The equation that shows the decomposition of silver carbonate are;

2Ag2CO3 ---------> 4Ag + 2CO2 + O2

From the periodic table:

Mass of silver = 107.8682 grams

Mass of carbon = 12 grams

Mass of oxygen = 16 grams

Molar mass of Ag2CO3 = 2(107.8682) + 12 + 3(16) = 275.7364 grams

From the balanced equation above:

2(275.7362) = 551.4728 grams of Ag2CO3 produces 4(107.8682) = 431.4728 grams of Ag

Thus, in order to know the mass of Ag produced from 2.76 grams of Ag2CO3, we'll use the cross multiplication method;

Mass of Ag produced = (2.76 × 431.4728) / (551.4728) = 2.16 grams

Based on the calculations demonstrated above, the law of conservation of mass is applied.

What is a karyotype? a. a system of classifying cell nuclei b. a unique combination of chromosomes found in a gamete c. the set

Sergio039 [100]

Answer:

Option (d).

Explanation:

Karyotype may be defined as the process of the determining of the chromosome complement of the individual organism. The complete set of an organism's chromosome can be determined by karyotype.

The karyotype displays the each and every pair of homologous chromosome. The chromosomes are organised according to their shape and size. The abnormal chromosome can easily be determined by the karyotype.

Thus, the correct answer is option (d).
