How many atoms are in 4 Al2(SO3)3

Chemistry
1 answer:
scZoUnD [109]3 years ago
4 0

There are 337.23 × 10²³ atoms in 4 moles of aluminum sulfite Al₂(SO₃)₃.

Explanation:

The questions ask how many atoms are in 4 moles of aluminum sulfite Al₂(SO₃)₃?

To answer this we use the Avogadro's number to devise the following reasoning:

if in        1 mole of Al₂(SO₃)₃ there are 14 × 6.022 × 10²³ atoms

then in  4 moles of Al₂(SO₃)₃ there are X  atoms

X = (4 × 14 × 6.022 × 10²³) / 1 = 337.23 × 10²³ atoms

How do you determine valence electrons of a metal? A non Metal?
Harlamova29_29 [7]

Answer:

Check the electronic configuration of elements.

Explanation:

▪Valence electrons are the elwctrons present in the outermost shell of any element.

For example,

Electronic Configuration of Sodium = 2,8,1

Here , Sodium has 1 valence electrons.

▪Valency of an element is the total no. of electrons to be gained/losed in order to achieve duplet/octate state.

For example,

Electronic configuration of Sodium = 2,8,1

Sodium can achieve octate state either by losing 1 electron or gaining 7 electrons. But losing 1 electron is eay than gaining 7 electrons. So Valency of Sodium = +1

☆Metals have 1 or 2 or 3 valence electrons.

☆Non metals have 4 or 5 or 6 or 7 valence electrons.

☆Noble gases tend to stay in duplet/octate state i.e they have 2 or 8 valence electrons.
