Answer:
The rate of appearance of hydrogen gas is 0.095 M/s.
Explanation:
Rate of the reaction is the change in concentration of of any one of the reactants or products per unit time.
Given:
The rate of disappearance of HBr = ![-\frac{d[HBr]}{dt}=0.190 M/s](https://tex.z-dn.net/?f=-%5Cfrac%7Bd%5BHBr%5D%7D%7Bdt%7D%3D0.190%20M%2Fs)
Rate of the reaction is given by:
![R=-\frac{1}{2}\frac{d[HBr]}{dt}=\frac{1}{1}\frac{d[H_2]}{dt}](https://tex.z-dn.net/?f=R%3D-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7Bd%5BHBr%5D%7D%7Bdt%7D%3D%5Cfrac%7B1%7D%7B1%7D%5Cfrac%7Bd%5BH_2%5D%7D%7Bdt%7D)
![R=-\frac{1}{2}\frac{d[HBr]}{dt}=\frac{1}{2}\times 0.190 M/s=0.095 M/s](https://tex.z-dn.net/?f=R%3D-%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7Bd%5BHBr%5D%7D%7Bdt%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%200.190%20M%2Fs%3D0.095%20M%2Fs)
Rate of appearance of the hydrogen gas:
![\frac{d[H_2]}{dt}=R =0.095 M/s](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BH_2%5D%7D%7Bdt%7D%3DR%20%3D0.095%20M%2Fs)
The rate of appearance of hydrogen gas is 0.095 M/s.
Answer:
Energy is converted in a hydroelectric plant as follows;
The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy
Explanation:
The water in an hydroelectric plant is given potential energy by building an artificial dam to raise the height of the water above the turbine
The high potential energy of the water is converted to kinetic energy which provides the power that turns the turbine transforming the kinetic energy of the water into rotational kinetic energy of the turbine by conservation of mechanical energy;
The shaft connected between the turbine and the generator, turns the generator by the mechanical energy of the turbine and as the generator turns in a magnetic field, electricity is produced by magnetic induction according to Faraday's law.
It gets huge. REALLY BIG....and tastes like jello....
Le Chatelier's principle states that when a change is brought to a system in equilibrium, the equilibrium will shift in a manner to reverse that change.
If the pressure is increased, the system will try to reduce the pressure. The only way it can do this is by producing less gas. Therefore, shifting the equilibrium to the left. Thus, the statement is true.
Answer: no tea is not a pure substances
Explanation:
A Tea is a solution of compounds in water, so it is not chemically pure. It is usually separated from tea leaves by filtration. B Because the composition of the solution is uniform throughout, it is a homogeneous mixture. ... A Aluminum oxide is a single, chemically pure compound.Sep 18, 2019
