Question

4. Write balanced chemical equations for the following in the space provided. These are all single displacement reactions. You will need to predict the products formed. Assume a reaction occurs in each case. (a) Zn + HCI → (b) ____KI + __ Brı → _ Zn +_ AgNO3 → (d) aluminum and sulfuric acid (e) magnesium and zinc bromide (f) zinc bromide and chlorine

Answer 1

4) a) 1 Zn + 2 nu - Zola + H₂ After balancing the equation that 1 more in reacts with He to form zell and the we found 2 nuole of 1 mole each 6) 2 ki t 2 Br 2 kBb & Is After balancing the equation were found that a moles of UI reacts with 2 moles of Br, to form a moles kB and 1. mede 22 1 Zn + 2 After balaning the I more of 2n and to foron a mole AgNO₃ - 2 Ag + 20 QNO) equatuor we found that 2 onole of AgNo realfs Ag and I mole AG (NO3),

d) 2 Al + 3 Hy sou 3 > Al₂(SO4)₂ + 3H2 412 (504)3 Aluminium (Al) and sulfuric and (150) undergoes reaction as wellten above, wh 2 nous of Al realf with a moles of Hy sog to form Aluminium sulfate (Al(SO4)3) and 3 moles of Hydrogen (14) e) 1 mg & 1 Zebra Zn + Mg Br. Magnesium and Zinchronu de (Znbr, andergoes reach on as written above, where I suole of zine (zn) and I mole of Magnesium brauude (mgbr) & formed as products. & 1 zebry & 1 - Zilly +2 By Inebromide and chlorine undergoes reaction .
