Group-8 elements are inert and possess
Artemon [7]

Answer:

Group 8 elements are inert and possess :

1. Low Boiling Points

2. High ionization energies

3. Electronegativities is very low

4. No color, odor

Explanation:

Group 8 elements are also called as Noble Gases. They are unreactive.

They have low boiling points means they remains monoatomic  at room temperature.  Having high ionization energy means that it is very difficult to remove an electron from its valence shell.

How many moles of H3PO4 would produce 12 moles of water in this reaction? ЗKOH + H3PO4 K3PO4 + 3H20
Olenka [21]

Answer:

4 moles of H₃PO₄

Explanation:

The reaction expression is given as;

     3KOH   + H₃PO₄   →   K₃PO₄   +  3H₂O

Number of moles of water  =  12moles

Unknown:

Number of moles of H₃PO₄ = ?

Solution:

 From the balanced reaction expression we see that;

          3 moles of water is produced from 1 mole of H₃PO₄

So;    12 moles of water would be produced from \frac{12}{3} = 4 moles of H₃PO₄

The equilibrium of 2H 2 O(g) 2H 2 (g) + O 2 (g) at 2,000 K has a Keq value of 5.31 x 10-10. What is the Keq expression for this
maks197457 [2]
Answer is: Keq expression for this system is Keq = <span>[O</span>₂<span> ]</span> · [H₂<span>]</span>² ÷  [H₂O<span>]</span>².<span>
Chemical reaction: 2H</span>₂O(g) ⇄ O₂(g) + 2H₂(g).
The equilibrium constant<span> (Keq) is a ratio of the concentration of the products (in this reaction oxygen and hydrogen) to the concentration of the reactants (in this reaction water).</span>
