Answer:
a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction
Answer:
Story in chemical reaction is about the general issue of bond formation and bond breaking where by the energy required to break bond of reactant to form product is called activation energy
Scientist study the whole process and bring law of law conservation of mass,law of definite proportion (Louis proust 1799),law of multiple proportion (Dalton 1803) law of reciprocal proportion(Ritcher1792)
Story about electric current
It's about rate of flow of electric charge in given point
Inshort discovered by the work of Faraday and Alessandro Volta1803italian physics
B) measure the temperature at noon everyday
P.S This is Science
Every action has an equal but opposite reaction.
So, if I push on a door with a force of 5 N, the door will push back on me with a force of 5 N.
Newton's third law states that all forces occur in pairs such that if one object exerts a force on another object, then the second object exerts an equal and opposite force on the first.
Summed up, this means that "For every reaction, there is an equal and opposite reaction."
I hope this helped!
Answer:
Synthesis reaction
Explanation:
A synthesis reaction involves two or more reactants combining to form a single product.
4Fe + 3O2 —> 2Fe2O3
From the above reaction, the two reactants combine to form a single product. This is clearly a synthesis reaction.
b) lighting a match from a matchbook
c) cutting snowflakes out of paper
d) melting butter for popcorn
