Acertain reaction has this form: aa    bb. at a particular temperature and [a]0  = 2.00 x 10-2  molar, concentration versus time data were collected for this reaction and a plot of ln[a]t  versus time resulted in a straight line with a slope value of -2.97 x 10-2  min-1.  what is the reaction order and rate law for this reaction? a.  first, rate = k[a]b.  first, rate = k[a]2c.  second, rate = k[a]d.  second, rate = k[a]2e.  third, rate = k[a]

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

1.solid

2.carbon dioxide

3.helium

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
