Answer:

False

Explanation:

''A mixture is the chemical bonding of two or more substances in any proportion'' is false statement because a mixture don't include bonding of chemical substances.  

Mixtures in chemistry are including <u>blending</u> of substances and we have two tipes of mixture:

  1. Heterogeneous
  2. Homogeneous

Some of the chemical mixtures are: mixture of water and sand, mixture of sand and iron filings and more...

If we are talking about bonding in chemistry there are Covalent bonds and Ionic bonds.

<u>Answer:</u>

<em>The statement is False. </em>

<u>Explanation:</u>

A mixture contains two or more elements present in it.

The elements are not in chemical combination with each other.

A compound too contains two or more elements but they are in chemical combination.

For example NaCl  is a compound which contains 1 part of Sodium and 1 part of Chlorine.

H_2 O is a compound 2g of hydrogen is chemically combined with 16g of Oxygen.

Chemical bonding is the attractive forces  which holds the atoms together in a molecule.

NaCl - the attractive force is called as Ionic bond.

H_2 O - the bond present is a covalent bond

A mixture has two or more elements but there is no chemical bonding present in it. The components of a mixture can be easily separated from it.

sergij07 [2.7K]

Answer:

Hydrogen peroxide should be stored in

1) a cool environment

2) with amber bottles away from sunlight

3) with little drops of sodium phosphate

Explanation:

It has been confirmed that heat and light aids in the decomposition of hydrogen peroxide according to the equation; 2H2O2→2 H2O + O2.

This means that hydrogen peroxide must be stored in a cool place. This will reduce its rate of decomposition. Secondly, it should be stored in amber bottles away from light since light also aids in its decomposition.

Thirdly, drops of sodium phosphate may be added to prevent its catalytic decomposition during storage.
