Fiesta28 [93]

Answer:

D. only 2 and 3

Explanation:

The Grignard compound or reagent is a highly reactive compound formed from the reaction between an ether solvent containing magnesium and a haloalkane. This compound can also be used to create a C-C bond (carbon-carbon). Based on the properties and structure of a Grignard compound, the answer is option D.

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.

Nitrogen and oxygen form an extensive series of oxides with the general formula NxOy. One of them is a blue solid that comes apa
Marizza181 [45]

Work out the number of moles in

100.00 grams of the oxide.

For nitrogen: The atomic mass of N is 14.0067, and we have 36.84 g N:

36.84 g N14.0067 g N/mol N=2.630 mol N

For oxygen: The atomic mass of O is

15.9994, and we have

100.00−36.84=63.16 g O:

63.16 g N 15.9994 g N/mol N=3.948 mol N

Now the ratio 3.958 2.630 is very close to

1.5=32

. So we conclude that the gas has three moles

O to two moles N making the empirical formula

N2O3.
