Answer:
2.8x10^24
Explanation:
To convert moles to molecules, multiply the number of moles by Avagadro's number (6.02x10^23. Round if required.
4.62mol × 6.02x10^23 = 2.8x10^24
Answer:
Cell membrane
B
Explanation:
Capsules, fimbriae, pili, flagella, and even the cell wall
Chris is correct because the reactants and products do not have to have the same mass, but they do have to weigh the same. Is the correct answer:) Hannah is right because the mass of the reactants was different than the mass of the products. is incorrect
Explanation:
In chemistry, a mole is the base unit of the amount of substance in a system containing elementary entities (atoms, molecules, ions, electrons), and one mole of substance corresponds to the Avogadro's constant or 
entities. The stoichiometry equation that relates the amount of substance into the measurement in moles is
,
where 
is the number of moles, 
is the amount of substance and 
is the Avogadro's constant.
Therefore,
.
Answer:
<h3><em>Calcium carbonate is heated strongly until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.</em></h3>
