Data:
Arsenic Molar Mass = 74,9216 ≈ 75 u (<span>atomic mass unit)</span>
Solving:
1 mole of arsenic → 75g ------------ 6,02*10²³ molecules
..................................X -------------- 1 molecule
6,02*10²³X = 75
Answer:
Higher concentration to an area of lower concentration
Explanation:
When you open a perfume bottle at a corner of a room, after a while, its fragrance can be perceived across a distance at the other end of the room. This is because, molecules of the compound in the fragrance have moved from the area of higher concentration in the perfume bottle, across a concentration gradient to a region of lower concentration at the other end of the room. This is diffusion.

Winds and ocean currents are evidence for the process of regulating and stabilizing the climate patterns.
<h3>What are winds and ocean currents?</h3>
Ocean current is the flow or movement of water in a direction by gravity, wind, and difference in density of the water.
Wind currents pull water and create ocean currents. The current flow to westwards, which is called Coriolis effect.
Thus, Winds and ocean currents are evidence for the process of regulating and stabilizing the climate patterns.

Answer:
Yes.
Explanation:
Substances are made up of matter or matter are made up of tiny molecules or atoms that occur naturally or some are synthetic or man made.
All matter are made up of substances called elements and each elements have its own physical and chemical properties and cannot be broken easily by ordinary chemical reactions.
Of all the 118 elements only 92 occur naturally and 26 are man made or synthetic which are made in the laboratories.
