Explanation:
Since, aluminium chloride is an eye and skin irritant. Therefore, it is better to follow safety measures while dealing with such a chemical.
Hence, it is good to wear a lab coat while working in a laboratory and wear chemical resistant gloves so that our skin does not come in contact with the chemical.
Also, safety glasses will prevent the eyes if there is spurting of chemical.
Thus, we can conclude that chemical-resistant gloves, a lab coat, and safety glasses will prevent you from coming into contact with the given hazard.
Answer:
the heat flows from the hand to the ice cream
Explanation:
we produce body heat therefore it moves to the ice cream also there is no possible way the heat could move from the ice cream because the ice cream is cold
The formula of citric acid is:
CO2H

HO - C - CH2CO2H

C - CH2 CO2H
I bolded the 4 hydrogens that can be subsituted by sodium.
Three of those hydrogens belong to carboxyl group (- CO2H) and one to a hydroxyl group (- OH).
You need to take into account that 4 H will form 2 H2 molecules.
So, the answer is that 2 moles of molecules will be formed from 1 mole of citric acid molecules.
Answer: option (A)
Explanation: The convection current is generates in the mantle due to the heat radiated from the core of the earth. Due to this convection current, the lithospheric plates moves as the upper part of the mantle known as the asthenosphere, is the region which is viscous in nature and drives the plates to move. This is a repeating cycle that constantly forces the plates to move.
Thus the correct answer is option (A).
