5 0

Answer:

Explanation:

Reaction given

6 H⁺ + 2 MnO₄⁻ + 5 (COOH)₂ = 10CO₂ +8H₂O + 2 Mn⁺²

Oxidation number of Mn in MnO₄⁻

=  x - 4 x 2 = -1

x = 8 -1

+ 7

Oxidation no of Mn in Mn⁺² =  +2

So its oxidation no is decreased from + 7 to + 2  . Hence it is reduced.

In order to do multiple trials of an experiment, _____. A. change your hypothesis B. do the experiment more than once C. revise
Arisa [49]

B. do the experiment more than once

Explanation:

To do a multiple trials of an experiment, it is best to do the experiment more than once.

Experimental trials are mere replication of the procedures in an experiment.

  • Most hypothesis on which experiments are based must be repeatable.
  • When experiments are repeated through several trials, their accuracy is increased.
  • Multiple trials clearly makes it easy to make meaningful deductions from an experimental process.
