Answer:
Solubility = [SO₄²⁻]
Explanation:
Solubility of Ag₂SO₄ can be determined by its ksp equilibrium:
Ag₂SO₄(s) ⇄ SO₄²⁻ + 2Ag⁺
<em>Where 1 mole of silver sulfate dissolves producing 1 mole of sulfate ion and 2 moles of silver ion.</em>
Solubility is defined as the amount of solid that can be dissolved per liter of solution.
The moles of Ag₂SO₄ dissolved are equal to moles of SO₄²⁻.
That means:
<h3>Solubility = [SO₄²⁻]</h3>
Answer:
See the explanation.
Explanation:
Hydrocarbons on combustion give carbon dioxide and water.
Hydrocarbons contain all kinds of saturated and unsaturated ones.
Alkanes on reaction with oxygen gives carbon dioxide and water.
Alkenes on reaction with oxygen gives carbon dioxide and water.
Alkynes on reaction with oxygen gives carbon dioxide and water.
Answer:
Argon has 8 valence electrons making it non reactive.
Explanation:
Reactive chemicals are store in containers filled with Argon gas because the argon gas is non reactive. This is true because the argon gas has completely filled octet structure.
This can further be explained by writing the electronic configuration of argon.
The electronic configuration of argon is given below:
Ar (18) => 1s² 2s²2p⁶ 3s²3p⁶
Valence electron => 3s²3p⁶ = 2 + 6 = 8
From the above illustration, we can see that the outermost shell (i.e 3s²3p⁶) is having 8 electrons indicating that it is completely filled as the maximum number of electrons any shell can accommodate outside the first shell is 8 electrons. Thus, argon has 8 valence electrons ( i.e electrons in the outermost shell) and hence it is non reactive as the outermost shell is completely filled.
I'm pretty sure it's organic chemistry.
<em>mC₃H₈: 44 g/mol</em>

---------------------
C₃H₈ + 5O₂ ----> 3CO₂ + 4H₂O
44g (44·3)g
44g C₃H₈ ------ 132g CO₂
15g C₃H₈ ------ X
X = (15×132)/44
<u>X = 45g CO₂
