fish give off the compound ammonia which has a pH above 7 to which class of compounds does ammonia belong
1 answer:
<span><u><em>Answer:</em></u>
The compound ammonia given by fish is alkaline
<u><em>Explanation:</em></u>
<u>We can classify elements/compounds based on their pH values into three types:</u>
<u>acids:</u> these are compounds having pH value lower than 7
<u>neutral:</u> these are compounds having pH value equal to 7
<u>alkalies:</u> these are compounds having pH values higher than 7
This is shown in the attached image
We are given that the pH of the compound ammonia generated by the fish is above 7.
According to the above explanation, compound ammonia would be an alkaline compound.
Hope this helps :)</span>

Answer:
A. From 25,0 g of aluminium you will produce 0,927 moles of aluminium chloride
B. From 30,0 g of chlorine gas you will produce: 0,282 moles of aluminium chloride
Explanation:
a. The reaction that you have in this problem is:
3 Cl₂ + 2 Al → 2 AlCl₃
25,0 g of aluminium are:
25,0 ₓ = 0,927 moles
As Al:AlCl₃ ratio is 1, from 25,0 g of aluminium you will produce: <em>0,927 moles of aluminium chloride</em>
b. 30,0 g of chlorine gas are:
30,0 ₓ = 0,423 moles of Cl₂
As Cl₂:AlCl₃ ratio is ³/₂:
0,423 moles of Cl₂ ₓ = <em>0,282 moles of aluminium chloride</em>
Thus, from 30,0 g of chlorine gas you will produce: <em>0,282 moles of aluminium chloride</em>
<em></em>
