First, you measured the mass of the metal and the water inside the calorimeter. ▪ Then, you the metal and added it to water in the calorimeter. ▪ After heat transferred from the metal to the water, you measured the of both materials.

first you measured the MASS of the metal and the water inside the calorimeter.

then you HEATED the metal and added it to the water in the calorimeter.

After heat transferred from the metal to the water, you measured the TEMPERATURE CHANGE of both materials

Explanation:

precipitation

explanation:

when it goes from cloud to rain/back to earth in the form of rain

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
