<span>It is a double replacement, followed by a decomposition.

NaHCO3(aq) + CH3COOH(aq) → CH3COONa(aq) + H2CO3(aq) (double replacement)
H2CO3(aq) → H2O(l) + CO2(g) (decomposition)

The decomposition is so fast that you have no measurable concentration of H2CO3 in the solution. The formation of CO2 forms the bubbles in the solution. </span>

Which statement is true about the electrons in each polar bond of a water molecule?
Greeley [361]

They are more attracted by the oxygen atom than by the hydrogen atom.

Explanation:

In the polar bond of water which is made up of hydrogen and oxygen atoms, the shared electrons are more attracted by the oxygen atom than by the hydrogen atom.  

The interatomic bond in water is a polar covalent bond.  

In this bond type, two species shares their valence electrons.  

The bond usually occurs between non-metals with an electronegativity difference that is small.

Oxygen is more electronegative compared to hydrogen.

  • This implies that oxygen pulls the electron more closely to itself since it has a greater affinity.
  • This leaves a partial negative charge on oxygen and a positive charge on hydrogen.
  • The molecule is said to be polar covalent.

2 KClO_2 produces 2 KCl+ 3O_2 when heated. If this reaction produces 82.8 g of KCl how many grams of O2 were produced?
Ad libitum [116K]

Answer:

37.046 grams of oxygen gas were produced.

Explanation:

2KClO_2\rightarrow 2KCl+ 3O_2

Moles of potassium chlorite = \frac{82.2 g}{106.5 g/mol}=0.7718 mol

According to reaction 2 moles of potassium chlorite gives 3 moles of oxygen gas.

Then 0.7718 moles of potassium chlorite will give:

\frac{3}{2}\times 0.7718 mol=1.1577 mol of oxygen gas.

Mass of 1.1577 moles of oxygen gas:

1.1577 mol × 32 g/mol = 37.046 g

37.046 grams of oxygen gas were produced.
