A student is using the periodic table to find information for a report on elements. One of the statements about fluorine in her report contains an error. Find the error, and write your replacement for the error beneath the statement. Flourine is a halogen in group 17. Its chemical symbol is F. It is atomic number 9 and has 7 valence electrons. Flourine has a low reactivity compared to many other elements.

An aqueous solution of hydroiodic acid is standardized by titration with a 0.186 m solution of calcium hydroxide. if 26.5 ml of base are required to neutralize 20.3 ml of the acid, what is the molarity of the hydroiodic acid solution? m hydroiodic acid

How many moles of oxygen gas are produced from the decomposition of six moles of potassium chlorate

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
