What's the answer? It asked to be 20 characters long so just writing this.
Light acts as a wave so when you burn a certain element it generates a specific wavelength which represents a specific color light. ^-^
Answer:
The concentration after 20 mins is 0.832 M
Explanation:
Zero order rate law is given by;
R = K [A₀]⁰
A zero order reaction, rate is independent of the initial concentration
R = K
Where;
R is the rate of reaction
K is the rate constant = 0.0416 M/min
Since R = K,
Then, R = 0.0416 M/min
After 20 min, the concentration will be;
A = Rt
A = (0.0416 M/min)(20 min)
A = 0.832 M
Therefore, the concentration after 20 mins is 0.832 M
Answer:If a bouncing ball has a total energy of 20 J and a kinetic energy of 5 J, the ball’s potential energy is 15J.
If the kinetic energy of the ball decreases, then the potential energy will Increase.
Explanation:
Answer:
A.0.20M
Explanation:
c 1 V 1 = c 2 V 2
Initial Volume, V1 = 200 mL
Final Volume, V2 = 200 + 400 = 600 mL
Initial Concentration, c1 = 0.60 M
Final Concentration, c2= ?
Solving for c2;
c2 = c1v1 / v2
c2 = 0.60 * 200 / 600
c2 = 0.20M
