A body, upon heating, becomes red first, then yellow, and then other colors. Why?
A - Red light has the lowest frequency
B - Yellow light has the lowest frequency
C - Red light has the highest frequency
D - None of the above

A

Explanation:

The color red has the lowest frequency. Colors are made up of waves of light, and red has a very low frequency, which is how fast the lights move.

the answer would be c

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
