1) Zn(s) + 2 HO2CCH3(l) --> Zn(O2CCH3)2 + H2(g)

There are two half reactions:
Zn -->Zn (2+) + 2e-
2e- + 2 H+ --> H2

(the acetic acid ionized to form H+ and acetate- ions)


2) It's a red-ox (reduction-oxidation) reaction. The Zn gives up 2 electrons to the 2 hydrogen atoms. In general one element loses electrons and another gains electrons. The element gaining the electrons is the oxidizer and the element losing them is the reducing agent. The oxidizer becomes reduced and the reducing agent becomes oxidized.

3) Hydrocarbons and oxygen.

Zn + 2HCl → ZnCl2 + H2 This reaction is rapid, because HCl is a strong acid and provides more reactive H+ ions. The products are zinc chloride and hydrogen gas. Zn + 2CH3COOH → Zn(CH3COO)2 + H2 This reaction is slower, because acetic acid is a weak acid. The products are zinc acetate and hydrogen gas.

So I would classify it as expeditious
Hope it helps!

How many moles of carbon dioxide gas should be produced when 10.0 g of C2H6 are combusted at STP?
Finger [1]

Answer:

                    0.665 moles of CO₂

Explanation:

                     The balance chemical equation for the combustion of Ethane is as follow:

                            2 C₂H₆ + 7 O₂ → 4 CO₂ + 6 H₂O

Step 1: <u>Calculate moles of C₂H₆ as;</u>

                              Moles  =  Mass  /  M.Mass

Putting values,

                              Moles  =  10.0 g / 30.07 g/mol

                              Moles  =  0.3325 moles

Step 2: <u>Calculate Moles of CO₂ as;</u>

According to balance chemical equation,

                    2 moles of C₂H₆ produced  =  4 moles of CO₂

So,

             0.3325 moles of C₂H₆ will produce  =  X moles of CO₂

Solving for X,

                      X  =  0.3325 mol × 4 mol ÷ 2 mol

                      X = 0.665 moles of CO₂

How many moles are in 9.25E24 formulas units of sodium acetate?
Lelu [443]

Answer:

<h2>15.37 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{9.25 \times  {10}^{24} }{6.02 \times  {10}^{23} }  \\  = 15.365448...

We have the final answer as

<h3>15.37 moles</h3>

Hope this helps you
