Answer:
0.625 kg
Explanation:
Since 90.6 is 3 half-lives from 30.2 (90.6/30.2 = 3) , divide the initial mass of the sample by 2, and divide that quotient by 2, and divide THAT quotient by 2 to determine how much remains after 3 half-lives.
Answer:
950mL
Explanation:
The following were Data were obtained from the question:
Initial volume (V1) = 100mL
Initial pressure (P1) = stp = 760mmHg
Final pressure (P2) = 80mmHg
Final volume (V2) =..?
The final volume of the gas can be obtained by using the Boyle's law equation as follow:
P1V1 = P2V2
760 x 100 = 80 x V2
Divide both side by 80
V2 = (760 x 100) /80
V2 = 950mL
Therefore, the new volume of the gas is 950mL
Answer:
Japanese is educated place so they invent those things which are really good and helpful...
in my opinion it is safe....
The answer would be: <span>a.a mixture that is uniform throughout
A homogenous mixture would be hardly distinguishable since the solute spread evenly inside the solvent. A heterogeneous mixture is not spread evenly so it is </span>easily distinguishable.A suspension has a big molecule solute that will slowly settle and make sediment at the base of the solution. A colloid mixture is suspended but it won't settle like suspension does.
Answer:
Liquid
Explanation:
My reason is that liquid takes the shape of any container and can also be expand by boiling to change it volume also be compressed by freezing or less than it room temperature
