Greetings students. A chemist puts 6 moles of nitrogen and 7 moles of hydrogen into an evacuated

the question has given two chemical equation the first chemical equation is calcium carbonate so

Consider the axo -grimic reaction this. Delta X is given at 2000 Kelvin, the equilibrium constan

Here we need to find out the mass of the aspirin. Here we have C7H603 solid plus C4H603 and here

So, we have been given with the reaction that Fe2O3 solid reacts with 3 moles of H2 in the gas p
