Increasing the temperature a reaction takes place at increases the rate of reaction. At higher temperatures, particles can collide more often and with more energy, which makes the reaction take place more quickly. ... Both reactions release a gas and both finish at the same volume .

Answer:
∆G°= -55005J or -55KJ
Explanation:
The first step is to determine E°cell= E°cathode - E°anode
2Cl-(aq)/Cl2(g) system is the cathode while 2Br-(aq)/Br2(g) is the anode
E°cell= 1.360-1.075
E°cell= 0.285V
From
∆G°= -nFE°cell
n= 2 from the balanced reaction equation, two electrons were transferred.
F= 96500
E°cell=0.285V
∆G°= -(2×96500×0.285)
∆G°= -55005J or -55KJ
Density is defined as Mass per unit volume of an object ~
And hence, the correct choice is ~ 1
The final volume : 3.4 L

Charles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
V₁=3300 ml
T₁=63 + 273=336 K
T₂=78+273=351 K
the final volume :
Answer:
The answer to your question is 0.41 moles
Explanation:
Data
moles of NaCl = ?
mass of NaCl = 24 g
Process
To solve this problem just calculate the molar mass of NaCl, and remember that the molar mass of any substance equals to 1 mol.
1.- Calculate the molar mass
NaCl = 23 + 35.5 = 58.5 g
2.- Use proportions and cross multiplication
58.5 g of NaCl ------------------- 1 mol
24.0 g ------------------- x
x = (24 x 1) / 58.5
x = 0.41 moles
