Answer:
Moles of zinc chloride produced are 0.09942 moles.
Explanation:
Mass of zinc used = 6.5 g
Moles of zinc =
According to reaction, 1 mol of zinc gives 1 mole of zinc chloride,then 0.09942 moles of zinc will give :
of zinc chloride
Moles of zinc chloride produced are 0.09942 moles.

THANKS SO MUCH
I actually did the same thin last week
Explanation:
F - Fluorine
Explanation:
Fluorine is the atom that is most able to attract electrons to itself among the choices. The ability of an atom to attract electron to itself is called electronegativity.
- Electronegativity is a measure of the relative tendency with which atoms of an element attracts valence electrons in a chemical bond.
- Fluorine is the most electronegative element on the periodic table.
- According to Pauling's table on electronegativities of elements, it has a value of 4.0.
- This is the highest on the periodic table of elements.

Answer:
Taking the animal kingdom as an example, we can see that it is split into two clear groups: Invertebrates - animals without a backbone. Vertebrates - animals with a backbone.
Explanation:
Answer:
The mole is simply a very large number that is used by chemists as a unit of measurement.
Explanation:
The mole is thus the link between the micro world of atoms and molecules, and the macro world of grams and litres, the which we can easily measure by mass or volume. The masses for a mole of each element are given on the periodic table as the atomic weight. So, if have 12 g of
C
, I know, fairly precisely, how many atoms of carbon I have. Given this quantity, I know how many molecules of O
2 are required to react with the C
, which I could measure by mass or by volume.
