Kevin draws a lewis structure for the molecule of ozone, o3. later on that day, he draws another one for a friend to show what h

Paha777 [63]

The most important part of a lewis structure is that it's number of valence electrons matches the number needed for the atom(s). Because lewis structures are drawn with many "slots" for valence electrons, they can be assigned in a loose order as long as they do not inherently change the shape or number of electrons for the atom. Therefore different lewis structures can be formed, just keep the variables the same.

What is the definition of an Arrhenius acid?

Lorico [155]

Answer:

I think your answer is: C. ("An Arrhenius acid increases [H +] in the solution.")

Explanation:

An Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H + ); that is, an acid increases the concentration of H + ions in an aqueous solution. This causes the protonation of water, or the creation of the hydronium (H 3 O +) ion.

Hopefully this helps!

Have a great day! ^^

Given the equation representing a reaction:H2(g) + I2(g) → 2HI(g)Which statement describes the energy changesthat occur in this

Korvikt [17]

The given question is incorrect, here is a complete question.

Given the equation representing a reaction:

$H_2(g)+I_2(g)\rightarrow 2HI(g)+Energy$

Which statement describes the energy changes that occur in this reaction?

(1) Energy is absorbed as bonds are formed, only.

(2) Energy is released as bonds are broken, only.

(3) Energy is absorbed as bonds are broken, and energy is released as bonds are formed.

(4) Energy is absorbed as bonds are formed, and energy is released as bonds are broken.

Answer : The correct option is, (3) Energy is absorbed as bonds are broken, and energy is released as bonds are formed.

Explanation :

Bond energy : It is defined as the amount of energy required to break a molecules into its component atoms.

At the time of bond formation, the energy is released and at the time of bond breaking, the energy is absorbed.

In the chemical reaction, when the energy is shown in product side that means the energy is released.

In the chemical reaction, when the energy is shown in reactant side that means the energy is absorbed.

Hence, the correct option is, (3)

Which of the following solutions is more concentrated? 0.50M KCl or 5.0% (w/v) KCl

HACTEHA [7]

.50 M KCl because 5% is the same as .05, which makes the .50M more concentrated.
