## energy question

1. coal is a major source of energy for electricity, of which industry is the largest user. Anthracite coal is a high-molar-mass carbon compound with a composition of about 95% carbon by mass. A typical simplest-ratio formula for anthracite coal is C52H16O(s) the standard enthalpy of formation of anthracite can be estimated at -396.4 KJ/mol. what is the quantity of energy available from burning 100.0 kg of anthracite coal in a thermal electric power plant, according to the following equation?

$2 C_{52}H_{16}O_{(s)}+ 111 O_{2}(g) \rightarrow 104 CO_{2}(g)+16H_{2}O(g)$
