In the oxidation-reduction reaction to form NaCl, which substance is oxidized and which is reduced?

1 answer:

4 0

0 0 +I -I
2Na + Cl₂ ---> 2NaCl

Oxidation:
Na ----> Na⁺ + e⁻

Reduction:
Cl₂ + 2e⁻ ---> 2Cl⁻

Na is oxidized
Cl₂ is reducted

How do you calculate the number of valence electrons in an atom?

gavmur [86]

To find the valence electrons in an atom, identify what group the element is in. An element in group 1A has 1 valence electron. For example, Li is in group 1A, so that means it has one valence electron. If the element is in group 2A, then it has two valence electrons.

what happen when zinc is put in concentrated sodium hydroxide.explain with the help of balance chemical equation

Dmitry_Shevchenko [17]

Zinc is amphoteric which means it reacts with both acids and alkalis.
The balanced equation is: Zn + 2NaOH + 2H2O --> Na2Zn(OH)4 + H2(g).
Sodium zincate and hydrogen gas are the products.

To make a 450g solution with a mass by mass concentration of 7%, how much salt and water do you need to mix?

Yuri [45]

Explanation:

The given data is:

The mass% of a solution is 7.

Mass of solution =450g

The mass of salt required can be calculated as shown below:

$mass percent =(mass of solute/mass of solution )x100\\$

Substitute the given values in this formula to get the mass of solute that is salt:

$mass percent =(mass of solute/mass of solution )x100\\\\7=\frac{mass of salt}{450g} x100\\=>mass of salt=7x450g /100\\mass of salt=31.5g$

Mass of salt =31.5g

Mass of solvent that is water = 450g-31.5g=418.5g
