In each term equation below a blank line shows one term missing the terms may be an elemental symbol a coefficient or a subscript decide which term would balance the equation write the missing term in the second column the. Determine the reactants third column and products forth column of the reaction some reactions may have only one reactant or product and other reactions may have only one reactant or product and other reactions may have multiple reactants or products write your answers in the spaces in the table the first reaction involves sodium chloride not sodium carbon and iodine

the answer is b. dilution

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.
