Hey do you guys have any ideas for a science fair project

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.)

The rules of engagement (roe) working group is often used to (select all that apply.)

The chart shows the bid provided by four contractors to complete a job. which contractor is the most cost-effective?
