Answer:

HEAT REQUIRED TO RAISE THE TEMPERATURE OF 179 ACETIC ACID FROM 25 °C TO 82.7°C IS 21 100j OR 21.1 kJ

Explanation:

Heat = mcΔT

m = 179 g

C =  2.043 J.g-1K-1

ΔT = ( 82.70 - 25 ) = 57.7°C

Heat = 179 * 2.043 * 57.7

Heat = 21, 100.72 J

Heat ≅ 21.1 kJ

lianna [129]
The reaction equation:
2Li + O → Li₂O

Molar ratio of Li to Li₂O is:
2 : 1
So if 3.03 moles of Li are present:
2/1 = 3.03 / x
x = 1.515 moles of Li₂O will be produced.

AnnZ [28]
The given reaction: 
<span>ch3ch2cooh (aq) ↔ ch3ch2coo- (aq) + h+ (aq)
is called a reversible reaction.

This means that, the reaction does not reach an end point.
In this type of reactions, reactants react together to form products, while products combine together to form reactants.
So, the reaction proceeds in both direction forming both reactants and products.</span>
