A motorcycle starts at rest and accelerates at 7 m/s2 for 2 seconds (Δt = 2). After 2 seconds, what is the motorcycle’s velocity in meters per second (m/s)?

Given the following at 25c calculate delta hf for hcn (g) at 25c. 2nh3 (g) +3o2 (g) + 2ch4 (g) > 2hcn (g) + 6h2o (g) delta h rxn= -870.8 kj. delta hf=-80.3 kj/mol for nh3 (g), -74.6 kj/mol for ch4, and -241.8 kj/mol for h2o (g)

What are the similarities between compounds and mixtures?
