Answer:
D
Explanation:
Because the other answers can not to be considered to be chemical properties.
Chemical means that the after the reaction the checal properties have changed in a way that it can no longer be called the same ad befor. In short, it can not be undone.
Burning a match is irriversable, meaning you can never go back to the previous situation because the chemical compounds have changed (dramatically).
Melted ice can be frozen again. Steam (evaporated water) can condensate to water which can be heated and can boil again. The chemical contents remain H2O.
Answer:
2.19L
Explanation:
Information from the question include:
V1 (initial volume) = 2.3L
P1 (initial pressure) = 725mmHg
P2 (final pressure) = 760mmHg
V2 (final volume) =?
With the Boyle's law equation P1V1 = P2V2, the final volume can easily be obtain as follow:
P1V1 = P2V2
725 x 2.3 = 760 x V2
Divide both side by 760
V2 = (725 x 2.3)/760
V2 = 2.19L
Therefore, the new volume of the gas at standard pressure is 2.19L

this is your aur answer thank you for calcium test of tetraoxosulphate
Answer:
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions .
