Because someone was wearing it and their dna could be in it i’m guessing
Answer:
Given the reaction NH3 + O2 = NO + H2O, 3.25 g of NH3 is allowed to react with 3.50 g of O2. Which reactant is the limiting reagent? How many grams of H2O are formed? How much of the excess reactant remains after the reaction?
<em>Different fluids have different boiling points depending on the bonding between the particles and the mass of the particles. The heavier the particles, the stronger the bonding, the higher the boiling point will be.</em>

Answer: Activation energy = 10 kJ
enthalpy change = -25 kJ
Explanation:
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
Given : Potential energy of the reactants = 30 kJ
Potential energy of the products = 5 kJ
Maximum energy of the system = 40 kJ.
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
Activation energy = Maximum energy of the system - Potential energy of the reactants = (40-30) kJ =10 kJ
Enthalpy change = Potential energy of the products - Potential energy of the reactants =(5-30) kJ= -25 kJ
