The heat of the reaction, in kJ, when 4.18 g of the hydrocarbon are combusted 775.70 kJ.
The heat energy is given as :
q = m c ΔT + Ccal ΔT
q = ( 974 g× 4.184 ×6.9) + 624 ×6.9
q = 32424.59 J
moles of hydrocarbon = 0.0418 mol
heat of combustion = 32424.59 J / 0.0418 mol
= 775707.89 J
= 775.70 kJ
Thus, A 4.18 g sample of a hydrocarbon is combusted in a bomb calorimeter that contains 974 g of water. the temperature of the water increases by 6.9 °C when the hydrocarbon is combusted. the calorimeter constant for the calorimeter was determined to be 624 J/°C. what is the heat of the reaction is 775.70 kJ.

Answer:
A clinical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own.
<h3>A. an acidic............</h3>
When sucrose is hydrolyzed, <u>two reducing groups</u> will be created as the glycosidic linkage is broken. Hydrolyzed sucrose <u>will</u> give a positive Benedict's test. Hydrolysis can be achieved by adding <u>strong acids or enzymes.</u>
<h3>How is sucrose hydrolyzed in the body?</h3>
The reaction that breaks bonds and releases energy is called hydrolysis. It is a significant biological process that causes energy to be released from within our bodies. The human small intestine contains the -glucosidase enzyme sucrase, which hydrolyzes sucrose into its component monosaccharides fructose and glucose. In the brush boundary of the upper gastrointestinal system, roughly 10–25% of the fructose is converted to glucose.
