Compare and contrast cytokines in animal and plant cells
GarryVolchara [31]
<h3>Answer:</h3>

Cytokinesis in animal cells occur by cleavage while in plants it occurs through the formation of a cell plate.  

<h3>Explanation:</h3>
  • Cytokinesis refers to the process through which the cytoplasm divide in animal and plant cells.
  • It occurs after the division of the nucleus.
  • Cytokinesis in animal cells differs from that in plant cells in that, in animal cells it occurs by cleavage while in plant cells cytokinesis occurs through the formation of a cell plate.
  • In animal cells, cleavage occurs as a result of the activity of actin and myosin which results to dividing of cytoplasm in to two.
  • In plant cells, cell plate is formed by the fusion of golgi bodies on the equator which will generate cell wall and the plasma membrane between daughter cells.

A dehydration reaction starting with 3.8 g cyclohexanol produces 2.6 g cyclohexene. Calculate the theoretical yield for this rea
diamong [38]

Answer:

Theoretical yield of C6H10 = 3.2 g.

Explanation:

Defining Theoretical yield as the quantity of product obtained from the complete conversion of the limiting reactant in a chemical reaction. It can be expressed as grams or moles.

Equation of the reaction

C6H11OH --> C6H10 + H2O

Moles of C6H11OH:

Molar mass of C6H110H = (12*6) + (1*12) + 16

= 100 g/mol

Mass of C6H10 = 3.8 g

number of moles = mass/molar mass

=3.8/100

= 0.038 mol.

Using stoichoimetry, 1 moles of C6H110H was dehydrated to form 1 mole of C6H10 and 1 mole of water.

Therefore, 0.038 moles of C6H10 was produced.

Mass of C6H10 = molar mass * number of moles

Molar mass of C6H10 = (12*6) + (1*10)

= 82 g/mol.

Mass = 82 * 0.038

= 3.116 g of C6H10.

Theoretical yield of C6H10 = 3.2 g

a compound is found to contain 31.1% sulfur and 68.9% chlorine determine the empirical formula for the sulfur and chlorine sampl
ollegr [7]

Answer:

Empirical formula = S₁Cl₂ = SCl₂

Explanation:

The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound.

This compound contains 31.1% sulfur and 68.9% chlorine.

That is 100g of the compound contains 31.1 g of sulfur and 68.9 g of chlorine.

Convert the mass of each element to moles using the molar mass from the periodic table.

Moles of Sulfur = \frac{31.1}{32.065 } \\

= 0.9699

Moles of Chlorine= \frac{68.9}{35.453 } \\

= 1.9434

Divide each mole value by the smallest number of moles calculated.

Units of sulfur =  \frac{0.9699}{0.9699} \\

= 1

Units of Chlorine =  \frac{1.9434}{0.9699} \\

= 2

Empirical formula = S₁Cl₂ = SCl₂
