What is crystallisation used for?
crystallisation is one of the techniques to obtain compounds (solids) in pure form.
When organisms break the bonds of organic compounds the organism can?
i did this question for biology and the answer is choice 3. i forgot what it said but its 3. YOU ARE INCORRECT MR. IT IS (D)-OBTAIN ENERGY OR REASSEMBLE THE RESLULTING MATERIALS TO FORM DIFFERENT COMPOUNDS -SOPHIE! @ Sophie: Thats what she/he said...
Which two metals explode in water?
Group 2 metals (alkaline earth metals), calcium and barium would be examples
Where in the cell do the reactions occur that require oxygen in order to obtain chemical energy from glucose?
They occur in the mitochondria, a type of organelle located in the cytoplasm.
Which term is defined as all the chemical reactions that are required to sustain?
metabolismThe reactions that build up larger molecules from smaller ones are collectively called anabolism.Breakdown reactions are collectively catabolism.
What are mixed metals?
Mixing metals we can obtain alloys or inter-metallic compounds.
Should oxidation or reduction be done to extract metals from their compounds?
A reduction reaction is frequently used to obtain pure metals.
How are transition metals compounds?
non-reactive
What Are Metals Manufactured From?
A few metals are found 'native', that is as the metal and only need separating from the surrounding materials, e.g. gold and silver. Most metals have to be chemically extracted from whatever compounds we can find. Iron is often found as its oxide and is extracted by heating with coke and limestone in a blast furnace. Sodium is found as sodium chloride and we obtain it by electrolysis of the melt. The method used depends on what will work and what it costs. Methods include displacement by carbon (coke), displacement by another metal, and electrolysis.
Which term is defined as all the chemical reactions that are requires to sustain life?
METABOLISM. Metabolism is the sum of the group of reactions to obtain energy and basic compounds from food (catabolism), and the group of reactions to form organic molecules and to use energy obtained form food (anabolism).
What must be multiplied to force to obtain work done?
Force*displacement
How are redox reactions used to obtain pure metals?
One way is electrolytic reduction of metal cations from molten salts. Another is heating with carbon, which can reduce the metal ions in many metal oxides to elemental metal atoms.
Why did Spanish move into Texas and California?
To obtain precious metals
What are two methods producers use to get energy?
Producers obtain energy through photosynthesis, where they convert sunlight into chemical energy. They can also derive energy from chemosynthesis by utilizing chemical reactions with inorganic compounds.
Which term is defined as all chemical reactions that are required to sustain life?
METABOLISM. Metabolism is the sum of the group of reactions to obtain energy
How has hydrogen gas been made through chemical reactions?
strong acids like sulphuric acid reacted with metals like zincwater reacted with alkali metalselectrolysisetc.
What does scandium obtained from?
Scandium is usually found with rare earth and uranium compounds. One by-product of these metals is scandium oxide (Sc2O3) and it usually traded in this form. To obtain metallic scandium, the oxide is first converted to a fluoride and then reduced using calcium.
