Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.

calcium is obtained industrially by electrolysis of molten cacl2 and is used in aluminum alloys. how many coulombs are needed to

Vinvika [58]

It takes 107 minutes 22 seconds and 96500 coulombs of charge produce 20.2 g of calcium.

The balanced equation for the reaction is,

$CaCl _{2} \:→ \: Ca ^{ 2 + } + 2Cl {}^{ - }$

The half-reaction of calcium is,

$Ca ^{2 + } + 2e ^{ - } → \: Ca$

Mass of calcium = 20.2 g

The molecular mass of calcium = 40 u.

The number of moles calcium are,

$Number \: of \: moles = \frac{mass}{molecular \: mass}$

$= \frac{20.2}{40}$

$= 0.5 \: moles$

One mole of Calcium is produced by 2 moles of electrons.

So, 0.5 moles of Calcium produce,

$= 0.5 \times 2$

$= 1 \: mole \: of \: electron$

The charge required to produce 202 g of calcium is,

$= 1 \:F$

$= 1 \times 96500 \: C$

$= 96500 \: C$

Current = 15 A

The time taken to produce 20.2 g of calcium is,

$I = \frac{Q}{T}$

$T = \frac{96500}{15}$

$= 6433.3 \: s$

$= 107 \: minutes \: 22 \: seconds$

Therefore, 96500 columns of charge are required to produce 20.2 grams of calcium. And it takes 107 minutes and 22 seconds.

Olin [163]

A: incorrect because there will be no effect on keeping the rats in separate cage in the same room at the time of the experiment.

C: incorrect because it's depend upon scientist whether he wants to record the observation on the graph or on the table. Thus, no affect will be caused on the observations.

D: incorrect because peer review is done only after the experiment is completed.

Thus, statement B is correct because the growth graph of male and female of any species is different. Male tend to grow more than their female counterparts. So, for the process of the study it is essential that all the rats included are either male or female.

Hence, option (B) is correct.
