Answer:
A salt bridge refers to a device used to form an electrochemical cell by providing a means to support the free flow of ions between the oxidation and reduction half-cell components. A salt bridge facilitates corrosion because corrosive reactions typically occur in the presence of electrochemical cells.

Answer:
What is the matrix used in lithography? Lithography is a planographic or "flat surface" method that uses a stone slab matrix. Unlike relief and intaglio printing, the matrix used in lithography is completely flat. Serigraphy is also known as "silkscreen painting".

Answer: 225.75g
Explanation:
Molar Mass of Fe(OH)2 = 56 + 2(16 + 1) = 56 + 2(17) = 56 + 34 = 90g/mol
1mole(90g) of Fe(OH)2 contained 6.02x10^23 units.
Therefore, Xg of Fe(OH)2 will contain 1.51x10^24 units
Xg of Fe(OH)2 = (90x1.51x10^24)/6.02x10^23 = 225.75g
Answer is: a suspension.
Suspension is a heterogeneous mixture (solute particles do not dissolve), that contains solid particles (for example nickel sulfide or NiS) sufficiently large for sedimentation.
The internal phase (solid nickel sulfide) is dispersed throughout the external phase (water).
Another example of a suspension is sand in water.
Answer:
Volume = 30cm³
Explanation:
A block is a geometrical figure and its volume, -look at the figure-, follows the equation:
Volume = Width*Length*Height
As the measurements of the block are 5.00cm, 3.00cm and 2.00cm, the volume is:
Volume = 5.00cm*2.00cm*3.00cm
<h3>Volume = 30cm³</h3>
