Convert 67.2 L CO at STP to moles

Chemistry
1 answer:
seropon [69]3 years ago
6 0

To Find :

The STP moles of 67.2 L CO.

Solution :

We know, molar volume at STP is used to converted into moles by :

1 moles = 22.4 L STP

So, number of moles in 67.2 L CO is :

n=\dfrac{67.2}{22.4}\\\\n = 3 \ moles

Therefore, number of STP moles are 3.

Hence, this is the required solution.

How could you test to see if an enzyme was completely saturated during an experiment?
rodikova [14]
To test this, you'd need to see if a reaction is still taking place, If the enzyme is completely depleted, then the reaction could no longer occur.

Alkenes are ______.<br><br> Saturated<br> Unreactive<br> Single bonds<br> Very reactive
Aleksandr [31]
Answer:
            Alkenes are <u>Very Reactive</u>.

Explanation:
                   Other options are incorrect because;

Saturated compounds are those hydrocarbons which contains only single bonds, while alkenes contain atleast one double bond.

Single bonds again stands for saturated compounds, hence it is false.

Alkene are reactive because the double bond has the potential to open by addition reaction. So electrophiles are readily added across double bond. This reactivity can also be explained by the exposure of nucleophilic double bond above and below the plane, which is highly exposed to incoming electrophiles.

Which type of relationship exists between Alaskan brown bears and salmon? A. predation B. mutualism C. competition D. commensali
aksik [14]

Answer:

A. predation.

Explanation:

Predation is a type of ecological interaction in which one organism which is known as predator feeds upon another organism thereby killing it. The organism which is killed by predator is known as prey. In such interaction one organism is benefited while another one is harmed.

Brown bears of Alaska feed upon salmon. In order to so they have developed many ways which include waiting at the bottom of falls from where salmons pass by or standing at the bottom of the falls.

Theory

Sea floor spreading

Subduction

Magnetic reversal

Convection current

Explanation:

A system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation

_____Theory___ - The process by which new oceanic lithosphere (sea floor) forms when magma rises to earth’s surface at mid-ocean ridges and solidifies, as older, existing sea floor moves away from the ridge

____Sea floor spreading___ - The process by which one lithosphere plate moves beneath another plate as a result of tectonic forces

__Subduction _ - The process by which earth’s magnetic north pole and magnetic south pole switch positions periodically, a change in the direction in which earth’s magnetic field points.

____Magnetic reversal _ - Any movement of matter that results from differences in density may e vertical circular or cyclical.___ Convection current___.

A theory is scientific postulates that explains a particular observation. Theories are products of careful scientific investigations that are made from a single hypothesis. They result from hypothesis that has been well tested, repeated and has been subjected to rigorous experimentation by other scientists.

At the divergent margin, the sea floor is spreading. This idea was brought into light around the mid twentieth century. New tools from the second world war were used to investigate the sea floor.

Records shows that as new magma upwells to the the surface, the older ones are forced back away from the margin. Younger rocks are found close to the margin whereas the old ones are far away from the margin.

Subduction occurs when a denser oceanic plate forces its way downward into the mantle because it is denser. The lighter plate either oceanic or continental rides on top of it. The region where this convergent type of plate motion occurs is called a subduction zone.

The geomagnetic field of the earth is produced as a result of the movement  of metallic minerals in the outer molten core. This produces the earth magnetic field that approximately has its north and south pole close to the geographic one. Sometimes the magnetic direction changes and it reverses. The N-S orientation alternates and this leads to a magnetic reversal.

Convection current is used to transfer energy especially heat based on the differences in density. This is usually between fluids i.e gas and water. The denser materials sinks and the light ones floats. The difference in density is attributed to temperature differences.
