Adding and subtracting with scientific notation may require more care, because the rule for adding and subtracting exponential expressions is that the expressions must havelike terms<span>. Remember that to be </span>like terms<span>, two expressions must have exactly the same base numbers to exactly the same powers. Thinking about decimal arithmetic, the requirement that we have the same powers makes sense, because that guarantees that all of the place values are lined up properly.</span>
Answer:
A neutralized solution in chemistry refers to the reaction between an acid and base that results in a neutral balance, or a measure of 7 on the pH scale.
Explanation:
Answer/Explanation:
A theory has lots of scientific evidence to back it up. We know this to be true based on lots of different diseases and studies of their spread.
A hypothesis is more of a starting point - an educated guess based on limited evidence. It requires further testing before becoming a theory.
A law is something that can be generalized to lots of contexts, and is universal. Such as the law of thermodynamics.
Similarities:
they both made sediment into soil
they both form the earth
they both made sediments have cracks
differences:
physical is reliant usually on contact with atmospheric condition
chemical transforms rocks into sediments while physical only breaks it down
chemical uses chemical reactions
