Acertain chemical reaction experiences a 7.50 x 10-7 kilogram loss in mass. if this mass were to be totally converted to energy, what would be the magnitude of that energy? (1 j = 1 kg m2/s2)
1.20 x 1023 j
2.5 x 109 j
4.00 x 101 j
6.75 x 1010 j

58 km per hour : d

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

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 :
