When the reaction 2Li s plus 2H2O l 2LiOH aq plus H2 g what compound is in the liquid state?
LiOH (Apex 2021)
The equation AgNO3 plus Cu à CuNO3 plus Ag represents which type of reaction?
This is a displacement reaction: Copper is (barely) higher in the electromotive series than silver, so that the silver in a compound can be displaced by copper, resulting in the formation of unreacted silver.
The elements that make up a compound and the number of atoms of each element in a unit of the compound can be shown in a?
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.
If an acid donates H plus and a base produces OH- what compound is likely to be produced when acids react with bases?
When acids react with bases, they typically form water and a salt compound as products. Water is formed from the combination of the H+ ions from the acid and the OH- ions from the base, while the remaining ions combine to form a salt.

Is sugar plus pure water an element compound Homogeneous Heterogeneous?
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?
How many protons and electrons are in the element Zinc2 plus?
ZnCl2 is not a element. It is an compound. however Zn contains 30 protons.
What element or compound form if we combine C02 plus H20?
Carbonic acid H2CO3
What is reactants and products of complete combustion?
reactants: an element and oxygen products: the oxide of the element
What is magnesium oxygen plus potassium?
It is a mixture of two chemicals: one a compound and the other an element.
Is NaCl plus water a compound or mixture?
NaCl in water is a mixture.
Is a sugar cube a solute solvent or solution?
solution ------- Sugar dissolved in water: sugar is the solute, water is the solvent; and the solute plus the solvent - is a solution !
Is concrete a element or compound?
Concrete is a mixture.Concrete is composed of cement and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravels or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures
Is olive oil a element or compound or mixture?
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.
What element has an Oxidation number of plus 1 and - 1?
Hydrogen it depends on the other element if it is part of a compound
Is NaCl plus H2O a compound or mixture?
Sodium chloride and water form a solution, a homogeneous mixture not a compound.
Which is usually the larger number the mass number of an element or the formula mass of a compound that contains the element?
The formula mass of a compound that contains the element would be a larger number than the mass number of the individual element. The individual element would simply be the mass of just that one atom, where as the compound would be the mass of that atom plus the other masses of the other atoms that make up the compound. ex. Oxygen-O has a mass number of about 16 grams. Water-H2O has a formula mass of 2 x mass of Hydrogen-H (about 1) + the mass of Oxygen-O 16 = 18 grams. A formula mass of 18 g is more than a mass number of 16 g.
