Mario believes he has found the reason that some things glow in the dark while others do not. what is the most important thing he will need to do before his theory will be accepted by other scientists? a. create a petition and ask everyone who believes in his theory to sign it. b. develop an on-line survey so people can vote on the accuracy of his theory. c. write a book promoting his theory. d. develop tests and experiments that can be repeated to prove his theory.

the answer is d, cuz i just did it rn on my study island and i got it right :)

It’s D. velocity test and experiment that can be repeated to prove his theory

m=9

step-by-step explanation:

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 :
