Answer:

1. Theoretical yield = 2.03g

2. Actual yield 1.89g

Explanation:

Let us write a balanced equation. This is illustrated below:

Zn + 2HCI —> ZnCl2 + H2

Molar Mass of HCl = 1 +35.5 = 36.5g/mol

Mass of HCl from the balanced equation = 2 x 36.5 = 73g

Molar Mass of H2 = 2x1 = 2g/mol

1. From the equation,

73g of HCl produced 2g of H2.

Therefore, 74g of HCl will produce = (74 x 2)/73 = 2.03g

Therefore, theoretical yield = 2.03g

2. %yield = 93%

Theoretical yield = 2.03g

Actual yield =?

%yield = Actual yield /Theoretical yield x100

Actual yield = %yield x theoretical yield

Actual yield = 93% x 2.03 = (93/100)x2.03 = 1.89g

Actual yield =1.89g

How are protists different from plants​
kotegsom [21]

Answer/ explanation :

Protist can be multicellular or unicellular organisms

Plants are all multicellular and also exhibit cellular differentiation.

Protist can be autotroph, heterotrophic or decomposer

Plants are only autotrophs because they manufacture their own food through photosynthesis

Protists are microscopic, more diverse and abundant in nature

Plants are big and complex in nature

Nuclear DNA strands in plants are of higher complexity than those of protist

Plants require oxygen for cellular respiration process unlike protist which can be aerobic and some other species facultative anaerobic

Plants only can reproduce asexually through bulbs and tubers as in yam, potatoes while protists reproduce either sexually through meiosis or asexually through simple cell division.
