Questions to be ask for testing a starch

I'm assuming you're asking how to test for a starch,


To do so you do this thing called the "Iodine Test"
The potassium iodide aqueous solution will form this complex with starch to form a purplish-blue color.

However, watch out for the pH as hydrolysis of starch could occur to prevent the test from working out-- and the temperature as the greater it is, the less intense the color is

Amobarbital sodium react with ethanolic sodium hyrooxide
CaHeK987 [17]

Amobarbital (like all barbiturates) works by being incontestible to the GABAA receptor at either the alpha or the beta subunit.

<h3>What is the mechanism of amobarbital?</h3>

Amobarbital (like all barbiturates) works by binding to the GABAA receptor at either the alpha or the beta subunit. These are compulsory sites that are distinct from GABA itself and also distinct from the benzodiazepine binding site.

Amobarbital is a barbiturate classified as having a halfway duration of action, meaning that the effects of the drug can last from 4-6 amobarbital increases the effects of benazepril by apparatus: pharmacodynamic synergism.

So we can conclude that Amobarbital, 5-ethyl-5-isoamyl barbituric acid like all barbiturates.

Which particle may be gained, lost, or shared by an atom when it forms a chemical bond?
andrew-mc [135]

Electrons because the amount of valence electrons determines the bonds it can form and often times during a chemical bond or the forming of a compound an element will lose some of its electrons.

Refer to the Chemical Compounds table above. How many total elements are in<br> Ethanol?
Korolek [52]

Answer:

3 element i.e carbon (C), hydrogen (H) and oxygen.

Explanation:

The following data were obtained from the question:

Subtance >>>>>>>> Chemical Formula

Glucose >>>>>>>>> C₆H₁₂O₆

Methane >>>>>>>> CH₄

Ethanol >>>>>>>>> C₂H₅OH

Hydrogen peroxide >> H₂O₂

From the above table, we can see that ethanol (C₂H₅OH) contains carbon (C), hydrogen (H) and oxygen

Therefore, the total number of elements present in ethanol, C₂H₅OH is 3.

Read the false statement. Atoms of elements with one valence electron form anions in order to meet the octet rule. Which answer
Zepler [3.9K]

Answer:

C. Atoms of elements with five to seven valence electrons form anions in order to meet the octet rule.

Explanation:

  • Atoms of elements gain or lose electron(s) to obey the octet rule by forming cations or anions.
  • Atoms with 1 to 3 valence electrons lose electrons to form cations in order to attain a stable configuration.
  • Atoms with 5 to 7 valence electrons gain electron(s) to form anions in order to attain stable configuration.
  • However, atoms with 8 valence electrons do not require to gain or lose electrons since they an octet configuration.
  • Atoms of metallic elements such as those in group 1 and 2 lose electron(s) to form cations while atoms of non-metallic elements such as halogens require to gain electron(s) to form anions so as to obey the octet rule.
