Answer:

Starch is a viable indicator in the titration process because it turns deep dark blue when iodine is present in a solution. When starch is heated in water, decomposition occurs and beta-amylose is produced

In the titration process, starch is a viable indicator because when iodine is present in a solution, it turns deep dark blue. Decomposition happens when starch is heated in water, and beta-amylose is formed.

Which series of atomic numbers represents the ordering of consecutive elements within the periodic table?

statuscvo [17]

Atomic number is same as the number of protons in the element which is further equal to the number of electrons. As the number of electrons increases in the element, the atomic number of the element also increases.

In periodic table, elements are arranged in the groups, and these groups are columns starting from 1 to 18, elements are arranged in increasing order of atomic number. Elements are placed with difference of one atomic number.

First four elements present in the periodic table is:

$He$ atomic number is one (1).

$H$ atomic number is two (2).

$Li$ atomic number is three (3).

$Be$ atomic number is four (4).

Thus, the series of atomic numbers that represents the ordering of consecutive elements within the periodic table is the last option - 1, 2, 3, 4...

Why is an alloy is often more useful than a pure metal

mrs_skeptik [129]

<h2>Answer:</h2>

A pure metal has specific properties. Sometimes we need that metal but with modified properties. So for the modification of properties we make alloys.

<h3>Explanation;</h3>

An alloy is a mixture of two elements, one of which is a metal.
Alloys often have properties that are different to the metals they contain.
This makes them more useful than the pure metals alone.
For example, alloys are often harder than the metal they contain.

Why is studying light and electrons important for chemistry and understanding the universe?

Brut [27]

Explanation :

The study of light and electrons are important for chemistry & universe.

As we know, everything is made up of particles even light & universe also. The particles are made of atoms and that atoms are made up of electrons, protons & neutrons.

An electron is one of the most important type of subatomic particles. Electrons combine with the proton to form atom. These electrons, protons & neutrons play a vital role in chemistry and universe.

The importance of an electron is that when two atoms react with each other or approach each other, their outermost shells come into contact first and these outermost shells electrons are involved in the chemical reaction.

Also important for chemical reactions, creating bonds, for electricity and the understanding of electrons has allowed for the better understanding of some forces which are in our universe such as electromagnetic force.

We know that the light is act as particle nature and it is a part of universe. As we know that chemists are only responsible for the chemical's study. Chemists cannot study the whole universe that is why they study light and the light is important because nothing would be able to survive.

The studying of light is important for the photoelectric effect, absorption, bio-molecules synthesis, vitamin D synthesis, vision, colors, drying & evaporation, sterilization, solar energy, spectroscopy, signal system and also for electron excitation.
