The statement "<span>All gaseous mixtures are solutions." is true. This is because there are a number of gaseous molecules present in a volume of gas and they are considered solutions.</span>
Some bad people will tend to forge dollar bills and make fake bills, giving them to cashiers and asking for it to be split into a different amount of bills so they are given real cash and wont be caught or they will buy things, return them and be given back real money and get away with it. This is obviously a crime because it's fake.
Answer:
7800 cells
Explanation:
The number of Escherichia coli cells N after n generations is given by
N = 2ⁿ × N₀ where N₀ = initial population
Now making N₀ subject of the formula, we have
N₀ = N/2ⁿ
Since n = 8 and N = 1,996,800 cells, substituting the values of the variables into the equation, we have
N₀ = N/2ⁿ
N₀ = 1,996,800 cells/2⁸
N₀ = 1,996,800 cells/256
N₀ = 7800 cells
So, the initial population of Escherichia coli cells is 7800 cells.
Answer:
the principal energy level of an electron refers to the shell or orbital in which the electron is located relative to the atoms nucleus. the first element in a period of the periodic table introduces a new principal energy level.
Explanation:
the electrons surrounding an atom are located in region around the nucleus called "energy level".
