<u>The equation that shows the decomposition of silver carbonate are;</u>
2Ag2CO3 ---------> 4Ag + 2CO2 + O2
<u>From the periodic table:</u>
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
<u>From the balanced equation above:</u>
2(275.7362) = 551.4728 grams<em> of</em> Ag2CO3 <em>produces</em> 4(107.8682) = 431.4728 <em>grams of Ag</em>
<u>Thus, in order to know the mass of Ag produced from 2.76 grams of Ag2CO3, we'll use the cross multiplication method; </u>
Mass of Ag produced = (2.76 × 431.4728) / (551.4728) = <em>2.16 grams</em>
Based on the calculations demonstrated above, the law of conservation of mass is applied.
A comet always points in the opposite direction of the comet hence why it’s called the tail
<h2>
Answer</h2>
Buffer controls the sudden change in the solution
<h2>
Explanation</h2>
Buffer prevents the sudden change in the pH. They keep the pH of the solution nearly constant. For example, in human Buffer solution helps to regulate the pH of human blood. The normal pH of the human blood is nearly 7.35 to 7.45 and a little change in this pH many leads the serious problems. Carbonic and bicarbonate buffers play a role in maintaining the acid base balance of the blood.
The birds adapted to the changes. Since the large nuts were no longer as abundant because of the large birds, the small birds were left with the smaller nuts. Their larger beaks lost their use since the small nuts did not require such well-structured beaks, so the birds started to develop smaller beaks.
