NaCl in water is a mixture.
Salt is a compound because Sodium is a metal with a plus 1 charge, while chloride is a nonmetal with a minus 1 charge. A mixture would be a combination of different compounds or molecules, while a solution is a suspension of ions in water or some other solvent.
air is a mixture of elements (nitrogen, oxygen, trace amounts of other elemental gases) plus compounds (water vapor, nitrogen and sulfur oxides, CO2)
Concrete is a composite construction material, composed of cement (commonly Portland cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravel or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water and chemical admixtures.
An example is water plus oil.
In the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH), the products formed are sodium chloride (NaCl) and water (H2O). This reaction is a classic example of a neutralization reaction, where an acid and a base react to form a salt and water. The balanced equation for this reaction is: HCl + NaOH → NaCl + H2O.
Sodium chloride and water form a solution, a homogeneous mixture not a compound.
Not, its a homogeneous solution (a mixture).
Yes. When NaCl is added to water, it forms a solution, which is a homogeneous mixture.
Lemon juice plus sugar plus water is a mixture, not a compound. In a mixture, the individual components retain their own properties and can be separated by physical means. In this case, the lemon juice, sugar, and water can be combined, but they do not chemically bond to form a new substance.
When NaCl (sodium chloride) and KNO3 (potassium nitrate) are mixed together, no chemical reaction occurs as each compound remains as separate ions in solution. This is known as a physical mixture or a non-reactive mixture.
Salt is a compound because Sodium is a metal with a plus 1 charge, while chloride is a nonmetal with a minus 1 charge. A mixture would be a combination of different compounds or molecules, while a solution is a suspension of ions in water or some other solvent.
You mean mixture. A mixture is a physical combination. Think salt in water. A compound is a chemical combination. Think Hydrogen plus Oxygen makes water.
air is a mixture of elements (nitrogen, oxygen, trace amounts of other elemental gases) plus compounds (water vapor, nitrogen and sulfur oxides, CO2)
Neither sugar (table) nor water are elements but are compounds. Mixing them produces a solution of sugar in water.
Sodiumchloride is dissociated in water: NaCl-------Na+ + Cl-
Sulphur plus water is a nonhomogeneous mixture.
No it does not. There is no danger with evaporating salt water.
