Explanation

Acetamide, which is a primary amide and has the chemical formula CH3CONH2, is typically prepared by heating ammonium acetate.

Here's the reaction:

CH3COO −NH4+ → CH3CONH2 + H2O

In this reaction, ammonium acetate (CH3COONH4) decomposes upon heating to form acetamide (CH3CONH2) and water (H2O).

This process is a type of thermal decomposition reaction.

Explanation

"Alkanoic acid" is another term for carboxylic acid.

Carboxylic acids are organic compounds characterized by the presence of a carboxyl group (-COOH) attached to an alkyl chain.

Examples of carboxylic acids include"

• acetic acid (ethanoic acid)
• formic acid (methanoic acid)
• butyric acid (butanoic acid)
  

Explanation

• Mixtures are physical combinations of two or more substances that are not chemically combined.
• The components of a mixture retain their chemical properties and can be separated by physical means.

Explanation

Melting is the process by which a solid (in this case, ice) changes to a liquid (water) when it is heated and gains energy.

Explanation

The correct answer is: Molecules do not collide with one another

Gas molecules:

• Are widely separated
• Have low attractive forces
• Are free to move in any direction
• Collide with one another

Explanation

There are three main scales used to measure temperature:

1. Celsius scale: Water freezes at 0°C and boils at 100°C.
2. Fahrenheit scale: Water freezes at 32°F and boils at 212°F.
3. Kelvin scale: Absolute zero (the theoretical minimum temperature) is 0K, and water freezes at 273.15K and boils at 373.15K.

Explanation

• Liquids can be converted into gases by heating, a process known as vaporization or evaporation.
• As the temperature increases, the particles of the liquid gain energy and move faster, eventually breaking free from the surface tension of the liquid and turning into a gas.

Explanation

The oxidation of glucose to gluconic acid is a reaction that involves the loss of two electrons:

C6H12O6 (glucose) → C6H12O7 (gluconic acid)

Explanation

• The statement that is not true about the precision of data is: "It is the difference between the obtained value and the true value."

Explanation

• The given reaction (CH4 + Cl2 → CH3Cl + HCL) is an example of a free radical substitution reaction.
• Free radical reactions typically exhibit a constant rate over time, regardless of the concentration of the reactants.
• Therefore, the order of this reaction is Zero order.
