hello please help:) thank you!

Answer:

its atomic number

Explanation:

which is defined as the number of units of positive charge (protons) in the nucleus. For example, if an atom has a Z of 6, it is carbon, while a Z of 92 corresponds to uranium.

Chromium exhibits a wide range of possible oxidation states, where the +3 state is the most stable energetically. The +3 and +6 states are the most commonly observed in chromium compounds, whereas the +1, +4 and +5 states are rare.

Answer:

Cesium

Explanation:

Cesium is second from the bottom of this group, has 6 shells of electrons, and it matches the features of a reactive atom, making it the most reactive element.

Answer:

35.3052 grams of zinc are there in 0.54 mol of zn.

Answer:

I think it s the third one

BTW yw if it's correct

Answer:

So, the melting of wax and vapourisation of melted wax are physical changes. Chemical Changes : The wax near flame burns and gives new substances like carbon dioxide, carbon soot, water vapour, heat and light. LPG is another example of a familiar process in which both the chemical and physical changes take place.

 A Chart Of The Chemical Elements That Displays Them In Rows Horizontally In Order Of Increasing Atomic Number And Vertically According To Similarity Of The Chemical Properties Of Their Atoms.

[tex]\\ \sf\longmapsto Volume=\dfrac{Mass}{Density}[/tex]

[tex]\\ \sf\longmapsto Volume=\dfrac{212}{0.85}[/tex]

[tex]\\ \sf\longmapsto Volume=249.4mL[/tex]

Answer:

[tex]249.41 \: ml[/tex]

Explanation:

[tex]volume = \frac{mass}{density} \\ = \frac{212g}{0.85 \: g \: {ml}^{ - 1} } \\ = 249.41 \: ml[/tex]

Hope this helps you.

Let me know if you have any other questions :-):-)

Answer:

The nuclear reaction could be controlled and maintained.

Explanation:

People had initiated a self-sustaining nuclear reaction--and then stopped it. He had released the energy of the atom's nucleus and controlled that energy.

Fermi's achievement in setting off the first self-sustaining nuclear chain reaction from his design of an atomic pile led to a new Age of the Atom. The controlled release of nuclear energy was now a reality

Due to the fact that electrons are delocalized in graphite, it is a good conductor of electricity. Carbon atoms in graphite form hexagonal layers and are in covalent bonds with three other carbon atoms. Due to this non-bond electron configuration, each carbon atom conducts electricity in the form of a delocalized electron.

Explanation:

Cyclic Hydrocarbons

A cyclic hydrocarbon is a hydrocarbon in which the carbon chain joins to itself in a ring. A cycloalkane is a cyclic hydrocarbon in which all of the carbon-carbon bonds are single bonds. Like other alkanes, cycloalkanes are saturated compounds. Cycloalkanes have the general formula CnH2nCnH2n. The simplest cycloalkane is cyclopropane, a three-carbon ring.

Answer:

Solid

Explanation:

According to Wikipedia

Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.

Explanation:

equations to note:

density= mass/volume

mass= volume *density

volume= mass/density

you have a volume- 8.33cm3

you have a density- 2.07 g/cm3

Answer:

8.33cm3 * 2.07g/cm3=  17.24g

mass= 17.24g
