Answer:
Reaction is already balanced
Explanation:
The equation in reaction 1 is given as;
CH3COOH + NaHCO3 --> CO2 + H2O + Na+ + CH3COO-
The reaction is already balanced. This is because the umber of atoms of elements in the reactant is equal to that of the products
Carbon
Reactant = 2 + 1 = 3
Product = 2 + 2 = 3
Hydrogen
Reactant = 3 + 1 + 1 = 5
Product = 2 + 3 = 5
Oxygen
Reactant = 2 + 3 = 5
Product = 2 +1 + 2 = 5
Sodium
Reactant = 1
Product = 1

ANSWER IS B
Answer:
The second one is the answer
Answer:
.0924 moles of NaCl
Explanation:
So you know you have 5.4 g of NaCl and you need to know how many moles there are in this amount of NaCl
- You'll need to find the atomic mass of the compound NaCl to help you solve for moles
- Sodium (Na) on the periodic table has a mass of 22.99
- Chlorine (Cl) on the periodic table has a mass of 35.45
Add these two together----> 22.99 + 35.45 = 58.44
Now you can calculate for moles
<u>Written-out method:</u>
<u>5.4 grams of NaCl | 1 mole of NaCl </u>
| 58.44 grams NaCl = .0924 moles of NaCl
<u>Plug into calculator method:</u>
(5.4 g of NaCl/ 58.44g NaCl= .0925 moles)
