First shell hold 2. second shell can hold up to 8. so it should be 8.
Answer:
A precipitate will be produced
Explanation:
The Ksp of AgBr is:
AgBr(s) → Ag⁺ + Br⁻
5.0x10⁻¹³ = [Ag⁺] Br⁻]
<em>Where [] are the concentrations in equilibrium of each ion.</em>
<em />
And if Q is:
Q = [Ag⁺] Br⁻]
<em>Where the concentrations are actual concentrations of each ion</em>
<em />
We can say:
IF Q >= Ksp, a precipitate will be produced
IF Q < Ksp, no precipitate will be produced.
the molar concentrations are:
[AgNO₃] = [Ag⁺] = 0.002M * (50mL / 100mL) = 0.001M
<em>Because 50mL is the volume of the AgNO₃ solution and 100mL the volume of the mixture of both solutions.</em>
[NaBr] = [Br⁻] = 0.002M * (50mL / 100mL) = 0.001M
Q = [0.001M] * [0.001M]
Q = 1x10⁻⁶
As Q > Ksp,
<h3>A precipitate will be produced</h3>
Empirical formula would be CH3O2. This is the multiple that can be multiplied by any number to get a molecule.
The combustion of the fatty acid called stearic acid has the the complete equation; C18H36O2(s) + 26O2(g) ------> 18CO2 (g) + 18 H2O(g)
<h3>What is combustion?</h3>
The term combustion has to do with the burning of a substance in air. For organic compounds, we get carbon dioxide and water as the products.
Thus, for the combustion of the fatty acid called stearic acid, the complete equation is; C18H36O2(s) + 26O2(g) ------> 18CO2 (g) + 18 H2O(g)
