In an experiment, potassium chlorate decomposed according to the following chemical equation.
KCIO3 → KCI + O2
(Molar mass of KCIO3 = 122.5 g/mol; KCI = 74.55 g/mol; O2 = 31.998 g/mol)
If the mass of potassium chlorate was 240 grams, which of the following calculations can
be used to determine the mass of oxygen gas formed? (4 points)

Why are the trends and exceptions to the trends in ionization energy observed?

Acamcorder has a power rating of 17 watts. if the output voltage from its battery is 7 volts, what current does it use?units:

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
