Answer:
260K
Explanation:
We use the general gas equation to solve this. The mathematical form can be represented as follows:
P1V1/T1 = P2V2/T2
We are to look for T2 from the question, rearranging the equation yields:
T2 = T1P2V2/P1V1
So what information do we have from the question:
T2= ?
P2 = 640mmHg
V2 = 198L
P1 = 760mmHg
T1 = 273K as they gas is at S.T.P since pressure is 760mmHg which is the standard pressure
V1 = 175L
We now substitute all these values:
T2 = (273 * 640 * 198)/(760 * 175)
T2 = 260K
Answer:
3km/h
Explanation:
Speed equal to distance /time
Answer:
D: to transport materials through the body.
Explanation:
A: to bring oxygen into the lung. is incorrect because it's respiratory system
B: to put carbon dioxide into all the blood vessels carbon dioxide is exhaled out of the body
C: to expel waste products from the body. is excretory system
An example of a general formula of an acid is
<span>HCl
This is called as hydrochloric acid or hydrogen chloride.
H represents for the atom of Hydrogen
and Cl represents for the atom of Chlorine
Since their charges are -1, and +1, it's ratio is 1:1</span>
