Part 1: Describe the mass and surface temperature of the main sequence stars.

Part 2: Explain using complete sentences where on the HR diagram you would expect to find a main sequence star based on its physical properties.

How did planetesmals form planets? a. they broke apart into smaller chunks. b. they collided and stuck together. c. they cooled and pulled ice together. d. they began to rotate.

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall.
