Hunter is in lab. He clears a spot on his lab bench to start working. He also puts his lab coat and goggles on. He then identifies where all of the safety equipment is. He notices his station is next to the fume hood, which ventilates the chemicals stored there. The noise of the fume hood was bothersome, so Hunter turned it off. Which could be an error in his set-up? He should not turn off the fume hood. He should wait to put on his coat until after the directions are given. He should wait to put on his goggles until after the directions are given. He should not sit next to the fume hood.

He should not turn off the fume hood.

Explanation:

According to this question, Hunter is in a laboratory where he is about to commence work. He starts by adhering to some laboratory safety rules including putting on his lab coat and goggles. However, he was bothered by the noise of the fume hood, which was close to his station. He then decided to switch/turn it off.

The "TURNING OFF OF THE FUME HOOD" is Hunter's error in this experimental set-up. This is because the fume hood is a laboratory safety device that helps prevent the inhalation of harmful gases by laboratory workers. The fume hood is a ventilated compartment which ventilates i.e. passes out, the chemicals stored there.

Every experiment involving chemicals should be performed in the fume hood in order to curb the escape of fumes from this reactions. Hence, TURNING THE FUME HOOD OFF means that one of the safety laboratory protocols has been defaulted.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
