How many ATOMS of sulfur are present in 2.30 moles of sulfur trioxide?

Chemistry
1 answer:
zysi [14]3 years ago
8 0

Answer:

1.39 Atoms

Explanation:

When converting from moles to atoms, multiply the number of moles by Avogadro's number

Multiply 2.30 moles by Avogadro's number (6.022*10^23)

= 1.3851 Atoms

=1.39 Atoms (sigfig)

SIZIF [17.4K]

Answer:

The possible valances can be determined by electron configuration and electron negativity

Good Luck even though this was asked 2 weeks ago

Explanation:

All atoms strive for stability. The optima electron configuration is the electron configuration of the VIII A family or inert gases.

Look at the electron configuration of the nonmetal and how many more electrons the nonmetal needs to achieve the stable electron configuration of the inert gases. Non metals tend to be negative in nature and gain electrons. ( They are oxidizing agents)

For example Florine atomic number 9 needs one more electron to reach a valance number of 8 electrons to equal Neon atomic number 10. Hence Flowrine has a valance of -1

Oxygen atomic number 8 needs two more electrons to reach a valance number of 8 electrons to equal Neon atomic number 10. Hence Oxygen has a valance charge of -2.

Non metals with a low electron negativity will lose electrons when reacting with another non metal that has a higher electron negativity. When the non metal forms an ion it is necessary to look at the electron structure to determine how many electrons the element can lose to gain stability.

For example Chlorine which is normally -1 like Florine when it combines with oxygen can be +1, +3, + 5 or +7. It can lose its one unpaired electron, or combinations of the unpaired electron and sets of the three pairs of electrons.

PLEASE HELP!!! ILL GIVE YOU BRAINLIEST!!!!
saul85 [17]

Answer:

A.

Explanation:

It would be A. because the question is asking how the harmful chemicals have an effect on the environment. This answer also proves that even though we don't mean to harm the environment it still happens because we are using these chemicals for things in our daily life.
