number one: when substances like rock and minerals are being physically broken down, its called weathering.
Number two: when particles are carried away to another location exp " a river carrying rocks to an ocean" that's called deposition
Number three: this would also be weathering because it is physically being worn down
Number four: would be a topographic map, because theses maps use lines to study elevation instead of color
Ionization energy increases from left to right in the row and from bottom to top in a column. Also as we get closer to the nucleus it would be harder to take electrons out. B (atomic #5) has 2 layers of electron 2 and 3 atom in each layer. P has 15 so it would be 2,8 and 5 respectively. Ca is 20 so 2,8,8,2 and Zn is 30 and it would be 2,18,8,2.
For energy between second and third ionization we are looking at taking out the 3rd electron. B already has 3 electron in the first layer so its easy to take them all. P has 5 in the last layer so again easy. But when we look at Ca and Zn after the 2nd electron (in the last layer) we should change the layer go one layer inside. So this needs more energy. To pick between Zn and Ca (they are in the same row) I mentioned earlier that in one row as we go to the right ionization energy increases so the answer is Zn.
Answer:
A is oxidation . B is reduction
Explanation:
A will be oxidation agent because there is gain of
electrons
B will be reducing agent because there is loss of
electrons.
Less water = less weight to make it rise
More water = more weight to make it dive
