Answer:
Explanation:
<u>1. Calculate the iniital concentration of HI(g) introduced</u>
The initial concentration of HI(g), [HI(g)], is the number of moles per liter:
- [HI(g)] = 0.316mol/1liter = 0.316M
<u>2. Build the ICE (initial, change, equilibrium) table</u>
ICE table:
2HI(g) → H₂(g) + I₂(g)
I 0.316 0 0
C - 2x +x +x
E 0.316 - 2x x x (x = 3.12×10⁻²M)
<u>3. Find the equilibrium constant, Kc</u>
H2o is an example of covalent molecule. H2O has two hydrogen atoms bonded to one oxygen atom. The two hydrogen atoms and the oxygen atom are linked together by a covalent bond.Atoms of oxygen are electronegative and attract the sharing of electrons in a covalent bond.
Answer:
The second option is correct
= Acid can dissolve many metals
Explanation:
Acid reacts with most metals to liberate hydrogen gas, during the process the metals dissolve in the acid
Answer:
number of Carbons = 2 times number of Hydrogens
Therefore, for alkene with 10 carbons, it will have 2 x 10 = 20 hydrogens.
Its chemical formula will be
C10H20
