5 0

Answer:

  1. Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. or
  2. Starch is a long-chain polymer of glucose molecules joined together. or
  3. A starch is a complex polysaccharide made up of a large number of glucose units joined together by glycosidic bonds.

Explanation:

starch, a white, granular, organic chemical that is produced by all green plants. Starch is a soft, white, tasteless powder that is insoluble in cold water, alcohol, or other solvents.

Starch is amongst the most abundant plant products and is a mixture of two polymers, amylose and amylopectin. During food processing starch is transformed by hydrothermal treatments. ... The structure of starch is also influenced by specific and non-specific interactions with other food constituents and ingredients.

When 5ml of HCl was added
777dan777 [17]

Answer:

A. There was still 140 ml of volume available for the reaction

Explanation:

According to Avogadro's law, we have that equal volumes of all gases  contains equal number of molecules

According to the ideal gas law, we have;

The pressure exerted by a gas, P = n·R·T/V

Where;

n = The number of moles

T = The temperature of the gas

R = The universal gas constant

V = The volume of the gas

Therefore, given that the volumes and number of moles of the removed air and added HCl are the same, the pressure and therefore, the volume available for the reaction will remain the same

There will still be the same volume available for the reaction.
