What is the mass of one mole of popcorn kernels? (sig fig hint: consider the precision of avogadro's number to determine the cor

svetlana [45]

Since the mass of a single popcorn kernel is not given, lets us assume that it is 1 gram

Now:

1 mole of popcorn kernels contain $6.023 * 10^{23}$ kernels

Since:

1 kernel weighs 1 gram

Then,

$1 mole = 6.023 *10^{23}$ kernels would weigh $6.023 * 10^{23}$ grams

Amphetamine was developed initially as a substitute for a closely-related chemical derived from the Chinese herb ma huang. That chemical is Ephedrine.

<h3>What is Ephedrine?</h3>

Ephedrine is a stimulant medication that can be considered an amine chemical compound and substituted amphetamine.

Ephedrine is used in sports to stimulate the central nervous system (C_NS) and as energy supplier.

Ep_hedrine use is prohibited and chronic usage of this substance may have problems the health.

When metallic aluminum is added to a solution containing iron(II) sulfate a reaction occurs. What species is being oxidized in t

REY [17]

<u>Answer:</u> Aluminium is getting oxidized in the given chemical reaction.

<u>Explanation:</u>

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

$X\rightarrow X^{n+}+ne^-$

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

For the given chemical reaction:

$2Al(s)+3FeSO_4(aq.)\rightarrow Al_2(SO_4)_3(aq.)+3Fe(s)$

The half cell reactions for the above reaction follows:

<u>Oxidation half reaction:</u> $Al\rightarrow Al^{3+}+3e^-$

<u>Reduction half reaction:</u> $Fe^{2+}+2e^-\rightarrow Fe$

As, aluminium is loosing 3 electrons to form aluminium cation. Thus, it is getting oxidized. Iron is gaining 2 electrons to form iron anion. Thus, it is getting reduced.

Hence, the oxidized species of the given reaction is aluminium.
