The phrase which best describes nuclear fusion is: A. the process by which small nuclei combine into a larger nucleus.
A nuclear reaction can be defined as a type of chemical reaction in which the nucleus of an atom of a radioactive chemical element is transformed by either being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive chemical element and accompanied by a release of energy.
Generally, there are two (2) main types of nuclear reaction and these include:
- <u>Nuclear fission:</u> it involves the collision of a heavy atomic nucleus with a neutron, thereby causing a split and release of energy.
- <u>Nuclear fusion:</u> it involves the joining of two smaller nuclei of atoms to form a single massive or heavier (larger) nucleus with the release of energy.
In conclusion, nuclear fusion is best described as the process by which small nuclei combine into a larger nucleus, accompanied by a release of energy.

Precipitate is silver sulfate and the net ionic equation is
2Ag⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s)
<u>Explanation:</u>
The given reaction is the reaction of sodium sulfate with silver nitrate and as the reaction goes we will get the precipitate of Silver sulfate and the balanced reaction is given as,
Na₂SO₄ + 2 AgNO₃→ Ag₂SO₄↓ + 2 NaNO₃
Here silver sulfate is obtained as a precipitate.
Net ionic equation is the equation in which the ions involved in the reaction only taken into account that is ions forming precipitate, whereas the other ions are considered as spectator ions, ions do not involved in the reaction.
Here the net ionic equation is:
2Ag⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s)
Answer:
The answer to your question is below
Explanation:
Answer:
Magnetic: Magnet being pulled to a metal surface- non- contact force
Friction: skateboard slowing down on a rough surface- contact force
Gravity: Ball falling to the ground - non-contact force
Electrical: Charged balloon pulling up on arm hair - non- contact force
Tension (pull): people playing tug-of-war - contact force
Applied (push): a person pushing a toy car - contact force
Air resistance: wind pushing on the sail of a sailboat - contact force
Spring: springs being pushed together -contact force
Explanation:
A contact force is a type of force that can only act when two bodies touch other physically. Examples of this include a push or a pull.
A non-contact force is a type of force that can only act when two bodies do not touch other physically. Examples include; electric force, magnetic force, etc.
6.02x10^22 is one mole, so we can just say it's 1 mol HCl in 2.0 L of water. Molarity is mol/L, so 1 mol/2 L is 0.5 mol/L or 0.5 M. Make sense?
