A pure compound contains many elements.
(10)an object will continue to travel at a constant speed unless acted by an unbalanced force according to newtons second law every force acted on a body has a equal and opposite reaction so the speed and the direction of the object will change.
(9) balanced force (i think so )
hope this is what you needed the 10th one is for understanding you can shorten it after reading and i think what i have written is not wrong :P:P:P;p:P:):):):D=) for the ninth one i am not sure but i think so :P:)=)
Answer:
states that rock layers with the same unique groupings of fossils are of the same geologic age.
Explanation:
The principle of fossil correlation states that the presence of similar fossils of dead organisms in rock layers indicates that the organisms under investigation must have existed around the same geologic time. This principle can be used in dating the periods when the organism being studied lived.
The geological age system follows a chronological format in tracking the age of an item under study by grouping the time periods that organisms lived into strata.
Answer: It takes 5.89 s for the concentration of 
to decrease by 88.0%.
Explanation:
As the units of rate constant is 
, the kinetics must be second order.
Integrated rate law for second order kinetics is given by:
= initiaal concentration = 0.590 M
a= concentration left after time t = 
Thus it takes 5.89 seconds for the concentration of to decrease by 88.0%.
Chromatin is composed of both DNA and other proteins in which the Double stranded molecule of DNA wraps around. The answer is B.
