Answer:
active galaxies are extremely bright and travel faster than normal galaxies. The mass of active galaxies is confined to a smaller space and they have some activity in their nuclei which produces an enormous amount of energy in a very small volume of space.
The equation that shows the decomposition of silver carbonate is as follows:
2Ag2CO3 > 4Ag + 2CO2 + O2--------------------------------------------------------------------------------------------------okay, now from the periodic table:mass of silver is 107.8682 gramsmass of carbon is 12 gramsmass of oxygen is 16 gramsmolar mass of Ag2CO3 is 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------------------------------------------------------------------------------------------------------Therefore, to know the mass of Ag produced from 2.76 grams of Ag2CO3, we will simply use cross multiplication as follows:mass of Ag produced = (2.76*431.4728) / (551.4728) = 2.16 grams==========================================================
Based on the above calculations, the law of conservation of mass is applied.
hope this helped out ❤❤
The spontaneous emission of radiations from an unstable nuclei is known as natural radioactivity. on the other hand, The process of emission of radiations from naturally occurring isotopes when they are bombarded with sub-atomic particles or high levels of X-rays or gamma rays called artificial radioactivity.
