Do consumers agree that extended range on a electric vehicle is a key feature they look for in an EV? Most companies are putting silicon as a key resource in order to accomplish this.

Consumers or customers? If you ask a average consumer as in someone who drives but is considering buying a car. Range will be a big key feature, more is better. If you as a customer who is an owner of an EV the

How is graphite used as a lubricant?

The structure of graphite consists of sheets. There are hexagonal carbon rigs attached to one another to form sheets while these individual sheets are held together by van Der Waal forces. Hence when subjected to any external force thsee van Der waal forces are overcome and the sheets slide on one another, therefore making graphite a useful lubricant.

It has a lower density as a solid than as a liquid.It is one of the few substances to exist in all three phases on this planet.It is one of the imperative basic chemicals of life.Its density is

What chemical elements make up light?

Chemistry is about the interactions between atoms and molecules. They interact with the electromagnetic force, and light is an electromagnetic wave of only a limited spectrum.

What is the best way to easily understand chemistry?

I firmly beleive that, motivation generates interest and vice versa.  Chemistry is an experimental science, we see a lot of examples in our daily life that involve chemistry. You just need someone to point that out or find out on

Why is the sun burning without the presence of oxygen in our space?

Oxygen is involved in normal combustion, but the Sun is not burning nor combusting.The Sun is not burning.The Sun derives its energy from the atomic fusion of hydrogen into helium. That process releases so much energy, it travels to the surface of the Sun and radiates in all directions.

What would happen if all the carbon dioxide suddenly vanished?

Photosynthesis won't take place from that day onwards. We the human beings depend upon heterotrophic mode of nutrition to survive. Plants are the primary sources of food. Think about a condition where the primary food sources are no more.This affects the whole food chain. As a result,human race too will be wiped off

What happened to the hydrogen economy?

It may never happen. Hydrogen is a storage medium. There are no sources (on Earth) of hydrogen that is not compounded with some other element, such as water, H2O, or methane, CH4.It takes energy to separate the hydrogen from the compound. Quite a lot of energy if you are starting

Why is carbon a source of energy?

While carbon alone is a good source of energy--anthracite coal is a good example--carbon also has an amazing ability to bond with hydrogen and form hydrocarbons. Fossil fuels like coal and petroleum are chock full of hydrocarbons. Ancient algae and plant life stored solar energy through photosynthesis in the atomic bonds between hydrogen and carbon, and then

How does using helium deplete the helium in our atmosphere?

As others have written, using helium for balloons and other purposes doesn't deplete it from our atmosphere since it isn't concentrated enough in the atmosphere to be economically separated. It's relative concentration in the lower 100 Km of the atmosphere where

What happens to water when melting?

The loose, stable and long-term regular crystal structure of ice, held by hydrogen bonds, collapses. The disordered structure of the liquid water is more dense than that of the solid state. The liquid water however is not totally disordered. Short-living short-distance regular structures keep forming and collapsing it it.

How do we know that our sun will run out of its hydrogen fuel in 5.5 billion years?

The eggheads have models of fusion processes and the astronomers can look out and see lots of stars in various stages of their lives, so by some clever observation and theory swirled together, they can come up with that 5.5 billion year number.    Not that any of us will be around then.

Is there any relation between atomic vibration and atoms in excited or ground state?

I'm going to assume you mean molecular vibrations because single atoms don't vibrate unless we're talking about lattice modes or something. Anyway, there is no guarantee that the vibrations in the ground state of a molecule will be the same

Does a light molecule have mass?

Ok, first off... light is not made up of molecules so there is nothing like a

Have scientists discovered all the elements?

No, they do not. Theoretical physicists have been working with models related to something called

Why isn't the water molecule linear?

The shape of molecules is determined by the relative energies of the possible shapes and this in turn is determined by the electron configuration and the size of the molecules components. The shape is that which minimises the energy. One complication is that

Why does fire need oxygen?

Hi, I think the answer you are looking for is why oxygen allows combustion (heat exchange). It's its lone pair of electrons which allow easily for the chemical reaction that started the fire to continue its spread.Take another highly combustible atom, nitrogen

How much liquid nitrogen would it take to cool Venus to 78 degrees Fahrenheit?

Very difficult math for me. I would use the equation Q = m cp DTThe Q stands for the heat m for the massCp is the specific heatDT is the temperature difference. For example if you want to boil water from 25 degrees centigrades to 100, the difference is 75. In the case of

In which form is oxygen stable?

In diatomic form that is O2 ...Oxygen atom has 8 electrons from which 2 are unpaired in orbitals (2py and 2pz orbitals) and making them paired by two covalent bonds with another oxygen atom completes the octate this is why the diatomic form is stable.

Can we feed the sun hydrogen to prevent it from burning out?

Sure you can. Go right ahead. All you have to do is to figure out where there is enough to make a difference and how you will move it to the sun. The sun will "burn" for a few more billion years so you won't be

What do most people get wrong about basic chemistry?

Its not just chemistry it's the entire process. I had a friend tell me that if all the best chemists got together with an unlimited budget they could cure cancer in a week. I've heard that and similar statements many times on my Facebook. Its wrong it's so wrong it's not even

How to make oxygen

What tools and materials do you have? Either wait for a plant or batch of Cyanobacteria to make you some through photosynthesis, or you can split water into hydrogen and oxygen with electrolysis, but it's prohibitively expensive.

Why is nitrogen important to organism?

DNA replication is required for cell division. But making new DNA means it will require components of which it is made up of like nitrogenous bases like adenine, guanine, cytosine and thymine.Again protein is made up of amino acids which are further made up NH2 groups.So in short, nitrogen is really

What happens when you add more water to sugar water?

If sugar water is cold at 4 degree centigrade and you add further water of 4 degree centigrade then the sugar water will remain as it is.If sugar water is cold and if you add water of any other temperature then the sugar water will be less sweet.If sugar water
