starting with 500.4 of glucose, what is the maximum amount of ethanol in grams and i'm liters that can be obtained by this process( density of ethanol=0.789 g/mL

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

Answer:

1027.9 mL, its easy

Explanation:

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.

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.

[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 :-):-)

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:

1)A moth bursting out of a cocoon is neither a chemical or physical change, it's a biological change.  If I had to chose it would be a physical change though.  Not to sure...

2)Playing with slime is a physical change.  

Explanation:

1)The reason why I would chose physical change is because the moth is changing it's physical state more than it's chemical composition, but you should say both if that's an option.  

2)A physical change is when the temperature, shape, or state of matter changes. A chemical change occurs when the actual substance changes.  An example of this is a chemical reaction.  Because the slime is changing shape and not substances, I would say that it's obviously a physical change.  

Hope this helps, sorry that I'm not too sure about the 1st question.  

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.

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.

Answer:

Plant food is the sugars created via photosynthesis. The sugar created is glucose which can be used by the plant for energy and also to make other things like starch and cellulose.

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.

Answer:

yes, it's possible to covert molecule to molecule

Explanation:

Converting between molecules and moles is done by either multiplying by or dividing by Avogadro's number.

Answer:

what the model is describing is the molecules. when molecules are tightly packed they form a solid like ice, and when the ice is melting forms a liquid because the molecules are spreading out. when the ice evaporates (gas) the molecules are moving about and are not touching eachother

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:

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
