A.) 3 H2SO4 + 2 Al > Al2(SO4)3 + 3 H2 6 H+ +3 S +12 O +2 Al> 2 Al + 3S + 12O + 6H+ This one is balanced, with 6 H, 3 S, 12 O, and 2 Al on both sides. B.) 2KCl + Pb(NO3)2 > KNO3 + PbCl2 2K + 2Cl + Pb + 2N +6 O > 1 K + 1 N+ 3 O + Pb + 2 Cl This one is not balanced as there is 2 K, 6 O and 2 N on the reactants side but only 1 K, 3 O, and 1 N on the products side. Therefore, only A.) is balanced
Only equation A is balanced. To balance equation B, simply add another molecule of KNO3, so the final equation would be: 2KCl + Pb(NO3)2 ---> 2KNO3 + PbCl2
Explanation:because The chemical energy in the food you eat is changed into another kind of chemical energy that your body can use. Your body then uses that energy to give you the kinetic energy that you use in everything you do.
Zinc density = 7.10 = 46.77/x ==> x = 46.77/7.10 =6.6 cm3 or 6.6 ml New water level = 33.33+ 6.6 = 39.93 ml Can you mark it brainliest if my answer is correct?
