An atom gains an electron from another atom. Hence, option B is the correct answer.
<h3>What is an atom?</h3>
An atom is a particle of matter that uniquely defines a chemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons.
When an atom shares electrons with another atom then it results in the formation of a covalent bond.
Whereas when an atom transfer electrons from one atom to another then it results in the formation of an ionic bond.
When the nucleus of an atom splits then it represents a nuclear fission reaction and energy is released during this process.
Hence, option B is the correct answer.

Single and Double Replacement reactions are exactly as they sound - they “replace” one or two components, depending on the type, with something else obtained in the reaction.
1. This is a double replacement reaction - see that the SO4 and the OH groups are trading what they’re paired with? OH starts paired with Aluminum, and ends up paired to the Hydrogen, and the SO4 starts with the Hydrogen, but ends up with the Aluminum. Two things being replaced - a double replacement reaction.
2. This is a single replacement reaction - Iron replaces the Hydrogen through the reaction, leaving the Hydrogen inbound afterwards; one thing being replaced - a single replacement reaction.
3. Like 1, this is a double replacement reaction - Fluorine and Oxygen trade partners. Two things being replaced - a double replacement reaction.
Number 4 isn’t complete, and I’m not sure about the goal of the practice problems, so I hope this helps enough to finish the work!
Answer:
Around worm because it gets bebefits such as food and habitat without killing its host..
Answer:
The Lassaigne's test, also known as
the sodium fusion test, is used in
elemental analysis to determine the
presenceof foreign elements,
specifically halogens, nitrogen, and
sulfur, in an organic compound.

Answer:
Activity 1: Since the only forces apposing the upward movement of the load are gravity and air resistance the formulas of which can both be solved with weight then with constant variables for gravity and air, effort IS directly proportional to weight.
Activity 2:
Inclined plane.
to make lifting easier; raising or lowering a load.
Explanation:
