4. Several different batches of drink mix have different appearances. The solution is supposed to be somewhat red in color, but that is not always the case. What do you think went wrong? Provide a plausible reason, consistent with the observations. Scenario 1: The color intensity is too low - it is too pale. Scenario 2: The color intensity is too great - it is too dark. Scenario 3: The solution color is wrong! It looks somewhat blue. Scenario 4: The vat of solution started out with the correct color intensity, but over time the appearance changed. The employees are certain nothing was added to the open vat. need help asap​

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.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
