HELPP PLEASE could someone please show a visual representation of 2 C8H18 + 25 O2 → 16 CO2 + 18 H2O involved in a reaction

Which of these statements explains the difference between nuclear binding energy and the strong nuclear force ?

What is the molar mass of ca(cio4)2

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
