How many atoms of magnesium nitride (Mg3N2 ) (molar mass: 96.93 g/mol) is needed to react with an excess amount of potassium oxide to produce 11.6 liters of magnesium oxide (MgO) (molar mass: 40.30 g/mol)?

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold

Which property of a rock remains unchanged by mechanical weathering? a. total surface area b. size and shape c. mineral composition d. sharpness

Which states of matter have particles that move independently of one another with very little attraction?
