Answer:
A
Explanation:
When a reaction happens some of the reactants mass is released as energy so the mass of the product would be less
Answer:
See image attached
Explanation:
Ibuprofen is a chiral compound. 'Chiral' means that it has the ability to rotate plane polarised light owing to the presence of an asymmetrically substituted carbon atom. There are two known stereoisomers of the compound; the S- stereoisomer and the R-stereoisomer. The both are shown using wedge and dash perspectives in the image attached.
Only the S- stereoisomer is active as a drug. The R-stereoisomer is gradually converted into the S-stereoisomer in the body. The drug may also be given as a racemic mixture.
An Ionic bond is when you have a metal and a nonmetal element bonded together. In this kind of bonds, the metal atom takes electrons from the nonmetal. on other words, this bond involves the gaining and losing of electrons. The atom that receives the electrons becomes an anion (negatively charged ion) and the one that loses them becomes the cation (positively charged ion)
A covalent bond is a bond created between two nonmetals element. In here, both atoms share the electrons.
Both bonds involve interaction between atoms.
Answer:
The answer is THEORY! Hope it helps!
Answer:
The correct answer is working theories.
Explanation:
The theories that combine skills, knowledge, and attitudes taken from the experiences with places, individuals, and things are known as working theories. These theories function in monitoring events, making sense of experience, and solving issues, and create in order to turn more applicable and useful, more interconnected, and elaborate. The working theories are supported by certain proofs, however, they are not the basis for a field study yet.
