2.
Calculate the heat of reaction for the following process:
3 FeCl2 → Fe + 2 FeCl3,
given the following info:
Fe + 2HCl → FeCl2 + H2H
2 Fe + 6 HCI → 2 FeCl3 + 3 H2
1822
AH = -769 kJ
AH = 41822 kJ
3. Calculate the heat of reaction for the following reaction:
Fe + 2 Agri → 2 A Coru

no but i do not usually comment or use my voice that much when it comes to social media

it would be a gas formation

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
