Does the burning of coal produce flame as the burning of wood does​

Chemistry
1 answer:
Sav [38]4 years ago
6 0

Answer:

Yes they do have the same flame

Explanation:

Wood, coal and other solid fuels burn with a flame initially because in the beginning there is ample amount of fuel to undergo a fairly efficient combustion reaction there. As more fuel gets burned, there is not much fuel left for an efficient combustion reaction to take place.

Construct the molecular orbital diagram for h2- and then identify the bond order
Sav [38]
Since 1s<span> shell of bonding orbital can accommodate only two electrons. So, next one electron will go into 1</span>s<span> shell of anti-bonding orbital.

- Bond order = (Bonding electrons - antibonding electrons) / 2
                    = (2 - 1) / 2 = 0.5

An unknown element is a mixture of
seropon [69]

Answer:

10.13086%

Explanation:

129y + 132(1-y) = 129.91

129y + 132 - 132y = 129.91

-3y = -2.09

y = 0.69666 (5 s.f.)

% abundance of 132X = 100% - (129×0.69666)%

                                    = 100% - 89.86914%

                                    = 10.13086%

                                    = 10.1% (3 significant figures)

*y is just a variable for the equation
