(a)
Interpretation: The given set of chemical equations to be determined as a combination reaction, a decomposition reaction or a combustion reaction.
Concept Introduction:
A
Combination reaction is a reaction in which a single product is formed from two or more reactants.
Decomposition reaction is a reaction in which two or more products are obtained from a single reactant. Decomposition reaction is essentially opposite of combination reaction.
Combustion reaction is a reaction in which burning of substance takes place in presence of oxygen. Oxygen is supplied in excess even though the chemical equation for the combustion reaction is balanced. When compound containing carbon, hydrogen and oxygen atom is burnt in presence of oxygen, carbon dioxide and water is obtained as product.
To determine: The given set of reactions as a combination reaction, a decomposition reaction or a combustion reaction.
(b)
Interpretation: The given set of chemical equations to be determined as a combination reaction, a decomposition reaction or a combustion reaction.
Concept Introduction:
A chemical reaction is a process where one or more substances called reactants are converted to one or more different substances called products. The substances considered can either be element or compound.

- Consider the following Figure 2 and two atoms that are initially an infinite distance apart, x =00, at which point the potential energy of the system is U = 0. If they are brought together to x = x, the potential energy is related to the total force P by dU dx = P Given this, qualitatively sketch the variation of U with x. What happens at x=x? What is the significance of x = x, in terms of the potential energy? 0 P, Force 19 Attraction Total Repulsion x, Distance Figure 2. Variation with distance of the attractive, repulsive, and total forces between atoms. The slope dP/dx at the equilibrium spacing xe is proportional to the elastic modulus E; the stress σb, corresponding to the peak in total force, is the theoretical cohesive strength.arrow_forwardDenote the dipole for the indicated bonds in the following molecules.
