Neither sugar (table) nor water are elements but are compounds. Mixing them produces a solution of sugar in water.
LiOH (Apex 2021)
HOH, which is water
CuSO4 + 2 KOH = Cu(OH)2(s) + K2SO4Only copper hydroxide is insoluble in water; other compounds are soluble in water.
A molecular formula shows this information. In sulfuric acid, for example, the formula is H2SO4 as you'll learn to write it. There is hydrogen (H), sulfur (S) and oxygen (O) in it, and there are specifically 2 atoms of hydrogen, one atom of sulfur, and 4 atoms of oxygen. You already guessed (and correctly!) that those numbers, the numerical subscripts, tell an investigator how many of those particular atoms are in the molecule of sulfuric acid.

Well, we can eliminate element- since both water and sugar are already compounds. And we can eliminate compound, since you can separate water and sugar (evaporate the water, sugar is left behind). So that leaves mixtures. Homogenous mean evenly mixed throughout. Heterogeneous means that it is not evenly mixed (think yogurt with all the fruit at the bottom). If all the sugar is dissolved, and not laying on the bottom in clumps, that would be a homogenous mixture. If you put in too much sugar, and you can see the extra, that could be a heterogeneous mixture. Does that make sense?
Hydrogen it depends on the other element if it is part of a compound
ZnCl2 is not a element. It is an compound. however Zn contains 30 protons.
reactants: an element and oxygen products: the oxide of the element
Carbonic acid H2CO3
It is a mixture of two chemicals: one a compound and the other an element.
Yes it is a fossil fuel.
This is a Composition Reaction (also known as Formation Reaction).... element + element ------> compound
NaCl in water is a mixture.
solution ------- Sugar dissolved in water: sugar is the solute, water is the solvent; and the solute plus the solvent - is a solution !
No because Oxygen is an element and it only contains atoms of Oxygen and nothing else, no Hydrogen at all. A compound of Hydrogen must contain Hydrogen plus something else. Water contains Hydrogen and Oxygen (H2O) so that would be a compound of Hydrogen and oxygen.
It is a mixture. It is not an element or a compound, so it has to be a mixture. Plus, almost all oils are mixtures, as in if you set them out long enough, they wil separate. This process may take a while, though.
