Answer: Geologists map out <em>data </em>from previous earth quakes to determine earthquakes risk.
Explanation:
Geology is the study of earth. Also, it is the study of how Earth's materials, structures etc are changed over time.
Geologist is a scientist who studies the structure of earth, rocks, soil, fossils and earthquake. So, they map out the data from previous earthquakes to determine earthquake risk.
Answer:
<em>erosion, physical reactions, chemical reactions, and gravity</em>
Hope this helps you out, dear. Have a beautiful day!!
Answer:
Chloromethane experiences dipole-dipole interactions.
Chloromethane has a higher molar mass than hydrogen.
Explanation:
The molar mass is directly proportional to the heat of fusion, since the heavier the molecules the more energy they need to separate. Intermolecular forces are also directly proportional to the heat of fusion, because the greater the interaction they experience, the more energy they require to separate. The dipole-dipole interactions experienced by chloromethane are stronger than the interactions that take place in hydrogen.
Answer:
its two valence electrons
Explanation:
Calcium is a group 2 element with two valence electrons. Therefore, it is very reactive and gives up electrons in chemical reactions.
UR WELCOME!! :)
