Balance the following Equations. 1. Al + O2 → Al2O3

2. HCl + Mg(OH)2 → MgCl2 + H2O

CaSO3 + AlPO4 →
Al2(SO3)3 + Ca3(PO4)2

4. C4H10 +O2 → CO2 + H2O

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
