This is stating that, if x was 2, what is the answer to the equation.
So basically, the equation is 2^2 - 2(2) = ?
The first step is 2 squared, which is 4, then you subtract 2(2) or 4. So 4-4 is 0.
The value of f(2) is 0
A would be correct.
According to Ohm's law, Voltage divided by "Current" is equal to resistance.
R = V / I
Hope this helps!
Decomposers eat dead animals, like bacteria feeding on a deer. They also support plant life by breaking down animals, which makes the soil rich in nutrients.
The value of kb of cyclohexane in the given question is; kb = 2.82 °C/m
<h3>Understanding Molality of a Solution</h3>
Molality of solution = (Number of moles of C₆H₄Cl₂)/(Mass of Cyclohexane)
Now;
Number of moles of C₆H₄Cl₂ = Mass/molar mass = 2g/147 g/mol
Number of moles of C₆H₄Cl₂ = 0.0136 mol
Molality of solution = 0.0136/(22.5 * 10⁻³ kg)
Molality of solution = 0.6 m
Now, to find kb for cyclohexane, we will use the formula;
T_b(solution) - T_b(solvent) = kb × molality of solution
Thus;
82.39 - 70 = kb * 0.6
kb = (82.39 - 70)/0.6
kb = 2.82 °C/m
