Answer:
D. 8.3 x 10-4
Explanation:
Hello!
In this case, since the rate law is written solving for the rate constant as:
Thus, we plug the rate and concentrations to obtain:
Therefore, the answer would be D. 8.3 x 10-4
Best regards!
Balanced chemical reaction: 2CH₄(g) ⇄ C₂H₂(g) + 3H₂(g).
1) In a chemical reaction, chemical equilibrium is the state in which both reactants (methane CH₄) and products (ethyne C₂H₂ and hydrogen H₂) are present in concentrations which have no further tendency to change with time.
2) At equilibrium, both the forward and reverse reactions are still occurring.
3) Reaction rates of the forward and backward reactions are equal and there are no changes in the concentrations of the reactants and products.
Answer:
No
Explanation:
A white dwarf has a higher surface temperature than a red giant.
The majority of wind turbines consist of three blades mounted to a tower made from tubular steel. There are less common varieties with two blades, or with concrete or steel lattice towers. At 100 feet or more above the ground, the tower allows the turbine to take advantage of faster wind speeds found at higher altitudes.
Turbines catch the wind's energy with their propeller-like blades, which act much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller. So therefore your answer would be A.

<span>Answer:
1.6 atm.
pV/T = constant.
(1.25 * 3.0)/(273+29) <-- work in Kelvin
This gives you the constant.
Then you want p
So p = (T*constant)/V
= (284*0.0124)/2.2
I get = 1.6atm</span>
