What is the change in heat (NOT change in temperature) for a 35.0 g sample of aluminum that cools from 70.0°C to 25.0°C if aluminum has a specific heat capacity of 0.900 J/g°C? (answer is in joules with 2-3 sig figs) (MAKE SURE you check the sign of your answer, is the aluminum gaining or losing heat?)

i will, dm me on here.

explanation:

i need some with some bio stuff see if anyone will

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
