Answer:
chemical
Explanation:
Some bronze objects tarnish to a dark brown color. Chemical properties can be identified by the changes they produce. The change of one substance into another substance is called a A piece of wood burning, an iron fence rusting, and a silver spoon tarnishing are all examples of chemical changes.
Answer:
it depends on the subject but i can see what i can do
Explanation:
Explanation:
First, we will calculate the entropies as follow.
J/K mol
As, = 298 K, = 373.8 K
Putting the given values into the above formula we get,
J/K mol
=
= 18.5 J/K mol
Now,
=
= 94.2 J/mol K
Also,
=
= 33.4 J/K mol
Now, we will calculate the entropy of one mole of methanol vapor at 800 K as follows.
= (126.8 + 18.5 + 94.2 + 33.4) J/K mol
= 272.9 J/K mol
Thus, we can conclude that the entropy of one mole of methanol vapor at 800 K is 272.9 J/K mol.
Answer :
Saturated hydrocarbon : 3-methyloctane, propane, heptane.
Unsaturated hydrocarbon : cyclopentene, heptyne
Explanation :
Saturated hydrocarbon : These are those hydrocarbons in which all carbon atoms and hydrogen atoms are bonded together with single bonds.
For example : Methane, Ethane, etc.
Unsaturated hydrocarbon : These are those hydrocarbons in which carbon-carbon atom bonded together with double or triple covalent bonds.
For example : Ethene, Butyne, etc.
Therefore, the saturated and unsaturated hydrocarbons are:
Saturated hydrocarbon : 3-methyloctane, propane, heptane.
Unsaturated hydrocarbon : cyclopentene, heptyne
Reaction:
FeCl3(aq) + 3AgNO3(aq) → Fe(NO3)3(aq) + 3AgCl(s)
Net ionic:
Ag + (aq) + Cl − (aq) → AgCl(s)
Explanation:
The evidence that a double replacement reaction has happened is the formation of a solid, liquid or gas from aqueous solutions. I’m this case case silver chloride is a precipitate.
