hich of the following statements is true for the reaction of nitrogen gas with hydrogen gas to produce ammonia (NH3)? Choose the best answer. l type='a'> Subscripts can be changed to balance this equation, just as they can he changed to balance the charges when writing the formula for an ionic compound. i>The nitrogen and hydrogen will not react until you have added the correct mole ratios. i>The mole ratio of nitrogen to hydrogen in the balanced equation is 1:2. i>Ammonia will not form unless 1 mole of nitrogen and 3 moles of hydrogen have been added. i>The balanced equation allows you to predict how much ammonia you will make based on the amount of nitrogen and hydrogen present.
Hydrogen peroxide is used as a cleaning agent in the treatment of cuts and abrasions for several reasons. It is an oxidizing agent that can directly kill many microorganisms: It decomposes upon contact with blood, releasing elemental oxygen gas (which inhibits the growth of anaerobic microorganisms); and it foams upon contact with blood, which provides a cleansing action. In the laboratory, small quantities of hydrogen peroxide can be prepared by the action of an acid on an alkaline earth metal peroxide, such as barium peroxide. BaO2(s)+2HCl(aq)H2O2(aq)+BaCl2(aq) What amount of hydrogen peroxide should result when 1.50 g of barium peroxide is treated with 25.0 mL of hydrochloric acid solution containing 0.0272 g of HCI per mL?
