A chemical equation is composed of chemical formulas. It has reactants on the left and products on the right side of an arrow symbol (→). The arrow is usually read out as ‘yields’. In an equation, all chemical formulae on one side are separated by a plus sign. The physical state...
FINAL STEP To complete your chemical equation add states of matter 2C2H6 (g)+ 7O2 (g)→ 4CO2 (g) + 6H2O (g) (g) = gas (aq) = aqueous (l) = liquid (s) = solid

Now, a more accurate way of identifying “Absolute Salinity” has been devised and incorporated into a Thermodynamic Equation of Seawater. unesdoc.unesco.org 现在, 一种更加精确的确定“绝对盐度”的方法已经设计出来,并用于海水 热力学方程中。 unesdoc.unesco.org [...] used for ad hoc strategic ai...
A balanced chemical equation expresses the relative number of moles of each component (product or reactant), but because each formula in the equation implies a definite mass of the substance (its molar mass), the equation also implies that certain weight relations exist between the components. Fo...
