If countries are on plate boundaries, such as Japan, they are more prone to earthquakes. If countries are above hot spots, such as Hawaii, they are more prone to volcanoes.
Answer:
108.9g of Silver can be produced from 125g of Ag2S
Explanation:
The compound Ag2S shows that two atoms of Silver Ag, combined with an atom of Sulphur S to form Ag2S. We can as well say the combination ration of Silver to Sulphur is 2:1
•Now we need to calculate the molecular weight of this compound by summing up the molar masses of each element in the compound.
•Molar mass of Silver Ag= 107.9g/mol
•Molar mass of Sulphur S= 32g/mol
•Molecular weight of Ag2S= (2×107.9g/mol) + 32g/mol
•Molecular weight of Ag2S= 215.8g/mol + 32g/mol= 247.8g/mol
•From our calculations, we know that 215.8g/mol of Ag is present in 247.8g/mol of Ag2S
If 247.8g Ag2S produced 215.8g Ag
125g Ag2S will produce xg Ag
cross multiplying we have
xg= 215.8g × 125g / 247.8g
xg= 26975g/247.8
xg= 108.85g
Therefore, 108.9g of Silver can be produced from 125g of Ag2S
Deposits
Explanation:
Glaciers also deposits materials in new places when they melt.
- Glaciers are made up of snow flakes that has compressed through time.
- In temperate and polar regions where they are prevalent, they are powerful agents of denudation.
- They can erode, transport and deposit earth materials in places.
- When a glacier retreats by melting, it deposit some of its materials in new places.
- Most of this sediment are called tillites.
- They are made up of unsorted materials of different size grains.
