Answer:
The correct option is OA.
C2H4O2 + NaHCO3 - NaC2H302 + H2O + CO2
Explanation:
To solve this you have to check the number of elements in both sides of the equation.
Answer:
if you want to have answers, don't take it wrong ...but put more details !
Explanation:
Hey there !
Number of moles of solution: 4.3 moles
Volume in liters:
450.0 mL / 1000 => 0.45 L
Therefore:
Molarity = number of moles / volume of solution ( L)
Molarity = 4.3 / 0.45
=> 9.55 M
Hope that helps!
Geology is the study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them.
The chemical equation without coefficients is:
Ca + CO2 + O2 --------> Ca CO3
You can balance that equation by trial an error.
This is the chemical equation balanced:
2Ca + 2CO2 + O2 --------> 2Ca CO3
Count the atoms on each side to check the balance
Atom Left side right side
Ca 2 2
C 2 2
O 2*2 + 2 = 6 2*3 = 6
Then those are the coefficients:
a0 = 2
a1 = 2
a2 = 1
a3 = 2
