Answer:

Compounds with Carbonate ions are less soluble than the compounds with Chlorate ions.

Explanation:

The reason is that the compounds with carbonate ions have less attraction between positive and negative charges. (Solvation)

Explain why the following chemical equation represents a Lewis acid-base reaction. H+ + NH3 —>NH4+

lozanna [386]

Answer:

Due to an electron-pair acceptor and donor.

Explanations:

Lewis acid can be defined as an electron-pair acceptor. An example is Hydrogen ion(H+). This is because it is a proton and it distributes positive charge which means that it accepts electrons(negative charge).

Lewis base can be defined as an electron-pair donor. This is because it donates electrons to be accepted by the proton. An example is ammonia(NH3).

The decomposition of hydrogen peroxide follows first order kinetics and has a rate constant of 2.54 x 10-4 s-1 at a certain temp

Eva8 [605]

Answer:

$[A]_0=0.400M$

Explanation:

Hello.

In this case, since the first-order reaction is said to be linearly related to the rate of reaction:

$r=-k[A]$

Whereas [A] is the concentration of hydrogen peroxide, when writing it as a differential equation we have:

$\frac{d[A]}{dt} =-k[A]$

Which integrated is:

$ln(\frac{[A]}{[A]_0} )=-kt$

And we can calculate the initial concentration of the hydrogen peroxide as follows:

$[A]_0=\frac{[A]}{exp(-kt)}$

Thus, for the given data, we obtain:

$[A]_0=\frac{0.321M}{exp(-2.54x10^{-4}s^{-1}*855s)}$

$[A]_0=0.400M$

Best regards!

Given the model from the question,

The products are: N₂, H₂O and H₂
The reactants are: H₂ and NO
The limiting reactant is H₂
The balanced equation is: 3H₂ + 2NO —> N₂ + 2H₂O + H₂

<h3>Balanced equation </h3>

From the model given, we obtained the ffolowing

Red => Oxygen
Blue => Nitrogen
White => Hydrogen

Thus, we can write the balanced equation as follow:

3H₂ + 2NO —> N₂ + 2H₂O + H₂

From the balanced equation above,

Reactants: H₂ and NO
Product: N₂, H₂O and H₂

<h3>How to determine the limiting reactant</h3>

3H₂ + 2NO —> N₂ + 2H₂O + H₂

From the balanced equation above,

3 moles of H₂ reacted with 2 moles of NO.

Therefore,

5 moles of H₂ will react with = (5 × 2) / 3 = 3.33 moles of NO

From the calculation made above, we can see that only 3.33 moles of NO out of 4 moles given are required to react completely with 5 moles of H₂.

Thus, H₂ is the limiting reactant

Identify the molecular shape of each Lewis structure.

saw5 [17]

Panel One

Trigonal Planar: This is in the shape of a triangle. It is an equilateral triangle with three equal atoms/ions at each corner of the triangle. The most well known example is a molecule with Boron at the center and the corner molecules some like Florine or iodine.

Trigonal Planar is the second Lewis Diagram from the right.

The uploaded picture is the second from the left.

==========

Tetrahedral (Second Lewis Diagram from the left) is something like a pyramid except that that the base is triangular as are each of the faces. The carbon is in the center and the chlorines (in this example) are each in a corner. If this made of just carbon (like diamond or anthracite coal) then you are talking about something that is extremely hard. It's the first upload on the left.

=====================

The Trigonal pyramid is the first Lewis Diagram on the left. It usually has an unattached pair of electrons. Nitrogen or Phosphorous are ususally the samples in the center. The nitrogen with its unused paired electrons are at the peak of blue sphere in the diagram that is uploaded second from the right.

======================

The Bent one is first lewis diagram on the right. It bends because of the unbalance (and double bonds) away from the nitrogen. Water looks something like that. Water is an example of Bent.

The upload is first on the right. These diagrams help you visulize what the various molecules look like

Problem Two

The very quick answer is E. Water is a bent molecule. It is flat. It has a very definite (+) end and a very definite (-) end. The marriage of a plus end with a minus is a very long lasting relationship. It is not the strongest bond in the world, but it is strong enough to create all the properties that the stem of the question has listed. [High melting and boiling points and high surface tension.

A is a repulsive condition. Likes repulse. Wrong answer.

B is wrong. We are talking about water itself, not water with something in it.

C is Wrong. Water molecules are distinct. They are a bit on the hermit side. They do not connect directly with each other.

D Wrong. There is no interchange of electrons between molecules.
