The proper science is validated by Experimentation and Testing .
What is experiment and testing?
Experiment is performed to support or Refuge a hypothesis which is given by someone.
Test is to figure out what we expect and what we have observed.
So , the proper validation of science is Experiment and testing because science is all about hypothesis, discoveries if want to prove them right or wrong we have to perform experiment and test .

DescriptionA chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.
Answer:
Biochemical compounds make up the cells and other structure of organism and carry out life processes.Carbon is the basic of all biochemical compounds so carbon carried life process on the earth

Explanation:
<span>A reversible reaction is a chemical change in which the products can be converted back to the original reactants under suitable conditions.</span><span> In a reversible reaction, changing the reaction conditions e.g. concentration, pressure or temperature will change the net direction the reaction goes i.e. more to the right (forward) or more to left (backward).<span>It also means a reversible reaction does not go to completion in either direction and all components, original reactants or ensuing products, ALL co-exist in the reaction mixture (see notes on chemical equilibrium).</span></span><span><span>This means the reaction can go in either direction i.e.</span><span> <span>A + B ==> C + D or C + D ==> A + B</span></span></span><span><span>A reversible reaction is shown by the sign ,</span><span> <span>a half-arrow to the right (direction of forward reaction), </span><span>and a half-arrow to the left (direction of backward reaction).</span><span>It is really important you understand that the terms right & left AND forward & backward are used in the context of how the equation is presented.</span></span></span><span><span>Most reactions are not reversible (irreversible) and have the usual complete arrow only pointing to the right.</span>
