When H2SO4 is added to PbI2, a precipitate of PbSO4 forms. The PbSO4 is then filtered from the solution, dried, and weighed. If

Answer:

$n_{I^-}=3.11x10^{-4}molI^-$

Explanation:

Hello,

In this case, the undergoing chemical reaction is shown below:

$H_2SO_4(aq)+PbI_2(aq)\rightarrow PbSO_4(s)+2HI(aq)$

Thus, we obtain 0.0471 g of lead (II) sulfate, the iodide ions in the original solution are computed below by stoichiometry, taking into account that into 1 mole of lead (II) iodide there are 2 moles of iodide ions:

$n_{I^-}=0.0471gPbSO_4*\frac{1molPbSO_4}{303.26gPbSO_4}*\frac{1molPbI_2}{1molPbSO_4}*\frac{2molI^-}{1molPbI_2} \\n_{I^-}=3.11x10^{-4}molI^-$

Best regards.

What chromosomes move to the middle of the spindle during what phase

Contact [7]

This happens during metaphase. I remember this phase because it is the move phase
of mitosis. The m from move matches the m from metaphase.

As a result of the transfer of an electron from a less electronegative atom to a more electronegative atom,

Viktor [21]

<u>Answer:</u> The correct answer is Option d.

<u>Explanation:</u>

Electronegativity is defined as the tendency of an element to attract the shared pair of electron towards itself in a compound.

When electron is transferred from less electronegative atom to more electronegative atom.

The atom which is more electronegative gains electron and undergoes reduction reaction.

Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

During the transfer of electrons, energy is released when an electron looses is potential energy during the transfer.

Hence, the correct answer is Option d.

What is the concentration, in m/v percent, of a solution prepared from 50 g NaCl and 2.5 L of solution?

Serjik [45]

When we convert the given mass in grams and volume in liters to m/v percent, we recall that m/v percent is expressed as grams/100 milliliters. In this case the expression becomes (50 grams/ 2500 L)*(0.1L/100ml), that is equal to 0.002 grams/ 100 mL. Hence the the concentration is equal to 0.2 m/v percent.
