Answer:

Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.

Explanation:

Erosion can be defined as a geological process which involves the wearing away of earth material and transportation of these material to another location by Natural agents such as wind and water. Erosion involves removal of top soil, rocks and other earth particles by action of wind, glacier and water.

Wind causes erosion by deflation. Deflation is the actual removal of grain of rocks . Generally, it s the lowering of land surface that happens as a result of removal of surface particles(sands grains) by wind. Deflation is usually prevalent in arid areas. This sand can later be picked up and deposited to form sand dunes . Sand dunes are mounds of sand formed by wind . This sands are sheltered by an obstacle. And sand dunes are prevalent in desert and or along the beach. The sand dune grows as sand accumulate.

I am using all my points to ask this. please help

ELEN [110]

Answer:

C5H7N

C10H14N2

Explanation:

ok so lets lay out this nicely

elements C H N

percentage 74 8.7 17.3

mass number 12 1 14

divided percentage by mass 6.167 8.7 1.2357

now divide the smallest number with the 4.99 7.04 1

rest for instance 1,237 is the smallest.

so 6.167÷1,237

and 8.7 ÷1.237

and 1,237 divide 1.237

now the ratio is C5H7N

now for molecular formula find Mr of C5H7N which is (12×5)+7+14=81

next divide 162.1÷81=2

so now for molecular formula just multipily everythng by 2

How many significant figures are in the measurement, 0.005890 g?

pantera1 [17]

4 significant figures. Use a rule called the Atlantic-Pacific rule where if the period is absent (Atlantic), you would start counting the numbers from right to left. If the period is present (Pacific), then start counting the numbers from left to right. Since the period is present, start from 5 and there are 4 digits including 5.
