Can you write the formula for and indicate the charge on each of the following ions: sodium ion, aluminum ion, chloride ion, nit

Anettt [7]

If the ion is named by (element-name) + ion, it is the element with a positive charge.
This means:
Sodium ion: Na(1+)
Aluminum ion: Al(3+)
If the ion is named by (element-prefix)+ide, then it has a negative charge.
This means:
Chloride: Cl(1-)
Nitride: N(3-)
Finally, if it has roman numerals after the name, that is the amount of positive charge the ion has.
Therefore:
Iron (II): Fe(2+)
Iron(III): Fe(3+)

At a certain temperature, 0.3411 0.3411 mol of N 2 N2 and 1.661 1.661 mol of H 2 H2 are placed in a 2.50 2.50 L container. N 2 (

Sveta_85 [38]

<u>Answer:</u> The equilibrium constant for the above reaction is 1.31

<u>Explanation:</u>

We are given:

Initial moles of nitrogen gas = 0.3411 moles

Initial moles of hydrogen gas = 1.661 moles

Equilibrium moles of nitrogen gas = 0.2001 moles

For the given chemical reaction:

$N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)$

<u>Initial:</u> 0.3411 1.661

<u>At eqllm:</u> 0.3411-x 1.661-3x 2x

Evaluating for 'x', we get:

$\Rightarrow (0.3411-x)=0.2001\\\\\Rightarrow x=0.3411-0.2001=0.141$

Volume of the container = 2.50 L

The expression of $K_c$ for the above equation follows:

$K_c=\frac{[NH_3]^2}{[N_2]\times [H_2]^3}$

We are given:

$[NH_3]=\frac{2\times 0.141}{2.50}=0.1128M$

$[N_2]=\frac{0.2001}{2.5}=0.08004M$

$[H_2]=\frac{1.661-(3\times 0.141)}{2.5}=0.4952M$

Putting values in above expression, we get:

$K_c=\frac{(0.1128)^2}{0.08004\times (0.4952)^3}\\\\K_c=1.31$

Hence, the equilibrium constant for the above reaction is 1.31

In general, what do you think a subscript in a chemical formula tells you

Vsevolod [243]

Answer:

In the most simplest of words: The number of atoms in a molecule

ex) c6h12o6

There are 6 carbon atoms and oxygen atoms, 12 hydrogen atoms

Another example NH4

there are 1 nitrogen atoms and 4 hydrogen atom

Hope that answers your question
