Answer:
Using blue and red litmus paper.
Explanation:
if we test all the solutions with blue and red litmus paper, we will know which solution is water and which solution is not water because blue and red litmus paper determined the pH of the solution. The pH of the water is neutral so it can't change its colour while on the other hand, the other solution change their colour due to acidic or basic nature of the solution so in this way we can determine the chemicals in the solution without tasting it.
Answer:
These examples could be written as chemical reactions, but are more generally considered to be endothermic or heat-absorbing processes: Melting ice cubes. Melting solid salts. ... Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.
Explanation:
Answer:
Digestive
Explanation:
It is necessary for the body to function so it is technically an organ
Answer:
Peropanamide participates in hydrogen bonding because it has the highest boiling point.
N, N-dimethyl formamide has the lowest boiling point due to the lack of hydrogen bonding
Explanation:
Compare N-methylacetamide with its amide isomers propanamide and N,N- dimethylformamide. Which do you predict has the highest boiling point? The lowest?
Peropanamide participates in hydrogen bonding because it has the highest boiling point.
N, N-dimethyl formamide has the lowest boiling point due to the lack of hydrogen bonding
It is C. An increase of temperature results in an increase in kinetic energy of the molecules of the substance. For example, in a gas the molecules will move about faster.
