Answer:
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

what is the difference between cyclic compound and straight chain compound in hydrocarbons reaction
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.

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.
Which element is the most reactive?
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.
What state does a gas turn into if it reaches it freezing point?
O Solid
O Liquid
Gas
O None of the above
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.
when a candle burns both physical and chemical changes take place at identify these changes give another example of a familiar process in which both the chemical and physical changes takes place.
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.

Which is a characteristic of an atom?
Atoms are the largest unit of matter.
Atoms can be seen by the naked eye.
Atoms come in different varieties.
Atoms are created in the Earth’s core.
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.
is it possible to convert molecule to molecule?
Answer:

What happens to the molecules of Nitrogen as it goes through deposition?
How many molecules are there in 3.00
moes of NH₃
Now
No of molecules:
[tex]\\ \sf\longrightarrow No\:of\;moles\times Avagdro\:no)[/tex]
[tex]\\ \sf\longrightarrow 3(6.022\times 10^{23})[/tex]
[tex]\\ \sf\longrightarrow 18.066\times 10^{23}[/tex]
[tex]\\ \sf\longrightarrow 1.8066\times 10^{22} molecules [/tex]
Calculate the volume of an object with a density of .85 g/mL and a mass of 212 g.
[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]

A chunk of sulfur has a volume of 8.33 cm3. What is the mass of this sulfur? (Density of sulfur = 2.07 g/cm3.)
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

What did Fermi mean when he said, "The reaction is self-sustaining"?
The reaction reached critical mass.
A spontaneous chain reaction had been accomplished.
The nuclear reaction was out of control.
The nuclear reaction could be controlled and maintained.
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
