Answer:
so like Each of the five states of matter collectively made up all the "stuff" that's in the universe- — everything that takes up space and has mass is matter,and All matter is made up of atoms and in turn made up of protons and neutrons and electrons.
Explanation: hope this helps
Answer:
c
Explanation:
Physical Weathering is process that occurs when repeated freezing and thawing breaks apart rocks
Upon a constant pressure (P), volume (V) of a gas will vary in direct proportion to changes in temperature (T). So V1/T1 = V2/T2
V2 = V1T2/T1 = (500)(300)/150
V2 = 150000/150 = 1000 mL
Answer:
rate = k [H2O] [NO]²
Explanation:
[H2] (M) [NO] (M) Rate (M/s)
Trial 1 0.35 0.30 2.835 x 10-3
Trial 2 0.35 0.60 1.134 x 10-2
Trial 3 0.70 0.60 2.268 x 10-2
Comparing Trial 1 and 2 , the rate of the reaction increases by a factor of 4 when the concentration of NO was doubled. This means that the reaction is second order with respect to NO
Comparing Trial 2 and Trial 3, the rate of reaction increased by a factor of 2 when the concentration of H2O was doubled. This means that the reaction is first order with respect to H2O
The rate law fr the reaction is given as;
rate = k [H2O] [NO]²
