Charlie is balancing an equation. she has identified the atoms and counted the number of each in the reactants and products.
what would charlie adjust to make the number of atoms in the reactants the same as the number of atoms in the products?
coefficients
subscripts
superscripts
parentheses

Answer:

Charlie adjust the coefficients to make the number of atoms in the reactants the same as the number of atoms in the

Explanation:

Stoichiometric coefficients are the number that appears before the symbol in each compound or element in the equation of a chemical reaction. By rule, it is positive for products and negative for reactants. Stoichiometric coefficients help in describing the stoichiometry of a chemical reaction.

According to "law of conservation of mass" that states "total reactant's mass equals the overall mass of obatined from the product". Thus, Charlie would adjust coefficients to equalise the number of atom in reactants and products.

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 :
