What happens to rock during subduction please help I will give you Brainlyest
1 answer:
Answer: Here is the answer!! :)
Explanation:
A subduction zone is a region of the earth's crust where one tectonic plate moves under another tectonic plate; oceanic crust gets recycled back into the mantle and continental crust gets created by the formation of arc magmas. ... This water lowers the melting point of mantle rock, initiating melting.
Here is a graph to understand it better!:)

Answer: 18.97 L
Explanation:
This can be solved by the Ideal Gas equation:
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas in Kelvin
Finding :
Therefore:
The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is <u>18.97</u> liters
Answer: The empirical formula of the compound is
Explanation:
Empirical formula is defined formula which is simplest integer ratio of number of atoms of different elements present in the compound.
Percentage of iron in a compound = 36.76 %
Percentage of sulfur in a compound = 21.11 %
Percentage of oxygen in a compound = 42.13 %
Consider in 100 g of the compound:
Mass of iron in 100 g of compound = 36.76 g
Mass of iron in 100 g of compound = 21.11 g
Mass of iron in 100 g of compound = 42.13 g
Now calculate the number of moles each element:
Moles of iron=
Moles of sulfur=
Moles of oxygen=
Divide the moles of each element by the smallest number of moles to calculated the ratio of the elements to each other
For Iron element =
For sulfur element =
For oxygen element =
So, the empirical formula of the compound is
