because you need heat to combine the compounds together
How much heat is lost when 2012 grams of stream at 400 K is changed into ice at 263 K?
To determine the heat lost, we need to calculate the heat required to cool the steam from 400 K to 273 K (its condensation point), then the heat required to change it from steam to liquid water, and finally the heat required to freeze the water into ice at 273 K. These steps involve the specific heat capacities of water and steam, latent heat of vaporization, and latent heat of fusion.
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.
How many grams of ice at -12.1 can be completely converted to liquid at 14.7 if the available heat for this process is 4390?
To calculate the heat required to convert ice to liquid at a temperature of 14.7°C, we first need to heat the ice from -12.1°C to 0°C, using the specific heat capacity of ice. Then we calculate the heat required to melt the ice at 0°C to water at 0°C, using the heat of fusion of ice. Finally, we calculate the heat required to heat the water from 0°C to 14.7°C, using the specific heat capacity of water. By performing these calculations, we can determine if the available heat of 4390 J is sufficient.
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).

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.
Do you need a furnace when installing a heat pump?
Yes, a furnace is not required when installing a heat pump as the heat pump can provide both heating and cooling functions.
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.
Does a Papua New Guinea citizen need a visa to visit New Zealand?
They are separate nations, so a visa is required.
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.
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.

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. :)

How can you separate ferrous oxalate from titanium oxalate?
If you want to separate ferrous oxalate from titanium oxalate, you need to put them in an alkaline solution and introduce heat. They should break apart into their two respective oxolates.
What is the specific heat capacity of fish source?
To work out the specific heat capacity of fish source sauce you would need to first find out the amount of heat required to raise the temperature of 1g of the substance by 1oC
