QUËSTIONS :- what are the difference between ionic bond and covalent bond?
IONIC BONDS :- THEY R BONDS WHICH R FORMED DUE TO THE COMPLETE TRANSFER OF ELECTRONS BETWEEN TWO ATOMS
COVALENT BONDS :- THEY R THE BONDS WHICH R FORMED DUE TO INCOMPLETE TRANSFER OF ELECTRONS BETWEEN TWO ATOMS
IONIC BONDS R MORE STRONGER.
Answer:
-470.4 kJ/mol
Explanation:
Balanced reactions equations are as follows.
CaC2 (s) + 2H2O (l) â C2H2 (g) + CaOH2 (s) ÎH=â414.kJ
6C2H2 (g) + 3CO2 (g) + 4H2O (g) â 5CH2CHCO2H (g) ÎH=132.kJ
To get the 6 C2H2 we need to multiply first equation by 6
Then we get
6CaC2 (s) + 12H2O (l) â 6C2H2 (g) + 6CaOH2 (s) ÎH=â414.kJ * 6 = -2484 kJ
6C2H2 (g) + 3CO2 (g) + 4H2O (g) â 5CH2CHCO2H (g) ÎH=132.kJ
So the total energy produced = -2484 kJ + 132.0 kJ = -2352 kJ
This amount of energy is given out for the 5 moles of acid
So lets convert it for 1 mol
-2352 kJ * 1 mol / 5 mol = -470.4 kJ/mol
So the delta H of reaction for the formation of the acrylic acid is -470.4 kJ/mol
Answer:
to see if something or someone has either a low or high temperature
Explanation:
because you wanna know if some has a fever so you dont get the coronna virus
Answer:
When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction. When you increase the pressure, the molecules have less space in which they can move. That greater density of molecules increases the number of collisions.

would u like to do a zoom?
If u can...
im just bored and my friend fell asleep on me :/
