Hydrogen atoms one outer electron so would be placed in group 1. However all group 1 elements are metals and elements in the same group have similar properties. Hydrogen is a non-metal and does not behave in the same way as the other group 1 elements, so that is why it is on its own.
There would be no net movement of glucose
The given statement is wrong. Glucose solutions are not electrolytes and therefore do not conduct electricity.
Is sodium chloride a good conductor of electricity? Simply by dissolving or dissolving it in water, it cannot conduct electricity as a solid.
Saline contains Na+ and Cl- ions. If ions are present in the solution, these ions can move through the solution and carry an electric current. Pure water and sugar solutions do not contain significant ions. Sugar molecules do not break down into ions when dissolved.
When glucose is added to water, it dissolves readily but does not dissociate into ions. Therefore, a glucose solution is not an electrolyte and is not a conductor of electricity.
Substances that dissolve in water to form a conductive solution are called electrolytes. Substances that dissolve in non-conductive solutions are called non-electrolytes. All soluble ionic compounds are electrolytes.

Answer:
176984.38J
Explanation:
E = mC∆T
Where E is the energy in joules
M is the mass of water
C is the specific heat capacity of water =4.184J/g°C
It is known that it will take 4.184J of energy to change the temperature of water by one degree Celsius.
∆T = 98.6°c - 5.4°c
= 93.2°c
∆H = 454.3g × 4.18J/g°C × 93.2°c
= 176984.3768
176984.38J
