Answer:
The method which is used to separate a mixture of oil and vinegar is separation by density. Density is defined as the ratio of mass to the amount of matter i.e. volume.
Explanation:
The answer:
according to Boyle's law concerning Pressure (P), Volume (V), Temperature (T) and number of mole (n) , we have the famous formula:
PiVi = Pf Vf,
Pi=1.9kPa
Vi= 4L
Vf = 12L
T=25
n=3
Pf = ?
let's find the value of Pf
from the equation
PiVi = Pf Vf we can have Pf= PiVi / Vf
Pf = 1.9*4 / 12 = 0.63
so the answer is <span>B. 0.63 kPa</span>
Answer:
Chemical equation for photosynthesis
A water + carbon dioxide + sunlight → oxygen + glucose. B carbon + oxygen → carbon dioxide. C hydrogen + oxygen → water.
Explanation: This same photosynthesis cycle is usually expressed as: 6CO2 + 6H2O + 6O2 + C6H12O6. This implies that the solute, six carbon dioxide molecules plus 6 hydroxyl groups, are translated into something like a sugar molecule or six oxygen molecules, the goods, exploiting light energy absorbed the chlorophyll (implied by arrow).
