Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum. Water droplets in the air can act in a manner similar to that of a prism, separating the colors of sunlight to produce a spectrum known as a rainbow.
2 in front of H2. Technically nothing in front of O2 otherwise put a 1 then a 2 in front of H2O
2H20 + 1O2 —— > 2H2O
Answer:
There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout. The most common type of homogenous mixture is a solution, which can be a solid, liquid, or gas.
Hope this helped :)
Answer: The given question is incomplete. The complete question is:
At a certain temperature the rate of this reaction is second order in 
with a rate constant of 
. 
Suppose a vessel contains at a concentration of 0.100 M Calculate how long it takes for the concentration of to decrease to 0.0240 M. You may assume no other reaction is important. Round your answer to 2 significant digits.
Answer: It takes 0.93 seconds for the concentration to decrease to 0.0240 M.
Explanation:
Integrated rate law for second order kinetics is given by:
= initial concentration = 0.100 M
a= concentration left after time t = 0.0240 M
k = rate constant =
t = time taken for decomposition = ?
Thus it takes 0.93 seconds for the concentration to decrease to 0.0240 M.
