Answer:
As the description in the question shows, Kaley is taking careful and regular measurements. Hence, her experimental method is correct.
Kaley has also developed a hypothesis and the experiment she conducted is also valid hence there is no problem in these steps.
There is no mistake being done by her in depicting the results of the experiment.
Hence, the only thing which we can say is missing from the experiment is the past researches which scientists might have made on this topic.
Explanation:
Answer:
When an acid and a base are placed together, they react to neautralise the acid and base properties, thus making a salt.
Explanation:
The compound formed by the caption of the base and the anion of the acid is called a salt.
Answer:
Pascal is the most common unit for measuring pressure
The average sea level pressure is 1013 mbar
2 atoms of Al
3 of S
4*3=12 of O
so total= 17
C2H6O + O2 ---> C2H4O2 + H2O
using the molar masses:-
24+ 6 + 16 g of C2H6O produces 24 + 4 + 32 g C2H4O2 (theoretical)
46 g produces 60g
60 g C2H4O2 is produced from 46g C2H6O
1g . .................................46/60 g
700g ................................. (46/60) * 700 Theoretically
But as the yield is only 7.5%
the required amount is ((46/60) * 700 ) / 0.075 = 7155.56 g
= 7.156 kg to nearest gram. Answer
