Answer:
C6 H10 O5+ 6O2-----> 6CO2+5H2O+heat
Explanation:
There are 6 carbon atoms in reactants to balance you put coefficient 6.
This makes the oxygen in CO2 12 so to balance put 6 in oxygen in reactants.
There are 10 hydrogen atoms in reactants to balance you put 5 in front of H2O in products.
If u recheck: 6 C atoms in reactants, 6 C atoms in products.
10 H atoms in reactants, 10 H atoms in products.
17 O atoms in reactants, 17 O atoms in products.
We have to explain monochlorination.
Monochlorination is the process to introduce one chlorine atom in any organic compound.
Generally, monochlorination takes place by replacement of proton from organic compound. To do chlorination, Cl₂ or HCl is used as reagent.
Inntroduction of one Cl-atom in any organic molecule takes place through free radical mechanism.
The monochlorination of benzene is shown here:
Answer:
250 kJ
Explanation:
Step 1: Given data
- Work performed by the system (w): 145 kJ (By convention, when the system performs work on the surroundings, w > 0)
- Heat absorbed by the system (q): 105 kJ (By convention, when the system absorbs heat from the surroundings, q > 0)
Step 2: Calculate the change in the internal energy of the system
The internal energy of a thermodynamic system is the energy contained within it. We can calculate the change in the internal energy (ΔE°) using the following expression.
ΔE° = q + w
ΔE° = 105 kJ + 145 kJ = 250 kJ
The array will be created with the elements equal to null.
