What must be done to obtain an element from its compound ore?
To obtain an element from its compound ore, the ore must undergo a process called extraction. This typically involves crushing the ore, heating it to high temperatures, and then using chemical reactions or other separation techniques to isolate the desired element in its pure form. The extracted element can then be further processed and refined as needed.
Which element must present for a compound to be classified as an organic compound?
carbon
Are crystals broken down a compound or an element?
Compound, crystal is not an element so obviously what it is made up of must be a compound <><><><> Crystals can be either an element (diamonds are carbon- and crystalline) or a compound (salt, sugar). Unsure of your meaning of "broken down".
How can one determine the empirical formula of a compound?
To determine the empirical formula of a compound, one must find the simplest whole number ratio of the elements present in the compound. This can be done by analyzing the mass percentages of each element in the compound and converting them to moles. Then, divide the moles of each element by the smallest number of moles to find the ratio of elements. This ratio represents the empirical formula of the compound.
A pure substance must be either what word or what word?
an element or a compound.
What kind of change must occur for an element to be removed from its compound?
a chemical change
What must an element be in order to replace another element in a compound?
An element must have similar chemical properties and valency as the element it is replacing in order to replace it in a compound. This ensures that the chemical reaction remains balanced and the new compound formed is stable.
Is hydrogencarbonate a compound or a element?
Niether. Hydrogencarbonate is an ion. It does not exist on its own, but must be combined with a positive ion to form a compound.
What must be multiplied to force to obtain work done?
Force*displacement
What is oxidation number of an element?
The charge an element would have if it lost or gained electrons
Is gold an organic compound?
No, gold is an element and is inorganic. In order to be organic a compound must contain carbon and hydrogen.
Is aluminum an organic compound?
No. First of all, aluminum is an element, not a compound. Second, a compound must contain carbon to be considered organic.
