Answer:
Explanation:
Reaction rate is a measure of the speed of a chemical reaction. There are many theories that have been put forward to explain reaction rates. One of which is the collision theory.
The collision theory postulates that for a reaction to occur, there must be collisions between reacting particles. This implies that the number of successful or effective collision of particles determines the rate of a chemical reaction. For a collision to be successful, the particles must be properly oriented and equiped with adequate energy for the reaction.
One of the key component of the energy required for effective collision is temeperature. The number of effective collision and consequently the rate of chemical reactions are directly proportional to the temperature at which the reaction occurs. With increasing temperature, the activation energy becomes activated and the number of collision increases.
Answer:
Long fur
Explanation:
Long fur is an adaption for the tundra because it is cold and snowy in the tundra, so therefore long fur is an adaption

Answer: Option D) Saturated
Explanation:
A solution is said to be saturated when it contains as much solute as it can dissolve at that temperature. Hence, if more solute is added, it will not dissolve.
Thus, a saturated solution has the maximum amount of solute that will dissolve in a solvent.
Answer:
13
Explanation:
1 proton/neutron has an atomic mass of 1. We ignore the electrons because they are too small. Protons and Neutrons have the same atomic mass, therefore the answer s 6+7=13
