Explanation:
The term suspension means mixing of small and light particles together which are not dissolved in a fluid.
Therefore, clay, slit, and sand would be carried by suspension as they have small particles as compared to small pebbles and large rocks.
In a rock, there might be substance which are soluble in water. These soluble substances are therefore, continuously removed from the rock by the action of water.
Hence, holes will appear in the rock leading to rills and rough surface. Ultimately, the rock will either decompose or fall into pieces. On acidification of water by organic and inorganic solvents, the dissolution of rock increases.
Thus, it is concluded that in solution, rocks are dissolved by salts and acids.
Explanation:
The states may differ depending on the reactions
Answer:
60 moles of NaF
Explanation:
The balanced equation for the reaction is given below:
Al(NO3)3 + 3NaF —> 3NaNO3 + AlF3
From the balanced equation above,
3 moles of NaF reacted to produce 1 mole of AlF3.
Therefore, Xmol of NaF will react to produce 20 moles of AlF3 i.e
Xmol of NaF = 3 x 20
Xmol of NaF = 60 moles
Therefore, 60 moles of NaF are required to produce 20 moles of AlF3.
The given question is incomplete. The complete question is :
Gaseous butane reacts with gaseous oxygen gas to produce gaseous carbon dioxide and gaseous water . If 1.31g of water is produced from the reaction of 4.65g of butane and 10.8g of oxygen gas, calculate the percent yield of water. Be sure your answer has the correct number of significant digits in it.
Answer: 28.0 %
Explanation:
To calculate the moles :
According to stoichiometry :
13 moles of 
require 2 moles of butane
Thus 0.34 moles of will require=
of butane
Thus is the limiting reagent as it limits the formation of product and butane is the excess reagent.
As 13 moles of give = 10 moles of 
Thus 0.34 moles of give =
of
Mass of 
The percent yield of water is 28.0 %
