<span>A 18 M solution of an acid that ionizes only slightly in solution would be termed
concentrated and weak. The concentration of the acid is high. The acid which dissociates partially in water is a weak acid.
</span><span>Calculate the [H^+] for the aqueous solution in which [OH^-] is 1 x10^-9. Is this solution acidic, basic or neutral. To determine [H+] use:
1x10^-14 = [OH-][H+]
solve for [H+]
[H+] = 1x10^-14/1x10^-9
= 1x10^-5</span>

Answer:
21.4 L
Explanation:
Given data:
Volume of carbon dioxide produced = ?
Volume of oxygen = 37.4 L
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
It is known that,
1 mole = 22.414 L
There are 7 moles of oxygen = 7×22.414 = 156.9 L
There are 4 moles of carbon dioxide = 4×22.414 = 89.66 L
Now we will compare:
O₂ : CO₂
156.9 : 89.66
37.4 : 89.66/156.9×37.4 = 21.4 L
So from 37.4 L of oxygen 21.4 L of carbon dioxide is produced.
Answer:
The large the atomic radius the more the metallic character of elements
Explanation:
The atomic radius is related to the metallic character in a way that the larger the atomic radius, the more metallic a body becomes.
Therefore, as we go down a group, metallic character increases.
- Metallic character relies on the ability and willingness of an atom to share its valence electrons.
- As the size of an atom becomes large, the more metallic it is and the more its metallic character.
- In some other cases this character is known as electropositivity.
