Answer:

1

Explanation:

A decomposition reaction is a chemical reaction in which one product is decomposed to form two or more products. In chemistry, decomposition is primarily achieved by heating the substance at high temperature.

Chlorates normally are decomposed when they are reached at a significant high temperature and are normally used for oxidation purposes. In the given examples from the table:

Sodium chlorate is decomposed to Sodium chloride and oxygen. Potassium chlorate follow the same principle and so will Lithium.

So, the reaction becomes:

2LiClO₃ ----> 2LiCl + 3O₂

You can see that both Sodium chlorate (NaClO3) and Potassium chlorate (KClO3) gave exactly the same products. i.e. a chloride and oxygen.

Calculate the mass percent of 0.485 g of H, which reacts with oxygen to form 2.32 g H2O
Nataly [62]

Answer:

Mass % of hydrogen = 20.9 %

Explanation:

Given data:

Mass of hydrogen = 0.485 g

Mass of water = 2.32 g

Mass percent of hydrogen = ?

Solution:

Mass % of hydrogen = mass of hydrogen / mass of water × 100

Mass % of hydrogen = 0.485 g/ 2.32 g × 100

Mass % of hydrogen = 0.209  × 100

Mass % of hydrogen = 20.9 %

A piece of mental with a mass of 106 g is placed in a 50 mL graduated cylinder.The volume rises from 20 mL to 31 mL. What is the
garik1379 [7]

Answer:

9.64g/mL

Explanation:

Given parameters:

Mass of the metal  = 106g

Volume of cylinder = 50mL

Volume difference  = 31mL  - 20mL  = 11mL

Unknown:

Density of the metal  = ?

Solution:

To find the density of the metal, we use;

 Density  = \frac{mass}{volume}  

 Density  = \frac{106}{11}   = 9.64g/mL
