Answer:
You cannot reverse the effects.
Explanation:
In physical changes you can usually reverse the effects for example if ice melts you can just refreeze it. But it's impossible to reverse a chemical change such as a rusted bike.
Answer is: <span> </span>ΔG for <span>methylamine is 18.85 kJ/mol.
</span>ΔG = R·T·lnK.
ΔG is Gibbs energy.
<span>T is the temperature on the Kelvin scale.
R is </span><span>ideal gas constant.
R = 8.314 J/mol</span>·K.
T = 25°C = 293.15 K.
Kb = 0.00044.
ΔG = - 8.314 J/mol·K · 293.15 K · ln(0.00044).
ΔG = 18836.85 J = 18.84 kJ.
Answer: 1 molecule of 
reacts with 1 molecule of 
to give 2 molecules of HCl.
1 mole of reacts with 1 mole of to give 2 moles of HCl.
Explanation:
The given balanced reaction is:
On the particulate level :
1 molecule of reacts with 1 molecule of to give 2 molecules of HCl.
On molar level:
1 mole of reacts with 1 mole of to give 2 moles of HCl.
When droplets of water in the atmosphere act like prism the color in the sunlight undergo interferance, making rainbows. ( This is how rainbows form)
They tend to pick at it until it is in small enough pieces to swallow. Then their gizzard (rough muscle) in their stomach acts as internal teeth.
