Step 1. Solve for the energy needed to heat 18 g of water from 70°C to 100 °C
(boiling point). Use specific heat of water
(4.2 J/g °C) as conversion factor.
18 g x (100-70) °C x 4.2 J/g °C =?

Calculate the mass of carbon in 97.0 g of sucrose c12h22o11

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
