Answer:
when the forward and reverse reactions occur at equal rates.
chemical reaction is in equilibrium when the concentrations of reactants and products are constant - their ratio does not vary.
The factor that does not influence stream velocity is DISCHARGE.
Stream velocity refers to the speed with which the water in a stream is flowing. The factors which affect stream velocity include channel size, channel shape, turbulent flow and gradient.
Answer:
Explanation:
The speed of sound in the air mainly depends on temperature. At high altitudes, where it is much colder, sound travels slower. The higher the temperature, the faster the air molecules are moving to begin with, and the quicker they bump into each other as a sound wave passes through.
Carbon can react with oxygen to form carbon dioxide. Which of the following statements about this chemical change is true? ... Carbon and oxygen atoms are destroyed as new atoms are formed. Carbon and oxygen atoms have the same properties as molecules of carbon dioxide.
Answer:
25 coolers are need to be produce and sell in order to minimize the cost.
Explanation:
..[1]
Differentiating the given expression with respect to dx.
Putting ,
x = 25
Taking second derivative of expression [1]
(minima)
25 coolers are need to be produce and sell in order to minimize the cost.
