What does the octet rule have to deal with covalent bonds

1 answer:

6 0

<span>Rule of the octet is used in chemistry to indicate the tendencies of the atoms when they complete the energy level to obtain stability. Covalent bonds are what occurs when two atoms join and reach the stable octet. They are related because through this union electrons are shared and the covalent bond is produced and the rule of the octet is given to show the tendency of this union.</span>

In the reaction FeCl2 + 2NaOH ->Fe(OH)2(s) + 2NaCl, if 6 moles of FeCl2 are added to 6 moles of Na0H, how many moles of NaOH

pogonyaev

Answer : The correct option is, (B) 6 mole

Explanation :

Given moles of $FeCl_2$ = 6 moles

Given moles of $NaOH$ = 6 moles

First we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

$FeCl_2+2NaOH\rightarrow Fe(OH)_2+2NaCl$

From the given balanced reaction, we conclude that

As, 1 moles of $FeCl_2$ react with 2 moles of $NaOH$

So, 6 moles of $FeCl_2$ react with $\frac{2}{1}\times 6=12$ moles of $NaOH$

From this we conclude that, $FeCl_2$ is an excess reagent and $NaOH$ is a limiting reagent because the given moles are less than the required moles and it limits the formation of product.

Thus, the number of moles of NaOH used up in the reaction = Required moles of NaOH - Given moles of NaOH

The number of moles of NaOH used up in the reaction = 12 - 6 = 6 moles

Therefore, the number of moles of NaOH used up in the reaction will be, 60 moles

A horse gallops along a racecourse at a speed of 40 km/h. It takes the horse 3 minutes to run the length of the track.

Natali [406]

To convert minutes to hours we divide the minutes by 60. So if we divide 3 by 60 we get 0.05 hours.

<h3>How to convert minutes into hour?</h3>

We know that in hour, there are 60 minutes so if we go from minutes to hours then we have to divide the number by 60 and when we go from hours to minutes we multiply with the same 60 number.

So we can conclude that to convert minutes to hours we divide the minutes by 60. So if we divide 3 by 60 we get 0.05 hours.

What is the mass percentage of O in C₂H₄O₂? Provide an answer to two decimal places.

nasty-shy [4]

Answer:

53.29%

Explanation:

The molar mass of C2H4O2 is 60.05g and the 2 O's are 32.00g

so 32.00/60.05= 0.53288925895

and that as a decimal rounded to the nearest hundredths is 53.29%
