What is the speed of a car that travels a distance of 520 kilometers in 12 hours? 0.43 km/hr 0.023 km/hr 62.4 kmhr 43 km/hr

The correct answer would be 43 km/hr.

Speed is defined as the rate at which a person or a thing is moving.

It can be calculated by dividing total distance traveled by the total time taken to cover that distance.

Speed = Distance / time

It is provided that a car traveled 520 kilometers in 12 hours.

So, the distance = 520 kilometers

Time = 12 hours

Speed = 520/12 kilometers per hour

= 43.33 kilometers per hour.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
