Why cant you get tin out of tin ore?
because you need heat to combine the compounds together
If 30.86g of H2O is frozen (from liquid to solid) how much heat energy is required?
No heat (energy) is required to freeze water (from liquid to solid). Freezing RELEASES energy (heat), as it is an exothermic event. If you want to know how much energy is release, you need to know the heat of fusion for water, and then multiply that by the mass of water being frozen.
Which equipment would help you separate a liquid mixture by distillation a freezer sand or gravel two flasks a heat source and a condensing tube a sieve such as a colander or kitchen strainer?
You need a heat source, a condensing tube and flasks.
Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
Is it necessary that compounds be colored to be separated by chromatography?
No, a compound doesn't need to be colored to be separated by chromatography. There are plenty of detectors that can be used outside of the visible spectrum, and in fact don't even use spectroscopic methods, such as Electron Capture detection (ECD).
How do you separate the carbon element and oxygen in carbon dioxide?
Carbon is solid (black powder, grey graphite or brilliant diamond) and methane is a (very light, explosive) gas. There is no need to separate, they alredy are! and do NOT dissolve in each other, so they'll stay separated as well.

Do you need a license to buy a heat pump?
I do not know of any jurisdiction in which a license would be required for a heat pump.
How do you separate mixture using heat?
Heat causes various elements to change their form, so when heating up a mixture you can cause the elements separate and isolate the element you are looking for.
Is it difficult to separate compounds and mixtures?
A compound can be separated from a mixture without being chemically altered; the separation of elements from a compound need chemical reactions.
How is the heat energy required to warm the body?
I really don't know but I think I need that answer for something!
What size furnace do you need for a 1700 sq ft home in Regina Sk?
You cannot accurately determine what size furnace is required based on the total square feet of a given space or structure. To accurately determine how much heat is required to heat your, you would need to have a Manual J Heat Load Calculation performed.
Why does evaporation need the sun in order for it to occur?
It doesn't, evaporation requires heat. It just so happens that the Sun often provides the heat required.
Can heat separate sunflower seeds and sand?
To separate sunflower seeds from sand you will need a fine filter, such as a screen. A screen that may work for you are the screens use in the common window.
Does a Papua New Guinea citizen need a visa to visit New Zealand?
They are separate nations, so a visa is required.
How much heat is necessary to change 220 g of ice at -5C to water at 20C?
You need to add all of the following:* The heat required to heat ice from -5 to 0 degrees. Multiply the mass times the temperature difference times the specific heat of ice. * The heat required to melt ice. Multiply the mass by the heat of fusion. * The heat required to raiste the temperature of water from 0 to 20 degrees. Multiply the mass times the temperature difference times the specific heat of water.
Why does the human body take in compounds?
We need compounds for our body to process properly. That is exactly why we need compounds. I hope this answer helps you. :)
