Why is a bunsen burner flame hotter than a normal gas flame

Chemistry
1 answer:
MariettaO [177]3 years ago
7 0
While the normal gas flame can only produce a “operating” to “light blue” type of flame, the Bunsen burner can at least yield three types of flame. Consequently, the following: <span><span />

Operating flame
– which is yellow/orange in color, near 300° C. </span> <span><span>·     </span>

Blue flame – can be imperceptible under normal lighting conditions, near 500° C. The typically used laboratory type of flame.</span> <span><span>·    

</span>Roaring-blue flame – forms a triangular shaped in the center of the flame normally light blue in color and interestingly, it’s a sound-producing flame. Heat is near to 700° C. </span>

Imagine with this three kinds of flame produced and a Bunsen burner creates compared to a simple normal gas flame. In sense, the roaring-blue flame proves evident as to why Bunsen burner is hotter hence, the amount of heat it makes (700°C) it makes.

Consider the following elementary reaction:
Marat540 [252]

Answer:

[NO]=\frac{k_{-1}}{k_1} [N_2O_2]

Explanation:

Hello!

In this case, since the reaction may be assumed in chemical equilibrium, we can write up the rate law as shown below:

r=-k_1[NO]+k_{-1}[N_2O_2]

However, since the rate of reaction at equilibrium is zero, due to the fact that the concentrations remains the same, we can write:

0=-k_1[NO]+k_{-1}[N_2O_2]

Which can be also written as:

k_1[NO]=k_{-1}[N_2O_2]

Then, we solve for the concentration of NO to obtain:

[NO]=\frac{k_{-1}}{k_1} [N_2O_2]

Best regards!

One gram of Sn was electroplated from a SnCl, solution in 30 minutes. What was the current used?
Andrews [41]

Answer:

0.903 A

Explanation:

We have given mass of Sn = 1 gram

Time t=30 minutes=30×60=1800 sec

According to Faraday law m=zit

Where z is electron chemical equivalent

z is calculated by z=\frac{atomic\ mass}{nF} where n is number of element and F is Faraday constant

So z=\frac{atomic\ mass}{nF}=\frac{118.71}{2\times 96500}=0.000615

So 1=0.000615\times i\times 1800

i =0.903 A
