How many moles of silver(I) bromide are produced when #6.45# moles of sodium bromide take part in the reaction? In one reaction, 0.507 mole of #SiCl_4# is produced. Answer: Mole ratio NH3: N2 = 4:2 Explanation: The given equation depicts the reaction between ammonia (NH3) and oxygen (O2) to form nitrogen (N2) and water (H2O).
