What is the difference between an open system and a closed system?

Draggable itemarrow_right_altCorresponding Item

closed system

arrow_right_alt

systems that can result in a lower mass of the reactants in the products

open system

arrow_right_alt

systems that always result in an equal mass of the reactants in the products

Hydrogen & oxygen react chemically to form water.

How much water (H₂O) would form if

14.8g of hydrogen (H₂) reacted with 34.8g of oxygen (O₂)?

(H₂ + O₂ → H₂O)

When ammonium nitrate (NH₄NO₃) explodes, the products are nitrogen, oxygen, & water.

When 40g of ammonium nitrate explode, 14g of nitrogen and 8g of oxygen form. How many grams of water form?

(NH₄NO₃ → N₂ + O₂ + H₂O)
