Using what you know about the kinetic energy equation, which object would have the greater kinetic energy? Explain why in your response. A: A mouse running 3 m/s
B: An elephant running 3 m/s

kinetic energy = ½ (mass) (velocity)2

The elephant

Explanation:

Things with more mass tend to have more kinetic energy. Since they are going at the same speed, the elephant boasts greater mass than the mouse giving it more kinetic energy.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

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 :
