Answer:
C.) 0.7967
Explanation:
Hello,
Normal distribution is used here as:
In this case, the sample's pH is 8.47, the average pH 8.5, standard deviation 0.22 and sample size 37, thus:
Now, based on the table for standard normal distribution which comes from a symmetric bell-like graph, the probability is 0.797 which matched with the C answer.
Best regards.
The answer is C, good luck mate
Answer is: electronegativity decreases with increase of atomic radius, because of increased distance between the valence electrons and nucleus, so atoms tends to lose electrons easier.
Electronegativity<span> is a chemical property that describes the
tendency of an atom to attract
a shared pair of electrons towards
itself.</span>
The atomic radius of
a chemical element is a measure of the size of its atom.The atomic radius
varies with increasing atomic number, but usually increases because of
increasing of number of electrons.The atomic radius decreases across the
periods because an increasing number of protons, because greater attraction
between the protons and electrons.
Answer:
Li
Explanation:
it is li because when you put that mixture together it makes li so the answer is Li
