The reaction 3no ® n2o + no2 is found to obey the rate law rate = k[no]2. If the first half-life of the reaction is found to be 4. 6 s, what is the length of the fourth half-life?.

Layer r contains a well-known index fossil that is 100 million years old. based on this information and the principle of superposition, a. layers t and m are older than 100 million years, and layers x and g are younger than 100 million years. b. layers t, m, x, and g are all older than 100 million years. c. layers t and m are younger than 100 million years, and layers x and g are older than 100 million years.
