Question

Balancear a seguinte equação pelo método algébrico:

HNO3 + Ca (OH)2 --> Ca (NO3)2 + H2O

Answer 1

$HNO_{3} +Ca(OH)_{2} -->Ca(NO_{3})_{2}+H_{2}O\\\\H=3\\N=1\\O=5\\Ca=1\\\\H=2\\N=2\\O=7\\Ca=1\\\\2HNO_{3} +Ca(OH)_{2} -->Ca(NO_{3}_{2}+H_{2}O\\\\H=4\\N=2\\ O=8\\ Ca=1\\\\H=2\\N=2\\O=7\\Ca=1\\\\2HNO_{3} +Ca(OH)_{2} -->Ca(NO_{3})_{2}+2H_{2}O\\H=4\\N=2\\O=8\\Ca=1\\\\H=4\\N=2\\O=8\\Ca=1$
