The cell wall is the outer most covering of the cell. The cell wall covers the cell membrane. The cell membrane is also known as the plasma membrane or plasma lemma. There is no other name for the cell wall. The cell membrane is present in almost all types of cells. The cell wall is present in bacteria, fungi, algae and plant cell. It is absent in an animal cell and protozoa. The cell membrane is a biological membrane, which is semi- permeable. It allows the passage of certain substances through them.

Describe the smell of Na+ and H+

KIM [24]

Answer:

Sodium ion ( Na+) is known to have no smell at all but however appears salty which is the reason why the compound Sodium Chloride has the same type of taste.

Hydrogen ions ( H+) are known to have no taste which implies it being tasteless. It is also important to note that it has no smell too when perceived (odorless).

When 500.0 g of water is decomposed by electrolysis and the yield of hydrogen is only 75.3%, how much hydrogen chloride can be m

Evgen [1.6K]

The amount of hydrogen chloride that can be made is 1064 g

Why?

The two reactions are:

2H₂O → 2H₂ + O₂ 75.3 % yield

H₂ + Cl₂ → 2HCl 69.8% yield

We have to apply a big conversion factor to go from grams of water (The limiting reactant), to grams of HCl, the final product. We have to be very careful with the coefficients and percentage yields!

$500.0gH_2O*\frac{1moleH_2O}{18.01 gH_2O}*\frac{2 moles H_2}{2 moles H_2O}*\frac{2.015g H_2}{1 mole H_2}*\frac{75.3 actual g}{100 theoretical g}=42.12 g H_2$
