Sodium oxide and carbon dioxide

Explanation:

When sodium carbonate decomposes sodium oxide and carbon dioxide is produced:

                          Na₂CO₃ → Na₂O + CO₂

  • This kind of reaction is known as decomposition reaction.
  • In a decomposition reaction,
  • In this kind of reaction, two or more products form from a single reactant.
  • The breakdown of a compound into its component individual elements or other compounds falls into this reaction category.

Antimony Sb

Explanation:

The element that will have similar chemical properties with Arsenic As is element Antimony or Sb.

An element is a distinct substance that cannot be split-up  into simpler substances. They are made up of only one kind of atom.

  • The chemical properties of an element is determined mostly by the number of electrons in its outermost shell.
  • This is called the valency of an element.
  • Element having the same valency behaves the same way chemically.
  • They exchange the same number of electrons during chemical reaction.

Therefore, elements in the same group on the periodic table have the same chemical properties.

Elements in the same group have the same valency.

Anitmony and Arsenic belongs to group 5 on the periodic table. The elements in this group are Phosphorus, Arsenic, Antimony and Bismuth.

How many grams of lithium are in a 1320 [mAh] cell phone battery? Note that [mAh] is a unit of charge.
AURORKA [14]

Answer:

0.396 grams of lithium

Explanation:

Lithium-ion batteries have the main feature of using lithium salts as a "bridge" between the positive pole (anode) to the negative (cathode) to allow the passage of energy that will give life to our device. In the case of lithium polymer batteries, the difference is that the lithium salt is contained in a polymer, or gel, to keep it safe from spills.

In both cases, when the battery is discharging, lithium ions travel from the cathode to the anode through their "bridges" to supply the energy until all the ions are in the anode, it is at this time when the battery is out of stock The ions travel in the opposite direction during charging (from the anode to the cathode).

<u>The calculation used to determine the amount of lithium that the lithium cell batteries have is as follows</u>:

0.3 x amp hour capacity = g of lithium

where amp hour = Ah

<u>In our case</u>:

0.3 x 1.32 = 0.396 g of lithium
