How many moles of each element are in one mole of Sr(HCO3)2?
2 answers:
Explanation:
Since it is given that the compound is one mole.
So, the elements present in it are strontium, hydrogen, carbon and oxygen.
Therefore, moles of elements present in are as follows.
Number of strontium atom is 1.
Number of hydrogen atoms are 2.
Number of carbon atoms are 2.
Number of oxygen atoms are = 6.
Thus, we can conclude that there is 1 mole of Sr element, 2 mole of H element, 2 mole of carbon atom, and 6 moles of oxygen atom.

Answer:
<em>Three (3) of the molecules are polar: </em><em> </em>
<em> </em>
<em>.</em>
Explanation:
Polar substances have their elements held together by a covalent bond that contain partially positive and negative charges, which results in a difference in the charges' electronegativity difference (usually ranging between 0.4 and 0.7).
- PCl5 is <u>non-polar</u> with a symmetric geometry
- CoS is <u>polar</u>
- XeO3 is <u>polar</u>, with a trigonal pyramidal molecular geometric
- SeBr2 is <u>polar</u> as the difference their electronegativity is about ).5
