The energy diagrams of the synthesis, single replacement, and double replacement reactions are found in the attached image.

<h3>What are energy profile diagrams?</h3>

Energy profile diagrams are diagrams which illustrate the potential energy changes that occur when reactant molecule combine to form products.

The energy diagrams shows the potential energy of the reaction, the energy of the transition state of the reaction, the activation energy of the reaction, as well as the potential energy of the products.

From energy diagrams, the enthalpy change of a reaction can be determined. Also, it can also be established whether the reaction is exothermic or endothermic.

For exothermic reactions, the enthalpy change is negative since the potential energy of the reactants is greater than the potential energy of the products.

For endothermic reactions, the enthalpy change is positive since the potential energy of the reactants is less than the potential energy of the products.

Based on this therefore, the energy diagrams of the given reactions have been constructed and are found in the attached image.

In conclusion, energy diagrams are used to show energy changes occurring in a reaction.

The isotope Np-238 has a half life of 2.0 days if 96 grams of it were present on Monday how much will remain six days later
Kipish [7]

Answer:

12.02 g

Explanation:

From the question given above, the following data were obtained:

Half life (t½) = 2 days

Original amount (N₀) = 96 g

Time (t) = 6 days

Amount remaining (N) =..?

Next, we shall determine the rate of disintegration of the isotope. This can be obtained as follow:

Half life (t½) = 2 days

Decay constant (K) =?

K = 0.693 / t½

K = 0.693 / 2

K = 0.3465 /day

Therefore, the rate of disintegration of the isotope is 0.3465 /day.

Finally, we shall determine the amount of the isotope remaining after 6 days as follow:

Original amount (N₀) = 96 g

Time (t) = 6 days

Decay constant (K) = 0.3465 /day.

Amount remaining (N) =.?

Log (N₀/N) = kt / 2.303

Log (96/N) = (0.3465 × 6) / 2.303

Log (96/N) = 2.079/2.303

Log (96/N) = 0.9027

Take the anti log of 0.9027

96/N = anti log (0.9027)

96/N = 7.99

Cross multiply

96 = N × 7.99

Divide both side by 7.99

N = 96 /7.99

N = 12.02 g

Therefore, the amount of the isotope remaining after 6 days is 12.02 g

Which particle cannot be accelerated by the electric or magnetic fields in a particle accelerator?
77julia77 [94]

The neutrino is the particle that cannot be accelerated in a magnetic field.


To add, a neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero.

Many repeating, simple subunits are joined together. What is the most likely
Hatshy [7]

Answer:

O a polymer

Explanation:

When many repeating simple subunits are joined together, this results into a polymer.

The simplest unit or smallest unit of any substance is called a monomer. When many units of a monomer joins together, a polymer results.

  • For proteins, the monomeric unit is amino-acid.
  • When they combine they form longer chain molecules called proteins.
  • For carbohydrates, the monomeric unit is called glucose.
  • When they are combined they give us a wide range of carbohydrate molecules.

Group 17 is called the halogen family, and the group to its right is called the noble gases. How are these elements alike and ho
Vesnalui [34]

Explanation:

The halogen family and noble gases are similar in just one particular way, they are groups of non-metals. All members of these two groups are categorized as non-metals.

Here are some of the differences between them;

  • Halogens have 7 electrons in their outermost shell whereas noble gases have 8 electrons in theirs.
  • Halogens are highly reactive elements, noble gases are non-reactive.
  • Halogens are made up of electronegative elements where as noble gases are neither electropositive nor electronegative.
