Statements that describes nuclear fission and nuclear fusion as regards this question are:
C: They both release large amounts of energy
D:They both involve one atom splitting into two atoms.
Both fission and fusion can be regarded as nuclear reactions that brings about production of energy. However they have different applications.Fission can be explained as the splitting of a heavy as well as unstable nucleus into two nuclei , but this nuclei are lighter compare to the mother nucleus.
Fusion on the other hand can be regarded as a process involving two light nuclei coming together to form one and then release vast amounts of energyFor instance, uranium will undergo fission to produce strontium and krypton nuclei
Therefore, option C, D are right.

Explain why it was important for scientists to have a standard system of naming compounds and other chemical procedures.
It is important for scientists to have a standard system of naming compounds and other chemical procedures to avoid ambiguity in the nomenclature of chemical compounds and procedures.
Chemicals may be referred to by various names among various scientists in different places. These different names creates confusion when scientists present their discoveries to other scientists outside their locality.
Therefore, it is imperative that a unified and standard system of nomenclature should be devised so that all scientists can have the same name for compounds. This reduces ambiguity associated with the nomenclature of chemical substances and procedure.

Group of answer choices
plotting celestial objects on a graph
creating maps of the sky by dividing the celestial sphere into 88 different areas
creating geographic maps of continents and countries
planning the route that planes will fly in the sky
Explanation:
creating geographic maps of continents and countries
Jonah is filling out paperwork for insurance and in the “applicant occupation” space he writes cartographer so, his job is creating geographic maps of continents and countries, hence option C is correct.
Who is cartographer ?A person who draw and produce a map is a cartographer. Cartography is the art and science of graphically representing a geographical area, usually on a flat surface such as a map or chart.
This may involve the superimposition of political, cultural, or other nongeographical divisions onto the representation of a geographical area.
A person whose work is making maps or charts is a cartographer. An example of a cartographer is Claudius Ptolemy and his book Geographica . Anaximander was the first ancient Greeks to draw the map of known world.
Hence, cartographer creates the geographical maps.

#1. Boyle's Law. A gas with a volume of 4.0 L at a pressure of 205 kPa is allowed to expand to a volume of 12.0 L.
What is the pressure in the container if the temperature remains constant? (Answer is 68.3 kPa).
Explanation:
According to Boyles law[tex]pressure \: \alpha \frac{1}{volume} [/tex]
P1V1 = P2V2
205 (4) = P2 (12)
[tex]P2 = \frac{205 \times 4}{12} [/tex]
P2= 820/12
P2= 68.3 KPa
The pressure in the container after the expanssion of gas, if the temperature remains constant is 68.3 kPa.
What is Boyle's Law?According to the Boyle's Law, at constant temperature pressure of any gas is inversely proportional to the volume of the gas, i.e.
P ∝ 1/V
Required equation for the calculation of the pressure is:
P₁V₁ = P₂V₂, where
P₁ = initial pressure = 205 kPa
V₁ = initial volume = 4 L
P₂ = final pressure = ?
V₂ = final volume = 12 L
On putting all these values on the above equation, we get
P₂ = (205)(4) / (12) = 68.3 kPa
Hence resultant pressure is 68.3 kPa.

A.) Solid
B.)gas
C.)liquid
Answer:
solid
Explanation:
because solid has a definite shape and volume
Answer:
Liquid
Explanation:
This is because the intermolecular forces of attraction are strong enough to hold the molecules together but not so strong as to fix them into definite positions (as in solids). Instead, they possess fluidity and hence no definite shape.
Why do you sound weird when you hold your your nose and talk?
Answer:
People with a nasal voice can sound as though they're speaking through a clogged-up or runny nose, which are both possible causes. Your speaking voice is created when air leaves your lungs and flows upward through your vocal cords and throat into your mouth. The resulting sound quality is called resonance. (i hope i helped ya )
Explanation:
How many moles of HCl can be produced from 0.207 g of SOC12 SOC12(1) + H2O(1) = SO2(g)+ 2HCl(g)
Answer:
.80*10⁻³ moles of HCl can be produced from 0.226 g of SOCl₂
Explanation:
The balanced reaction is:
SOCl₂ + H₂O ----> SO₂ + 2 HCl
By stoichiometry of the reaction they react and produce:
SOCl₂: 1 mole
H₂O: 1 mole
SO₂: 1 mole
HCl: 2 mole
Being:
S: 32 g/mole
O: 16 g/mole
Cl: 35.45 g/mole
H: 1 g/mole
the molar mass of the compounds participating in the reaction is:
SOCl₂: 32 g/mole + 16 g/mole + 2*35.45 g/mole= 118.9 g/mole
H₂O: 2*1 g/mole + 16 g/mole= 18 g/mole
SO₂: 32 g/mole + 2*16 g/mole= 64 g/mole
HCl: 1 g/mole + 35.45 g/mole= 36.45 g/mole
Then, by stoichiometry of the reaction, the following amounts of mass react and are produced:
SOCl₂: 1 mole* 118.9 g/mole= 118.9 g
H₂O: 1 mole* 18 g/mole= 18 g
SO₂: 1 mole* 64 g/mole= 64 g
HCl: 2 mole* 36.45 g/mole= 72.9 g
Then the following rule of three can be applied: if by stoichiometry of the reaction 118.9 grams of SOCl₂ produce 2 moles of HCl, 0.226 grams of SOCl₂ how many moles of HCl do they produce?
moles of HCl= 3.80*10⁻³
3.80*10⁻³ moles of HCl can be produced from 0.226 g of SOCl₂

Hurricane-force winds spread the firestorm; trees became
blowtorches, sucking fire from the ground and hurling it in

The Great Fire of 1910 that burned through parts of North Idaho, western Montana, eastern Washington, and southeastern British Columbia serves as a model of conduction as the fire spread from tree to tree without actual movement of the trees away from their position but as a result of contact between the burning flames in the trees.
What are the processes of heat transfer?Heat transfer processes refers to the process by which heat energy is transferred from one point to another within a medium of between two points.
There are three processes of heat transfer, namely:
ConductionConvection, and RadiationConduction is a process of heat transfer in which is transferred from one point to another in a medium without the actual movement of the particles of that medium.
During conduction, the particles of the medium vibrate about a mean position as they acquire heat. This heat energy is then transferred from that particle to the neighboring particle as they particles are in close contact. Hence the heat is transferred from one particle to the next.
