Mei beg current scientific knowledge says that there is no liquid water on earth's moon. under what circumstances is it acceptable for a group of scientists to report evidence of water on the moon? only if new observations lead to a change in our current knowledge if the scientists wanted to set up a space station on the moon if the scientists believed that all objects in the solar system should have water on them if a news report speculated that water exists on the moon when scientists serve in advisory roles to society, they must be careful to present only objective facts insert personal political views into the advice place their own moral views above the needs of society ignore the needs of the environment and focus only on making money if a fire should begin at your station, you must immediately throw water on it to eliminate the fire. true false it is equally accurate to measure volumes with a beaker as with a graduated cylinder. true false when measuring the volume of a liquid in a graduated cylinder, you should raise the cylinder up to eye level to read the meniscus more accurately. true false a mixture of sand and iron filings can be separated into its individual components by using a magnet. true false the best way to separate ethanol from its solution in water is to use which of the following? chromatography precipitation distillation filtration for an electrically neutral atom, the number of protons is equal to: the number of neutrons the sum of neutrons + electrons the difference of neutrons − electrons the number of electrons if the number of protons for an element changes, then: the element turns into an isotope the element becomes a different element the number of electrons for that element changes as well the number of neutrons changes as wellgenerally, when going from left to right across a period on the periodic table: atomic radii decreaseionic radii decreasesvalence electron number decreasesgenerally, when going down a group on the periodic table, the ionization energy: the same except for noble gasesremains the same except for halogens
