1. Benedict’s solution is the testing reagent for monosaccharides in experiment 1. Why were you instructed to heat the Benedict’s solution by itself in test tube 1?

Test tube 1 would serve as a negative control for the experiment.

Explanation:

Heating of Benedict’s solution in the presence of monosaccharides would change the color. However, when it has no monosaccharides present, the color will stay the same. So, in any experiment where you want to test the presence of monosaccharides (reducing sugars), you are supposed to heat the Benedict’s solution alone too so that you know that there was no contamination in the solution itself and then you can compare the results of test samples.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
