hazardous waste. The RCRA act was amended in 1984 and 1986 to include Waste minimization along with appropriate disposal (not in the landfill site) and tackling of petroleum hazardous waste respectively along with other waste.

Answer:

true is the correct answer.

Explanation:

  • The Resource Conservation and Recovery Act controls hazardous waste from its creation to its disposal is true.
  • The Resource Conservation and Recovery Act is the nation's premier law directing the control of solid and hazardous waste.
  • To control the increasing problems that the nation is facing from the municipal waste and the industrial waste Resource Conservation and Recovery Act was signed.
  • Resource Conservation and Recovery Act goals are to eliminate the quantity of waste produced and to protect  the human health and the atmosphere from the dangers posed with waste disposal

Certain substances such as H2O, HF, NH3 from hydrogen bonds, and the formation of which affects properties (mp,bp,solubility) of substance. Other compounds containing OH and NH2 groups also form hydrogen bond. Molecules of many organic compounds such as alcohols, acids, amines, and amino acids contain these groups, and thus hydrogen bonding plays an important role in biological science.

Neopentyl alcohol, (ch3)3cch2oh, cannot be dehydrated to an alkene without rearrangement. what is the chief product of dehydration?

Answers

Dehydration is removal of water.

In alcohols dehydration is α-β elimination or 1,2 elimination, it means the hydroxyl group will be removed from α-carbon while the hydrogen will be removed from near by carbon.

In case of neopentyl alcohol there is no β hydrogen present on the β carbon [as shown in figure].

The only possible way for it to undergo dehydration is by rearrangement.

The process or mechanism can be understood as:


so the chief product is 2-methylbut-2-ene
