Increase temperature = particle move faster
increase Concentration =more crowded so more collisions
Explanation:
when temperature increase,the particle gain kinetic energy which make the particles move faster hence more collisions.
if concentration increase,there will be more frequent collisions between the particles due to crowded
Answer:
1) 8 valence electrons are a full shell that makes the atom more stable.
Explanation:
Due to the octet rule, atoms tend to form compounds in ways that give them eight valence electrons and thus give them the electron configuration of a noble gas, making them stable.
When the total surface area of the solute particles is increased, the solute dissolves more rapidly. Breaking a solute into smaller pieces increases its surface area and increases its rate of solution. So, any answer with “as surface area increases, solid dissolves faster” would be correct. :)
Answer: The three end products of the oxidation-reduction reactions involved in metabolism are WATER, CARBON DIOXIDE and ATP.
Metabolism refers to the sum of all chemical reactions occurring in the body. It includes both catabolism and anabolism. Every metabolic reaction is characterized by oxidation-reduction reactions. The metabolic pathways include respiration, photosynthesis, etc. In all these reactions water is produced. In respiration CO2 is also a product. In general. in every metabolic reaction either an organic molecule is broken or synthesized producing CO2, water and energy.
