When the following redox equation is balanced with smallest whole number coefficients, the coefficient for nitrogen dioxide will
Phoenix [80]

In a redox reaction, electron could be lost or gained. The coefficients in the balanced redox reaction are;  1/2, 5, 1, 5, 2, 1.

<h3>What is a redox reaction equation?</h3>

A redox reaction equation shows the species that were oxidized or reduced in a redox reaction. In this case, we are asked for the coefficients in a balanced redox reaction equation.

We must recall that five electrons were lost/gained in the process hence the balanced reaction equation is;

1/2I2 + 5HNO3 -----> IO3^- + 5NO2 + 2H2O + H^+

The coefficients in the balanced equation therefore are; 1/2, 5, 1, 5, 2, 1.

What Can bond together to form an ionic bond?
Kazeer [188]

Answer:

An ionic bond forms between two ions of opposite charges. In ionic bonding, electrons transfer from one atom to another. The elements take on either a negative or positive charge. Ions are another name for charged atoms. Some elements are electropositive, and some are electronegative.

Hope this helps!

Some antacid tables contain aluminum hydroxide. The aluminum hydroxide reacts with stomach acid according to the equation: Al(OH
MatroZZZ [7]

Answer:

26.67 mol HCl

Explanation:

Al(OH)₃ + 3HCl → AlCl₃ + 3H₂O

In order to solve this problem, we need to c<u>onvert Al(OH)₃ moles to HCl moles</u>.

To do so we use the<em> stoichiometric ratios</em> of the balanced reaction:

  • 8.89 mol Al(OH)₃ * \frac{3molHCl}{1molAl(OH)_{3}} = 26.67 mol HCl

Thus 26.67 moles of HCl would react completely with 8.89 moles of Al(OH)₃.
