Explanation:
Step 1
Phosphoric Acid is a triprotic acid where H3PO4 dissociates to H2PO4- which then further dissociates HPO42- and it then forms PO43-. Equation for acid dissociation constant for the dissociation of H3PO4 and HPO42- can be written as above.
Step 2
Concentration of H2PO4- produces during the dissociation of H3PO4 can be determined by constructing an ICE table.
Step 3
Concentration of HPO42- produces during the dissociation of H2PO4- can be determined
The chemical reaction for this is:
2 C2H6 + 7 O2 => 4 CO2 + 6 H2O
Solving for CO2 with each reactant will give:
21.0 g C2H6 x (1 mol C2H6/30.08 g C2H6) x (6 mol H2O/2
mol C2H6) x (18 g H2O/1 mol H2O) = 37.70 g H2O
110 g O2 x (1 mol O2/32.00 g O2) x (6 mol CO2/7 mol O2) x
(18 g H2O/1 mol H2O) = 53.04 g H2O
Since the amount of H2O in C2H6 is lower therefore C2H6
is the limiting reactant and the maximum amount of water is only 38 g H2O (2 significant digits)
ANswer:
38 g water

Sorry, thatis the most i can do
Answer:
1
Explanation:
outershell atoms of an element are also known as valency of that element
so the valency and number of elctron in the outershell of a sodium atom is +1.
hope this will help
mark me as brilliant
Answer:
No
Explanation:
Atomic number represents the identity of atoms
using number of protons which is equal in isotopes.
