What is the answer to this question
Answer:
<u>∆H° reaction = -890.3 kJ</u>
Explanation:
The given equation is :

Now ,
O2 is in the standard state so its ∆H° is zero.
∆H° is calculated by considering the formation of CO2 , H2O and CH4 .
..........∆H°a = -393.5 kJ
.....∆H°b = -285.8 kJ
..........∆H°c = -74.8 kJ
Multiply equation of water H2O by 2
and reverse the direction of equation of CH4
Hence the sign of ∆H°c = +74.8 kJ becomes +ve.
We are doing this because CH4 is to be in the reactant side not in the product side.
∆H° reaction = ∆H°a +2(∆H°b) -∆H°c
∆H° reaction = -393.5 - 2(285.8) + 74.8
∆H° reaction = -890.3 kJ

Answer:
A
Explanation:
This popular experiment enabled us to know the charge of an electron. It was performed by Robert Millikan and Harvey Fletcher and have the process and procedure to measure the elementary electronic charge. In fact, Robert Millikan was awarded the Nobel prize in physics in the year 1923 for how efforts.
They were able to determine the charge by repeating the experiment for several droplets and later proposed that the charges were integer multiples of a particular base value.
