Place a 2 in front of the HCl.
This is because the product is yielded to be both H2 and Cl2, diatomic elements. In the reactants side, HCl has no coefficient, but by adding 2, the equation will become balanced.
Hope this helps!
Answer: 82.0 g/mole
Explanation:
Use the units to see that if we divide 1.64 grams by 0.0200 moles, we'll get a number that is grams/mole, the definition of formula mass.
1.64/0.0200 = 82.0 g/mole (3 sig figs)
We can't tell from this alone what the molecular formula might be, but C6H10 (cyclohexene) comes close (82.1 grams/mole).
Use the periodic table to identify atom properties such as groups and electron configurations. Elements are organized by period and group, with the period corresponding to the principle energy level, and the group relating to the extent the subshells are filled.

A product is always yield as a result of a chemical reaction

Answer: B) Bones
Explanation:
Natural casts form when flowing water removes all of the original bone or tissue, leaving just an impression in sediment.
