Can someone please help and I will mark you as brainlist!! 1) which of the following statements is NOT correct?

• coefficient is the number written in front of reactant and product in a chemical equation

• ideal gases follow the assumptions of the kinetic- molecular theory

• none of the above

• to find the volume of a gaseous reactant or product in a reaction, you must know at least one other gas involved in the reaction

2) which is INCORRECT after gasses

• all gas particles have some volume, however small, and are subject to intermolecular interactions

• most gases behave like ideal gases at wide range of temperature and pressure

• none of the above

• the collision that particles make with each other and the with the container are not perfect elastic

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.
