Answer:
0.1 moles of electrons
Explanation:
Electroplating is a process in which a metal is used to cover the surface of another metal for protection or beautification purposes.
The reduction of the silver is captured in the equation;
Ag^+(aq) +e ------> Ag(s)
We were already told in the question that the mass of silver is 108g
1 mole of electrons is needed to deposit 108g of silver
x moles of electrons is required to deposit 10.8 g of silver
x= 1 ×10.8/108
x= 0.1 moles of electrons
The answer would be salt Water hope I helped you
Answer:
7.46 g
Explanation:
Equation for the reaction can be represented as:
1 mole of phosphoric acid is equivalent to 1 mole of ammonium phosphate in the above reaction; and as such;
numbers of moles of phosphoric acid = numbers of moles of ammonium phosphate
Given that the mass of phosphoric acid = 4.9 g; we can determine the number of moles of phosphoric acid in the process.
mass = 4.9 g
molar mass = 98 g/mol
numbers of moles =
= 0.05 mole
Therefore, the mass of ammonium phosphate can be determine:
mass = number of moles × molar mass
mass of ammonium phosphate = 0.05 mole × 149.09 g/mol
mass of ammonium phosphate = 7.4545 g
mass of ammonium phosphate ≅ 7.46 g
Answer:
Cell growth usually refers to cell proliferation, the increase in cell numbers that occurs through repeated cell division. Cell growth can also refer to the enlargement of cell volume, which can take place in the absence of cell division. As living things grow, some cells die or become damaged and need replacements. Some single-celled organisms use a type of mitosis as their only form of reproduction. In multicellular organisms, cell division allows individuals to grow and change by expanding the number of total cells.
