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).
10-7.5=2.5, 2.5/2=1.25, 7.5+1.25=8.75
Answer:
D
its wings deflect air downward, and the air pushes the plane upward.
Explanation:
According to Newtons third law of motion for every action there is an equal and opposite reaction.
the wings in the plane are designed in such way that the air flowing on the wing is deflected downwards as a result there is a lift produced on the plane due to Newtons third law of motion.
The milk of magnesia is a
suspension of magnesium hydroxide in water, which is a strong base that is used
to neutralize excess stomach acid. The presence of stomach acid or hydrochloric
acid (HCl) that is known to be a strong acid will react with the strong base and
neutralization reaction occurs since conjugate partners produced negligible
strength where the products are a salt and water.
