Of the following, which is most likely to result after a farmer sprays his crops with pesticides?D. A neighbor’s well tests positive for pesticides.
Carbon dioxide is a colorless, odorless gas. Why is it considered a pollutant?
A. It gets into natural waters and kills fish.
Answer: A. 219K
Explanation:
Using the Combined Gas Law; P1 V1/T1 = P2V2/T2
Where P1 = 0.92 atm, P2 = 1.00 atm
V1 =4.0 L, V2 = 5.0 L
T1 = ?, T2 = 25 celcius = 298K
We therefore make T1 the subject of the formular;
T1 = P1 . V1 .T2 / P2. V2
= 0.92atm x 4.0L x 298K / 1.00 atm x 5.0 L
= 1096.64 / 5
= 219.328 approx 219K
True... atoms contain what are called electrons and protons. the protons being possitively charged and the elctrons being negatively charged
speed and direction in which an object is moving. both speed and direction of motion. is a vector. two or more velocities add by velocity addition.
