Select the correct answer. A certain reaction has this form:aA - BB.
At a particular temperature and [A], = 2.00 x 10-2 Molar, concentration versus time data were collected for this reaction and a plot of In[A]t
versus time resulted in a straight line with a slope value of -2.97 x 10-2 min. What is the reaction order and rate law for this reaction?
OA. first, rate = K[A]
OB
first, rate = k[A]2
OC. Second, rate = K[A)
OD
second, rate = k[A]2
O E. third, rate = K[A]

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

answersilicon (si); oxygen (o);

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
