Because in a mixture, there are no bonds formed between the elements, and therefore the proportions of each element are unknown, for the mixture as a whole.
A mixture is not a chemical change.
SFe, but the thing is that you still need to subscripts so i cant help you there
Different types of lava have different chemical compositions. Since not all rocks have the same chemical composition and lava is just liquid rock, it does not have an official formula. Most rocks (and therefore lava) are made up of a combination of the elements Oxygen, Silicon, Aluminum, Iron, Calcium, Sodium, Potassium, and Magnesium. Different types of rocks (and lava) have different amounts of these elements. Therefore, there is not a specific chemical formula for lava.
Elements cannot be separated into simpler substances or converted into another substance by chemical processes. Elements are the building blocks of matter and are represented on the periodic table by unique symbols.
in a liquid hand soap you cant see the different parts so its not a mechanical mixture
hello, It is first important to know what can be representated by a formula. It is a chemical compound in chemistry like, methane, calcium chloride CaCl2 etc. these compounds have chemical bods between the ions or radicals. But with steel it isn't like that. Steel is a mixture rather an alloy. It has no definite composition and also there are different types of steel. there isn't such for methane!! This just involves the arrangement of the atoms and no definite change in their atomic structure. Tence this proportion cant be represented by a formula. check out for the structure arrangements on the web
hydrogen is an element because it cant be broken into its atoms easily..
no because its a chemical change nd you cant get it back anyway why did i answer this
SFe, but the thing is that you still need to subscripts so i cant help you there
(NH4)3PO4 *the answer is right its just the bracket cant be brought up
no because a mixture is something you cant take apart
no because a mixture is something you cant take apart
cause chemical reactions cant be reversed
A Sias
no they cant mix
no they cant mix
An element is made up of only one type of atom and has a unique chemical symbol. Elements cannot be broken down into simpler substances by normal chemical means.
