The equations are not balanced. which equation would have the same coefficients in the same order as 2co2 + 3h20 → c2h6o + 3o2?

al + feo → al2o3 + fe
ch4 + o2 →co2 + h2o
pcl5 + h2o → hcl + h3po4
fecl3 + nh4oh → fe(oh)3 + nh4cl

Answer : The correct equation that have the same coefficients order is:

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

The given balanced chemical reaction is,

The order of coefficients is, 2, 3, 1, 3

(a) The unbalanced chemical reaction is,

This reaction is an unbalanced chemical reaction because in this reaction number of aluminum and oxygen atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the and the coefficient '3' put before the and then we get the balanced chemical equation.

The balanced chemical reaction will be,

The order of coefficients is, 2, 3, 1, 3

(b) The unbalanced chemical reaction is,

The balanced chemical reaction will be,

The order of coefficients is, 1, 2, 1, 2

(c) The unbalanced chemical reaction is,

The balanced chemical reaction will be,

The order of coefficients is, 1, 4, 5, 1

(d) The unbalanced chemical reaction is,

The balanced chemical reaction will be,

The order of coefficients is, 1, 3, 1, 3

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
