Answer:
the temperature changes finally to 339k because of the increase in pressure of the gas
H2 <span>because the smaller the gas molecule, the faster the diffusion. (the lightest molecule will diffuse the quickest)</span>
Answer:
B). The equivalence point is where the amount of acid equals the amount of base during any add-base titration.
Explanation:
Equivalence point -
During the process of titration of the neutralization reaction , like acid - base reaction .
In the titration process , the equivalence point is the point , when the amount of acid is equal to the amount of base .
In indicator used for th process is pH sensitive ,
It is not always necessary to have pH = 7 at the equivalence point ,
The titration curve is plotted for the pH v/s base .
Hence , from the given options , the correct statement is ( B ) .
Answer:
the first and second one are both already balanced but the third one is
Caco3->Cao+Co2
Answer:
double-protected
Explanation:
If a package is inside a package, the item inside the second package is double-protected, because the outer package will keep it safe.
Hope this helps!
