Competition between two species occurs when

1. Mold grows on a tree that has fallen in the forest

2. Chipmunks and squirrels eat sunflower seeds in a garden

3. A crow feeds on the remains of a rabbit killed on the road

4. A lion stalks, kills, and eats an antelope

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)

Which scenario is most similar to the type of collision that gas particles have according to kinetic molecular theory

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?
