Sodium hydrogencarbonate decomposes on heating: 2 NaHCO3(s) → Na2CO3(s) + H2O(g) + CO2(g)
If 3.36 g of sodium hydrogencarbonate is heated calculate:
the number of moles of sodium hydrogencarbonate used

An object becomes electrically charged when: electrons are created in it electrons from it are destroyed electrons are transferred to it protons from it are destroyed protons are created in it

According to le chatelier’s principle, a system in chemical equilibrium responds to stress by shifting the equilibrium in a direction that reduces the stress. normalizes the stress. increases the stress. changes the stress.
