Answer : The volume of
produced will be, 0.8 liters.
Explanation : Given,
Volume of
= 1.2 L
At STP, 1 mole of substance contains 22.4 L volume of substance.
The given balanced chemical reaction is:

From the balanced chemical reaction we conclude that,
As,
volume of
produced
volume of 
So,
volume of
produced
volume of 
Therefore, the volume of
produced will be, 0.8 liters.
Answer:
Primary active transport
Explanation:
In a cell, the movement of molecules like calcium ions (Ca²⁺), <em>to a region having high solute concentration from a region having low solute concentration, through the cell membrane requires metabolic energy</em> and is known as Primary active transport.
It is given that the concentration of calcium in the cell (0.3%) is greater than the concentration of calcium in the fluid surrounding the cell (0.1%). <em><u>So the calcium ions move into the cell and the cell obtains more calcium. </u></em>
<u>Therefore, the cell obtains more calcium by the process of Primary active transport.</u>
Answer: 30.27 g
Explanation:
Since the silver is in units of atoms, we have to use Avogadro's number and molar mass.
Avogadro's number: 6.022×10²³ atoms/mol
Molar Mass: 107.87 g/mol
Now that we have everything we need, we can convert atoms to grams.
