Do relative proportions of elements in a given compound vary from sample to sample?
im not really sure....sorry
The chemical formula of a compound does not indicate?
The chemical formula of a compound does not indicate the way that elements are joined in the compound. Chemical formulas tell you the identity of the elements in the compound and the relative proportions of the elements.
Is a vegetable a compound or a mixture?
Potato is a mixture of several compounds mainly are Starch and water.
What is stoichiomtry?
Stoichiometry is the study of the relative proportions of elements that combine during chemical reactions.
Do the relative positions of sucrose in the periodic table agree with the theoretical prediction about the kind of compound these elements should form?
Sucrose is an ionic compound!!
What does an empirical formula show?
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
How do you find molar mass of anhydrous sodium carbonate when given the molar mass of hydrated sodium carbonate?
Add up the atomic masses of its constituent elements in their respective proportions, giving you a value of 105.988 g mol-1.
What is the principle of common proportions?
The relative proportions of ions in sea water are constant. In other words, the percentage accounted for by each ion is always the same. This implies that the oceans are chemically well-mixed and that ocean salinity varies almost entirely as a result of the addition or removal of pure water, not the addition or removal of salts. - A.J. F
How does the chemical formula of a compound relate to the relative number of atoms in the compound?
Chemical formulas consist of chemical symbols and numbers. The symbols represent the elements in the compound. The numbers indicate the quantity of atoms of each element in the compound.
What do coefficient represent?
The relative proportions of each reactant and product.
What relative proportions do the earth and moon have compare to each other?
