Using subject academic vocabulary (ex. Pretend you are teaching a friend about the differences between plant and animals cells.

Your friend isn’t even sure they know there is a difference between the types of cells.) write a narrative of what you would say to your friend to explain how the plant and animal cells are different from each other and why these differences are important.

The difference between the plant and animal cells is in their structures, and this makes their functions to differ. Some organelles are present in the plant cell which are absent in the animal cell and vice versa. The presence/absence of these organelles impact the kind of functions that can be carried out by each cell.

  • The plant cell has a rigid cell wall made of polysaccharides while the animal cell lacks cell wall. The cell wall serves supportive functions in the plant and gives it a shape. Animal cells are more or less round in shape.
  • Plant cells have chloroplasts while it is absent in the animal cell. the chloroplast contains chlorophyll, a green pigment that is responsible to absorbing radiant energy, As such, the chloroplast enables plant cells to carry out photosynthesis. Animals cells cannot synthesize their own foods.
  • Plant cells have large central vacuole that stores water and other contents while animal cells have small vacuole
  • Animal cells have centrioles while plant cells do not. The centrioles make mitotic division different between the two cells, although, the same result is obtained at the end of the day.

The following thermochemical equation is for the reaction of sodium(s) with water(l) to form sodium hydroxide(aq) and hydrogen(g
ra1l [238]

Answer:

1) When 6.97 grams of sodium(s) react with excess water(l), 56.0 kJ of energy are evolved.

2) When 10.4 grams of carbon monoxide(g) react with excess water(l), 1.04 kJ of energy are absorbed.

Explanation:

1) The following thermochemical equation is for the reaction of sodium(s) with water(l) to form sodium hydroxide(aq) and hydrogen(g).

2 Na(s) + 2H₂O(l) ⇒ 2NaOH(aq) + H₂(g) ΔH = -369 kJ

The enthalpy of the reaction is negative, which means that 369 kJ of energy are evolved per 2 moles of sodium. The energy evolved for 6.97 g of Na (molar mass 22.98 g/mol) is:

6.97g.\frac{1mol}{22.98g} .\frac{-369kJ}{2mol} =-56.0kJ

2) The following thermochemical equation is for the reaction of carbon monoxide(g) with water(l) to form carbon dioxide(g) and hydrogen(g).

CO(g) + H₂O(l) ⇒ CO₂(g) + H₂(g)  ΔH = 2.80 kJ

The enthalpy of the reaction is positive, which means that 2.80 kJ of energy are absorbed per mole of carbon monoxide. The energy evolved for 10.4 g of CO (molar mass 28.01 g/mol) is:

10.4g.\frac{1mol}{28.01g} .\frac{2.80kJ}{mol} =1.04kJ
