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.

Ans 1. Both

Ans 2. Once inside plants, carbon moves through food chains, where organisms become nutrients including herbivores, carnivores and ultimately, decomposers. Once buried in the soil, carbon can be converted into fossil fuels over long periods of time and then also reenter the atmosphere by combustion. The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law

Ans 3. Most of the chemical energy needed for life is stored in organic compounds as bonds between carbon atoms and other atoms. The law of conservation of energy states that energy can not be created or destroyed. Thus, just like matter energy is also conserved in the process.

Hope it helps

How many moles of calcium hydroxide, ca(oh)2, are needed to neutralize 2 moles of sulfuric acid, h2so4?
Ronch [10]
The balanced equation for the neutralisation reaction is as follows 
Ca(OH)₂ + H₂SO₄ ---> CaSO₄ + 2H₂O
stoichiometry of Ca(OH)₂ to H₂SO₄ is 1:1
equivalent number of acid reacts with base
number of H₂SO₄ mol reacting - 2 mol
according to molar ratio of 1:1
number of Ca(OH)₂ mol = number of H₂SO₄ moles 
therefore number of Ca(OH)₂ moles required - 2 mol

Rank the following from lowest to highest anticipated boiling point: C8H18, CH, C16H34,CH4,C4H10
viva [34]
<span>The relative strength of intermolecular forces such as ionic, hydrogen bonding, dipole-dipole interaction and Vander Waals dispersion force affects the boiling point of a compound. For this case, the longer the chain the higher the boiling point. 

</span>CH, CH4, C4H10, C8H18, C16H34

Hope this answers the question. Have a nice day.

Consider the first-order reaction described by the equation At a certain temperature, the rate constant for this reaction is 5.8
zubka84 [21]

<u>Answer:</u> The half life of the reaction is 1190.7 seconds

<u>Explanation:</u>

The equation used to calculate rate constant from given half life for first order kinetics:

t_{1/2}=\frac{0.693}{k}

where,

k = rate constant of the reaction = 5.82\times 10^{-4}s^{-1}

t_{1/2} = half life of the reaction = ?

Putting values in above equation, we get:

t_{1/2}=\frac{0.693}{5.82\times 10^{-4}s^{-1}}=1190.7s

Hence, the half life of the reaction is 1190.7 seconds
