It might be more suitable because some data cannot use a graph to show data because there is too much data.
Answer:
Option E is the correct one
Explanation:
K₂Cr₂O₇ → Potassium dichromate
A ionic salt which its molar mass is 294.18 g/m
It is composed by 2 mol of K, 2 mol of Cr and 7 mol of O
2 mol of K = 78.2 g
2 mol of Cr = 104 g
7 mol of O = 112 g
In 294.2 g of compound we have __78.2 g K __ 104 g Cr ___ 112 g O
Let's calculate the percent
(78.2 / 294.2) .100 = 26.59% K
(104 / 294.2) .100 = 35.35% Cr
(112 / 294.2) . 100 = 38.06 % O
Correct Answer: <span>O and P
Reason:
The nature of bond depends on the electronegativity difference of constituent atoms. If difference in electronegativity of constituent atoms is more, it will result in ionic bonding. Alternatively, if difference in electronegativity of constituent atoms is less, it will prefer covalent bonding. Further, covalently bonded </span><span>elements are most likely to form polyatomic ions.
In present case, electronegativity difference of O and P is minimum. Hence, they </span><span>are most likely to form polyatomic ions.</span>
Answer:
the answer would be A have good day
Explanation:

A polar covalent bond is a covalent bond in
which the atoms have an unequal attraction for
electrons and so the sharing is unequal. ... The
atom with the greater electronegativity acquires
a partial negative charge, while the atom with
the lesser electronegativity acquires a partial
positive charge.
