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.

For each of the esters provided, identify the alcohol and the carboxylic acid that reacted.
Veronika [31]

Answer:

52. The alcohol USED => methanol, CH3OH

The carboxylic acid USED => propanoic acid, CH3CH2COOH.

53. The alcohol USED => Ethanol, CH2CH3OH

The carboxylic acid USED => Formic acid, HCOOH.

Explanation:

52. To obtain Methyl propanoate, CH3CH2COOCH3, we simply react propanoic, CH3CH2COOH and methanol, CH3OH together as shown below:

CH3CH2COOH + CH3OH —> CH3CH2COOCH3 + H2O

The alcohol used: methanol, CH3OH

The carboxylic acid used: propanoic acid, CH3CH2COOH.

53. To obtain Ethyl methanoate, HCOOCH2CH3, we simply react

Formic acid, HCOOH and ethanol, CH3CH2OH together as show below:

HCOOH + CH3CH2OH —> HCOOCH2CH3 + H2O

The alcohol USED => Ethanol, CH2CH3OH

The carboxylic acid USED => Formic acid, HCOOH.
