Answer: Multiple answers to this question. This is what I comprehend.

Explanation:

Upon analysis of the results, a theory can be rejected or modified, but it can never be proven to be correct 100 percent of the time. For example, relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true.

<h2>Acetic Acid</h2>

Explanation:

  • Initial alcohol that is formed from methane is methanol that can be converted to acetic acid.
  • Methanol in presence of CO_2 and hydrogen gas gets oxidized to acetic acid with the release of water.

Hence, compound A will be Acetic acid.

CH_3OH + CO_2 +H_2 → CH_3COOH + H_2O

  • The acetic acid formed can be transformed into -
  1. CH_3COOH → CH_4 + CO

        The product formed is methane and carbon monoxide.

    2. CH_3COOH → CH_2CHO + H_2O

         The product formed is formaldehyde and water.

    3. CH_3COOH + NaHCO_3 → CH_3COONa +CO_2 +H_2O

         The product formed is sodium acetate, carbon dioxide, and water.

A balance reads an object A to be 45.1 kg. The balance reads another object B to be 33.46 kg. What is the total weight of both o
postnew [5]

Answer:

The total weight of both object is 78.56 kg.

Explanation:

Given data:

Mass of object A = 45.1 kg

Mass of object B = 33.46 kg

Total weight of object = ?

Solution:

Total weight of both subject must be the sum of weight of object A and B.

Total weight of objects = weight of object A + weight of object B

Now we will put the values of mass of object A and B.

Total weight of objects = 45.1 kg + 33.46 kg

Total weight of objects =78.56 kg

Thus the total weight of both object is 78.56 kg.
