A = Smooth Endoplasmic Reticulum
B = Vacuole
C = Mitochondria (Plural)
D = Nucleolus
E = Cell Wall
Explanation:
This is obviously a plant cell. Animal cells do not have cell walls(E), and most animal cells will not have a vacuole(B). Smooth Endoplasmic Reticulum: This produces protiens (contains ribosomes) but when looked through a microscope, will appear to be smooth. The vacuole(B) is like a storage for the plant cell, and it helps support the plant cell. This is the reason why plants “droop” when you don’t water them for a long time. Mitochondia (Plural) processes nutrients for the cell. The nucleolus(D) covers the nucleus. It’s main function is to process RNA and combine it with proteins. The cell wall(E) helps support and protect the cell.
367.2 g of silver
Explanation:
To find the mass of a substance knowing the number of moles we use the following formula:
number of mole = mass / molecular weight
In the case of silver we use the atomic weight of 108 g/mole.
mass = number of moles × molecular weight
mass of silver = 3.4 moles × 108 g/mole
mass of silver = 367.2 g

good luck on whatever this is for my dude.
The kidneys will excrete increased quantities of acid.
Explanation:
The kidneys will excrete excess H+ ions in the blood (remember H+ ions are responsible for acidity) until the acid-base balance is restored in the blood. Bicarbonates, on the other hand, will be aggressively reabsorbed by the renal tubules as the excess H+ are being excreted.
The acid base balance is mainly determined by the quantities of H⁺ and HCO₃⁻ ions in teh blood. These ions come from the dissociation of carbonic acid formed when carbon dioxide from tissues is dissolved in blood plasma.
