It makes your clothes smell great
Answer:
on the right side two and on left side it is6 yes it is a balanced equation pls mark me as the brainliset hope it helps you
During the riding of the steep mountain, the body needs more energy because going up consume more energy and oxygen due to additional effect of gravity on your momentum.
<h3>What is the effect of cycling?</h3>
Cycling is a good exercise as swimming, while cycling, happy hormones are released like dopamine and serotonin.
The primary forces that work while cycling are gravity, friction, rolling resistance, and air resistance.
Thus, During the riding of the steep mountain, the bod needs more energy because going up consume more energy and oxygen due to additional effect of gravity on your momentum.

A. Zn²⁺
<h3>Further explanation</h3>
Given
Cations of several elements
Required
The least to be reduced
Solution
If we look at the voltaic series:
<em>Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe²⁺-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Fe³⁺-Ag-Pt-Au </em>
The electrode which is easier to reduce than the hydrogen (H2) electrode has a positive sign (E red= +) and is located to the right of the voltaic series (right of H)
The electrode which is easier to oxidize than the hydrogen (H2) electrode and is difficult to experience reduction has a negative sign (E red= -) and is located to the left of the voltaic series (left of H)
Or you can look at the standard reduction potential value of the metals in the answer options, and the most negative reduction E° value which will be difficult to reduce.
The Zn metal is located far left of the other metals in the answer choices, so it is the most difficult to reduce
