Avogadro's Law states that the volume of any gas is proportional to the number of mole molecules of the gas. Calling, n the number of moles of molecules of the gas, the proportionality equation is: V is proportional to n => V = K*n. The proportionality constant depends on the temperature and pressure. K = (RT / P) => V = (RT/P) * n, So, Avogadro's law states that <span>at constant pressure and temperature, the volume of a gas is directly proportional to the number of moles of molecules of the gas.</span>

<span>The choices are as follows:
h2o + 2o2 = h2o2
 fe2o3 + 3h2 = 2fe + 3h2o

caco3 = </span><span>cao + co2

The correct answers would be the second and the last option. The equations that are correctly balanced are:

</span> fe2o3 + 3h2 = 2fe + 3h2o 
caco3 = cao + co2

To balance, it should be that the number of atoms of each element in the reactant and the product side is equal.

What is the kb of the base po−34 given that a 0. 48m solution of the base has a ph of 12. 70? the equation described by the kb v
podryga [215]

The equation described by the kb value is 5.21 x 10^-^3.

The potential of Hydrogen is what pH is formally known as. The negative logarithm of the concentration of H+ ions is known as pH. Thus, the definition of pH as the amount of hydrogen is provided. The hydrogen ion concentration in a solution is described by the pH scale, which also serves as a gauge for the solution's acidity or basicity.

Assuming  PO₄³⁻ (the phosphate anion).

PO₄³- + H₂O ==> HPO₄²⁻ + OH⁻

Kb = [HPO₄²⁻][OH⁻] / [PO₄³⁻]

We can find the [OH⁻] from the pH of 12.70.

pH + pOH = 14

14.0 - 12.7 = 1.3 = pOH

[OH] = 1x10^-^1^.^3

[OH-] = 5.0x10^-^2 M

[HPO₄²⁻] = 5.0x10^-^2 M

Kb = (5.0x10^-^2)2 / 0.48

     = 2.5x10^-^3 / 0.48

Kb = 5.21 x 10^-^3

Why is it important to calibrate your pipet before beginning an experiment?
den301095 [7]

Answer:

To ensure provide and reliable data

Explanation:

Calibration ensures precise repeatable performance while preventing pipetting errors. Just the way measurement standards are established to distinguish valid and invalid processes, pipette calibration standards are designed to ensure the best pipette accuracy.
