Realice el balanceo de las siguientes ecuaciones por el método redox KMnO4 + K2SO3 + HCl ⇌ MnO2 + K2SO4 + KCl + H2O K2Cr2O7 + H2S + HCl ⇌CrCl3 + S + KCl + H2O

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
