The sample of smoke described above can be described as a heterogeneous mixture. This type of mixture do not have uniform properties and composition. So, getting a certain small sample would not represent the whole mixture since it does not have uniform composition.
Na2C03 is formed through the reaction of
NaOH and H2CO3 namely sodium hydroxide and carbonic acid
NaOH -> strong base
H2CO3-> weak acid
BE CAREFUL! If it is a controlled lab wear saftey equiptment. But it can blow up. So careful...
The answer is rounded off to 0.0278 mol C6H12O6
Answer:
The correct option is C.
Explanation:
If the system is present in the dynamic equilibrium, then the rate of sublimation of the NH4CI crystals is equal to the rate of production if the NH4CI vapors.
A dynamic equilibrium is defined as the reversible reaction repel to change its ratio of products, and reactants, but at equal rate substances keep moving between the chemicals, and there is no net change occurs.
So, the correct answer is option C. (The rate of sublimation of the NH4CI crystals is equal to the rate of solidification of the NH4CI vapors).
