The function of mordant in the gram staining is to expose grams positive cell to the decolorizer which dissolves the lipids in the cell wall thus allowing the crystals violent-iodine to leach out of the cell. This facilitate the cell subsequently be stained by with safranin.
Even in pitchblende, polonium is exceedingly rare: 1,000 tons of ore must be treated to yield 40 milligrams of polonium. It has a one-part-in-ten-thousandth-thousandth-thousandth-thousandth-thousandth-thousandth It is found in nature as a byproduct of the radioactive decay of uranium, thorium, and actinium.
Atomic Number: 210
To be able to calculate the number of moles for this problem, for simplicity, we assume that it is an ideal gas. We use the equation PV = nRT. We do as follows:
PV = nRT
n = PV / RT
n = 1(100000) / 0.08206 (27 + 273.15)
n = 4060.04 mol
Answer:
V₂= 33581.4 ft³
Explanation:
Given data:
Initial temperature = -15 °C (-15+273 = 258 k)
Initial volume = 28500 ft³
Final temperature = 31 °C (31+273 = 304)
Final volume = ?
Solution:
According to the Charles's law
Temperature and volume are directly related to each other.
V₁/T₁ = V₂/T₂
V₂ = V₁×T₂ /T₁
V₂ = 28500 ft³ × 304 k / 258 k
V₂ = 8664000 ft³.k/ 258 k
V₂= 33581.4 ft³
