A theory will eventually become a law if there is enough evidence to support it

True or False

Answers

Answer:

True.

Since the words hypothesis and law have such diverse implications within the dialect of science, it is often a troublesome address to reply, so instep, I'll begin by giving you some similar questions to answer. How flawlessly do you have got to construct a house so that it'll become a single brick? How well do you have got to type in a whole dictionary to alter it into a single word? What would you have got to do to alter a whole ensemble into a single note? If you're considering that those questions do not make much sense, at that point you're feeling exceptionally much like a researcher who has been inquired "How much proof does it take for a hypothesis to graduate to being a law?" A house is made up of numerous bricks, sheets, nails, windows, entryways, concrete, etc. A lexicon is made up of thousands of distinctive words, and a orchestra can effortlessly have thousands of notes that all fit together in fair the proper way to deliver satisfying music. Within the same way, hypotheses are based on a assortment of logical laws, actualities, testing, and other evidence, all fit together in a way that offers an explanation of how some part of the universe works.

HELP ITS DUE TODAY put the number by which one you answer!!!!

Answers

1- Reactants (H = 2, O = 2)
Products (H = 2, O = 0)
2- Reactants (P = 4, O = 2)
Products (P = 2, O = 3)

So basically if it was H20, then there is 2 Hydrogen because the two is in front of the H and there isn’t a 2 in front of Oxygen.
However if it was H2O2, then there is two hydrogen and two oxygen because there is a two on both of the symbols which indicates how much reactants/products there is.
