What is the purpose of finding oxidation states in the half-reaction method for balancing equations?

How much heat, in kJ, is required to raise the temperature of 50 g of water by 5.53°C? (Round to the nearest 10 kJ, and enter on

Triss [41]

Answer:

$Q=1.16kJ$

Explanation:

Hello,

in this case, the required heat to increase the water by 5.53 °C is computed by using the mass, heat capacity and change in temperature during the process:

$Q=mCp\Delta T$

Thus, for the given data we compute it in kJ:

$Q=50g*4.186\frac{J}{g*\°C}*(5.53\°C)*\frac{1kJ}{1000J} \\\\Q=1.16kJ$

Best regards.

What is the relishing hip between the chemical energy provided by the battery and the electrical energy produced according to th

Novay_Z [31]

Answer:

Equal

Explanation:

Energy is always conserved in the nature and it is an universal law. According to the law conservation of energy, it is said that energy can never be created out of something and we can never destroy and vanish any energy in any form. Energy in any form can only be transformed to some other forms of energy. This is known as conversion of energy.

In the context, the chemical energy that is produced by the battery and the electrical energy produced should be equal.

Carboxylic acids and alcohols react via dehydration and condensation to produce a/an _______ and water.

avanturin [10]

Answer:

ester

Explanation:

Carboxylic acids and alcohols react in the presence of strong acid to produce an ester and water. The two carbon chains come together, which is the condensation, and then water is generated, which is dehydration. The resulting compound is an ester.
