Answer:
GAY-LUSSAC'S LAW.
Explanation:
P1 = 765 torr
T1 = 23°C = 296K
P2 = 560. torr
T2 = ?
(765 torr)/(296K) = (560. torr)/ T2
T2 = 226 K = -57°C
Answer:

Explanation:
Heat of combustion of
= -1366.8 kJ/mol
Heat of formation of
= -393.5 kJ/mol
Heat of formation of
= -285.8 kJ/mol
The reaction is

Assuming
is the standard enthalpy of formation of ethanol

The standard enthalpy of formation of ethanol is
.
Answer: Anion. The resulting of losing or gaining electrons would be Anion.
The following are the answers:
=oxygen equals to a charge of 2-
number of atoms is -24
=Mn equals to the charge of +3
Mn= 3+3x-24=0
let x be the charge of Cl, so:
23-3=3x
20/3=x
=6.67 or 7
x= 7
= Cl has a charge of +7
