(3) the forward reaction rate is equal to the reverse reaction rate
hope this helps!
NH3 is a gas at room temperature. Solutions of "ammonia" are made by bubbling NH3 through water, so there's no "pure ammonia" unless you are talking about the gas.
Answer:
it is 50
if I m right pls mark me brainliest
D. Cannot be broken is correct!
A scientific law cannot be broken is correct because it has been tested so many times it's a known fact. For example Gravity is a scientific law.
The rate of change of the temperature of the Earth's surface is given to,
90°F/mile
To determine the temperature x miles away from the surface, we multiply the depth by the given rate. This will give us the answer of,
T = (90°F/mile)(90 mile)
= 8100°F
Thus, the temperature 90 miles deep in the Earth's surface is equal to 8100°F.
