Answer:
Increasing the temperature
Increasing particle size
Explanation:
Increasing the temperature allows for particles and molecules to move faster (because there is an increase in energy) and allows for more collisions.
∴ Increasing the temperature would be an answer.
Increasing the particle size allows for more surface area and a greater chance for particles to collide with each other.
∴ Increasing particle size would be an answer.

Answer:
The valence shell (the 3s and 3p sublevels) contains six electrons, but it needs eight to become stable. Think of the octet rule. Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of 2− , with the symbol S2− .

it was first recorded by England's Sir Francis Bacon (1561-1626)
Answer: sulfuric acid
Explanation:
sulfuric acid always produces salts that end in sulfate and contain the sulfate ion, SO.
Answer:
The correct answer is option C.
Explanation:
r = resultant vector
y = vertical component of vector
x = horizontal component of vector
We have :
The vertical component of a vector is 40 N and its horizontal component is 25 N.
x = 25 N
y = 40 N
47.2 N is the magnitude of the vector.
