The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. each compound is soluble in water. imagine that a few tenths of a mole of each compound is dissolved in a liter of water. then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. for example, you know water itself will be present, so you can begin each list with the chemical formula for water (h2o).note: "major" chemical species are those present in concentrations greater than 10^-6 mol. major species present when dissolved in waterzinc iodide zni2 nitrous oxide n2osodium nitrate nano2glucose c6h12o6nickel (ii) iodide nil2

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.

Apiece of metal with a length of 1.42 cm was measured using four different instruments. which of the following measurements is the most accurate?

Scientists are often interested in knowing the molar heat of combustion – the heat released during the combustion of one mole of a substance. use the periodic table to find molar masses. how many moles of ethanol are present in the sample?
