Answer:
Kc = 1.35x10^7
Explanation:
Let's write the reaction again:
2R + A <------> 2Z Kp = 5.51x10^5
In order to know the value of Kc, we need to write the expression that relations the Kp with Kc which is:
Kp = Kc * (RT)^Δn (1)
Where:
R: 0.082 L atm/ K mol
Δn: difference between the coefficients of the reaction
Kc: equilibrium constant
T: temperature in K
Now, from the equation (1) we can solve for Kc:
Kc = Kp / (RT)^Δn (2)
Now, before do any calculations, let's do first the value of Δn:
Δn = 2 - (2+1) = -1
Now, replacing all values in (2):
Kc = 5.51x10^5 / (0.082*298)^-1
Kc = 1.346x10^7
The third option is the correct one.
Answer:
True
Explanation:
Sound waves traveling through air are indeed longitudinal waves with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air do not vibrate in a transverse manner.
2.3 dL = .23 liters. d=deci=10^-1 so you move the decimal place back once.
It's D because micro is 10^-6 (move the decimal place back 6 times) 230,000x10^-6=.23 liters or 2.3 dL.
Place a 2 in front of the HCl.
This is because the product is yielded to be both H2 and Cl2, diatomic elements. In the reactants side, HCl has no coefficient, but by adding 2, the equation will become balanced.
Hope this helps!
