According to Lavoisier's law, in the given reaction the mass of zinc produced will be 104 g.
Let's consider the following reaction.
Ca + ZnCO₃ ⇒ CaCO₃ + Zn
64g 192 g 152 g ? g
<h3>What does Lavoisier's law state?</h3>
Lavoisier's law states that the sum of the masses of the reactants before the reaction is equal to the sum of the masses of the products after the reaction.
mCa + mZnCO₃ = mCaCO₃ + mZn
mZn = mCa + mZnCO₃ - mCaCO₃
mZn = 64 g + 192 g - 152 g = 104 g
What would be the amount of zinc formed during the reaction?
- The mass of zinc produced will be 104 g. TRUE.
- The mass of zinc will be the same as that of zinc carbonate. FALSE.
- The mass of zinc produced will be 52 g. FALSE.
- The mass of zinc will be the same as that of calcium. FALSE.
According to Lavoisier's law, in the given reaction the mass of zinc produced will be 104 g.

Explanation:
Scientists didnt belive that there are cells untill robert hooke (1665). He observed the cells in a cork slice with the help of a PRIMITIVE microscope
Leeuwenhoek (1674), with the help of an improved microscope, discovered free living cells in pound water for the first time.
It was robert brown in (1831) who discovered the nucleus in the cell.
Purkinjie in 1839 coined the term 'protoplasm' for the fluid substance of the cell.
THE CELL THEORY, that all plants and animals are composed of cells and that the cell is the basic unit of life, was presented by two biologists, schleiden (1838) and schwann(1839). The cell theory was fuether expanded by virchow (1855) by suggesting that all cells aris form PRE-EXISTING cells. With the discovery of the electron microscope in 1940,it was possible to observe and understand the complex structure of the cell and its various organelles.
Well, thats the history of the discovery of cells.
Answer:
The correct answer is The drug binds to the 30S small ribosomal subunit eukaryotes have 40S small sub unit.
Explanation:
Tetracycline belongs to broad spectrum antibiotic.Tetracycline is named so because it contain a derivative of four hydrocarbon rings.
Tetracycline act by inhibiting the protein synthesis process in prokatotes by binding to the small ribosomal subunit also called 30S subsunit and blocks the binding of amino acyl tRNA to the A site or attachment site of ribosome.
As eukaryotes contain 40S ribosomal subunit,it becomes difficult for tetracycline to bind with 40S ribosomal subunit of eukaryotes.
Yes, because vaccines help prevent diseases whereas antibiotics help cure them. (it’s better to prevent)
