How does redox lift a space shuttle

Using Numbers The space shuttle gains nearly 72% of its lift from its solid rocket boosters (SRBs) during the first two minutes of launch. The two pencil-shaped SRB tanks are attached to both sides of the liquid hydrogen and oxygen fuel tank. Each SRB contains 495 000 kg of an explosive mixture of ammonium perchlorate and aluminum. The unbalanced equation for the reaction is given below. [Pg.647]

A Oafg) + HCI(g) + N2(g) + H20(g) Use the oxidation-number method to balance this redox equation. [Pg.647]

The SRB reaction can be balanced using the rules for assigning oxidation numbers. In this way, you can ensure that the oxidation reaction balances the reduction reaction. Write the oxidation number above each element in the equation. Which elements are reduced and which are oxidized What coefficients are required to balance the reaction [Pg.647]

What are some of the benefits of using SRBs for the first two minutes of launch [Pg.647]

Oxidation number of the most electronegative element is the same as the charge it would have as an Ion. [Pg.648]
