A physical change.
Physical change = can be reverted + doesn't change substance
Chemical = changes substance
Answer:
110k because 2 x 110 =220
Answer:
Explanation: A compound with the empirical formula SO has a molecular weight of 96.13
The major portion of an atomic mass consists of neutrons and protons.
Answer: neutrons and protons
Answer: As temperature increases, the number of collisions increases and the energy of the collisions increases.
Explanation:
According to collision theory, for a reaction to take place it is necessary to have collisions between the reacting species or atoms.
A collision will only be effective if species coming together have a certain minimum value of internal energy equal to the activation energy of the reaction.
More is the number of collisions taking place in a chemical reaction more will be the kinetic energy of its molecules. As kinetic energy is the energy acquired due to motion of atoms or a substance.
Also, collisions increases with increase in temperature as:

Kinetic energy is directly proportional to temperature. So, more is the temperature more will be energy of molecules.
Thus, we can conclude that as temperature increases, the number of collisions increases and the energy of the collisions increases.
