Definition for starch in science ?

Chemistry
1 answer:
Akimi4 [234]3 years ago
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.

Why does a high temperature have to be used to weld pieces of metal together
bazaltina [42]

because of the metling point of metals, it is difficult to just simply put metal together and have them to stay together without any type of glue or epoxy based creams.

wielding is used to melt the surface or even change the compound completely so they are able to combine with other metals.

same thing with atoms, you need a lot of heat, and speed to simply make salt or even copper because of the elements not really being favorable of each other.

For the reaction below, which change would cause the equilibrium to shift to the right? EXPLAIN.
Mice21 [21]

Answer:

C. Decrease the concentration of hydrogen gas

Explanation:

<u><em>Decreasing the concentration of hydrogen gas</em></u><em> would cause the equilibrium to shift to the right.</em>

According to Le Chatelier's principle, when a reaction is in equilibrium and one of the constraints affecting reactions is varied, the equilibrium will shift so as to annul the effects of the change.

Decreasing the concentration of dihydrogen sulfide will cause the equilibrium to shift to the left because as reactants are removed, more of the reactants would be formed.

Increasing the pressure of the system will also cause the equilibrium to shift to the left because the total number of moles of reactants is less than that of products. Hence, more of reactants would be formed with increased pressure.

Increasing the concentration of carbon disulfide will cause the equilibrium to shift to the left because as more of the products are added into the reaction, more of the reactants will begin to form.

<u>The only reason for the equilibrium to shift to the right causing more of the products to be formed is decreasing the concentration of hydrogen gas which happens to be one of the products. As more of the products are removed from the reaction, the equilibrium will shift to ensure that more products are formed.</u>

The correct option is C.

9.31g is the same mass as ?
Dmitry_Shevchenko [17]

Answer:

9.31 g = 0.00931 kg

Explanation:

We need to tell that 9.31 gram is same as what. There are many units that measure the meass of an object like milligram, kilogram, centigram etc.

The relation between kilogram and gram is as follows :

1 kg = 1000 g

or

1 g = 0.001 kg

If we change 9.31 gram to kg, we get :

9.31 g = (9.31 × 0.001) kg

or

9.31\ g=9.31\times 10^{-3}\ kg\\\\=0.00931\ kg

Hence, 9.31 g is the same mass as 0.00931 kg.
