Answer:   2) see below

                 3) 2AgCl → 2Ag + Cl₂

<u>Explanation:</u>

2)

Step 1: Crushing & Grinding   CuFeS₂(s)→  CuFeS₂(s)

Step 2: Froth Flotation           CuFeS₂(s)---->  CuFeS₂ (l)

Step 3: Roasting   2CuFeS₂(l) + 3O₂(g) → 2FeO(s) + 2CuS(s) + 2SO₂(g)

Step 4: Converting matte to blister Cu₂S(l) + O₂(g) → 2Cu(l) + SO₂(g)

Step 5: Anode Casting           Cu(l) → Cu(s)

Step 6: Electrolytic Refining   Cu(s) → Cu(s)

            Anode: Cu(s) → Cu₂ + (aq) + 2e-

                     Cathode: Cu2 + (aq) + 2e- → Cu(s)

<em>see diagram below for illustration of steps</em>

3) When silver chloride (solid) is exposed to sunlight, it decomposes into silver (solid) and chlorine (gas).

The equation is written as:  2AgCl_{(s)}\xrightarrow{\text{sunlight}}}2Ag_{(s)}+Cl_{2(g)}

How many grams of H2O will be formed when 32.0 g H2 is mixed with 84.0 g of O2 and allowed to react to form water
adell [148]

Answer:

94.57 g H2O

Explanation:

32.0 g H2

Molar Mass H2: 2.01 g/mol

84.0 g O2

Molar Mass O2: 32.00 g/mol

Molar Mass H2O: 18.02 g/mol

First balance the eqution:

2H2 + O2 = 2H2O

Find the amount of moles that both 32.0 g of H2 and 84.0 g of O2 can produce using the molar masses:

32.0 g H2 x ((1 mole H2)/ (2.015 g H2)) = 15.88 moles H2

84.0 g O2 x ((1 mole O2)/(32.00 g O2)) = 2.63 moles O2

Now you can find the amount of grams of H2O each reactant will produce:

**keep in mind of mole ratios from balanced equation**

15.88 moles H2 x ((2 moles H2O)/(2 moles H2)) x ((18.015 g H2O)/(1 mole H2O) =286.07 g H2O

2.63 moles O2 x ((2 moles H2O)/(1 mole O2)) x ((18.015 g H2O)/(1 mole H2O) = 94.76 g H2O

94.76 is the final answer because this is the limiting reactant, meaning it produces less product than the H2 so it limits the reaction from producing anymore product from the amount calculated.

Why is it harder to remove an electron from fluorine than from carbon?
tatuchka [14]
<span>The valence electrons of both fluorine and carbon are found at about the same distance from their respective nuclei but the greater positive charge of the fluorine nucleus attracts its valence electrons more strongly. </span>

A completely reversible heat pump has a COP of 1.6 and a sink temperature of 300 K. Calculate (a) the temperature of the source
sesenic [268]

Answer:

(A) 800 K (B) 2.4 KW

Explanation:

We have given the COP =1.6

The sink temperature T_L=300K

We have to find the source temperature, that is T_H

(A) We know that COP of the heat pump is given by COP=\frac{T_H}{T_H-T_L}

So 1.6=\frac{T_H}{T_H-300}

1.6T_H-480=T_H

0.6T_H=480

T_H=800K

(B) We have given the work done =1.5 KW

The rate of heat transfer is given by Q_H=COP\times W=1.6\times 1.5=2.4KW
