Answer:
At high temperatures or in the presence of catalysts, sulfur dioxide reacts with hydrogen sulfide to form elemental sulfur and water. This reaction is exploited in the Claus process, an important industrial method to dispose of hydrogen sulfide.
Answer:-
HCl is a volatile acid. It easily evaporates at room temperature. So the concentrated HCl which is supposed to be 12 M is no longer 12 M since some of the HCl has already escaped as vapor.
Hence when a solution of 6M HCl is made from a stock of concentrated HCl by adding an equal volume of water, the concentration of the solution is only an approximate concentration since the concentration of the stock concentrated solution is also approximate.
Answer:
two
Explanation:
When two distinct elements are chemically combined, chemical bonds form between their atoms. the result is called a chemical compound
Answer:
3.73 atm
Explanation:
Since there is no change in temperature, we use Boyle's law.
P₁V₁ = P₂V₂ where P₁ = initial pressure of Ar gas = unknown, P₂ = final pressure of Ar gas = 2.74 atm, V₁ = initial volume of Ar gas = 6.30 L and V₂ = final volume of Ar gas = 8.57 L
P₁ = P₂V₂/V₁ = 2.74 atm × 8.57 L/6.30 L = 3.73 atm
The answer is: They have no freedom to move.
However is not completely true, as even in a solid atoms still a move a bit (vibrations).
If atoms were able to slide past each other, then we would have a liquid not a solid. Liquids "flow" but never really "break apart" this is because atoms are sliding between them, think of these as a bucket of marbles rolling down a slope.
If they are free to move in all directions, then you have a gas; that's why someone uses perfume in a room, eventually everyone smells it.
