A scientist proposes that an iron bar be divided into smaller and smaller pieces it is right to infer that during this process, the process produces, the smallest piece of the iron (Option A)

<h3>What is Iron?</h3>

Iron has the chemical symbol Fe and the atomic number 26. It is a metal from the periodic table's first transition series and group 8. It is the most common element on Earth by mass, just ahead of oxygen, and makes up much of the Earth's outer and inner core.

Alloy steels, such as carbon steels, are made using iron plus additions such as nickel, chromium, vanadium, tungsten, and manganese. Bridges, power pylons, bicycle gears, cutting tools, and rifle barrels are all made from them. Carbon content in cast iron ranges from 3-5%. It is utilized in the manufacture of pipes, valves, and pumps.

Which is the IUPAC name for NO?
Vanyuwa [196]

Answer:

Nitrogen (ii) oxide

Explanation:

To know the IUPAC name for NO, we shall determine the oxidation number of N in NO.

NOTE: The oxidation number of oxygen (O) is always – 2.

Thus the oxidation number of N in NO can be obtained as follow:

N + O = 0 (ground state)

N + (– 2) = 0

N – 2 = 0

Collect like terms

N = 0 + 2

N = +2

Thus, the oxidation number of Nitrogen (N) in NO is +2.

Therefore, the IUPAC name for NO is Nitrogen (ii) oxide

(c) Polar solutes were separated by hydrophilic interaction chromatography (HILIC) with a strongly polar bonded phase. How would
Lelu [443]

Answer:

(c) The retention time would be higher (d) The retention time would be lower.

Explanation:

For the polar solutes which were separated using the hydrophilic interaction chromatography (HILIC) with a strongly polar bonded phase, the retention time would be higher if eluent were changed from 80 vol% to 90 vol% acetonitrile in water.

However, for the polar solutes which were separated using the normal-phase chromatography on bare silica with methyl t=butyl ether and 2-propanol solvent, the retention time would be lower if the eluent were changed from 40 vol% to 60 vol% 2-propanol.

Archy [21]

<u>Answer:</u>

<em>The system is the Answer </em>

<em></em>

<u>Explanation:</u>

System is the region which is taken into consideration.

While we perform a chemical reaction the system is the substance taken in the container.

So, A thermodynamic system is the amount of matter or the region in universe which is under the study.

The region outside the beaker are called as surroundings.

The beaker (the surface which separates the system from its surroundings) is said to be the boundary

System + surroundings = universe
