The correct answer is potential energy.

Potential energy is when an object can store energy as the result of its position.

Gravitational potential energy is the energy stored between an object and the Earth.

Elastic potential energy is the energy stored in objects that are compressed or stretched.

Chemical potential energy is the energy stored in the bonds between atoms.

Which of the following is not a reason for creating hybrid plants?

Softa [21]

I say C because why would you want a plant to resist something that helps it grow? A, B, and D make sense because those can improve the quality of the plant, but fertilizer can improve plant quality and help it grow. So there is no reason to resist it.

Answer:

see below

Explanation:

Aqueous hydroiodic acid reacts with liquid water in a reversible reaction.

2 HI + 2 H₂O ⇔ 2 H₃O + I₂

This is an acid-base reaction. HI is the acid, and H₂O is the base. The conjugate acid is H₃O, and the conjugate base is I₂. You can figure out the acid and base by a using a table of strong/weak acids and bases. The conjugate will have one less or one more H⁺ depending on if it's an acid or a base.

The expression for Kₐ of the reaction is below. You have to put the acid and its conjugate base on the top and the base and its conjugate on the bottom. I didn't put in H₂O since, although it is the base in this equation, it isn't really a base.

$K_{a}=\frac{[HI][H_{3}O] }{[I_{2}] }$

Solid zinc reacts with solid manganese (IV) oxide producing solid zinc oxide and solid manganese (III) oxide.

Zn + 2 MnO₂ ⇒ ZnO + Mn₂O₃

This is a redox reaction. The Zn is being oxidized, and the Mn is being reduced.

Oxidation: Zn ⇒ Zn⁺² + 2 e⁻

Reduction: Mn⁺⁴ + e⁻ ⇒ Mn⁺³

Aqueous silver nitrate reacts with aqueous calcium chloride.

2 AgNO₃ + CaCl₂ ⇒ 2 AgCl + Ca(NO₃)₂

This is a precipitation reaction. You have two soluble salts combing to form a solution. You now need to figure out which of the compounds produced are not soluble. AgCl is the compound that is not soluble in water, making it the precipitate.

I think I covered everything. If I missed something let me know.

Based on the octet rule, nitrogen most likely forms a __ion.

Greeley [361]

Answer:

b) N3-

Explanation:

The octet rule stipulates that a chemical specie is stable if it has eight electrons in its outermost shell.

Nitrogen belongs to group 15. This means that it has five electrons in its outermost shell. The formation N3- means that it accepted three electrons.

This brings the total number of outermost electrons to eight in accordance with the octet rule.

A balloon filled with air has a volume of 4.24 liters at 23.00°C. If the balloon is cooled at constant pressure to 5.00°C, what

Ierofanga [76]

Answer:

The new volume will be

0.7 L

Explanation:

This is an example of Charles' law, sometimes called the temperature-volume law. It states that the volume of a gas is directly proportional to the Kelvin temperature, while pressure and amount are held constant.
