5. What distinguishes the noble gases from other elements in the main group? How does this contribute to the tendency for the various elements to react
with each other?

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.)

Design techniques and materials that reduce the negative environmental impact of a structure are referred to as

The diagram below shows the different phase transitions that occur in matter. which arrow represents the transition in which dew is formed?
