One mole methane undergoes complete combustion in a stoichiometric amount of air. the reaction proceeds as ch, + 20, → co2 + 2h2o both the reactants and the products are in gas phase. ah, = - 730 kj/mol of methane. if the average specific heat of all gases and vapours is 40 j/mol k, the maximum temperature rise of the exhaust gases in k would be approximately equal to (a) 1225 (b) 1335 (c) 1525 (d) 1735

Nonmetals usually react by gaining electrons

Idon't see the pic?

Sorry i dont understand the question can you rephase it?

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
