If a compound does not dissolve in water, we can still determine if it consists of ions by conducting a conductivity test. Ions in a compound allow it to conduct electricity when dissolved in water due to the movement of charged particles. By testing the compound's conductivity in a solution that can dissociate ions, such as acetic acid, we can observe if there is an electrical current flowing, indicating the presence of ions in the compound. Additionally, we can also perform a flame test to observe the characteristic color emitted when certain ions are heated, providing further evidence of the presence of ions in the compound.
To make a 2 M solution of a compound, you would first need to determine the molar mass of the compound. Once you have the molar mass, you can calculate the amount of compound needed to make the solution by using the formula: moles = Molarity x Volume (in liters). Finally, dissolve the calculated amount of compound in the appropriate volume of solvent to make a 2 M solution.
A compound containing sand and gold could be a mixture of the two substances, where the gold particles are mixed with the sand particles. If water and iodine are added to this mixture, the water could dissolve the iodine to form a solution, leaving the sand and gold particles unchanged.
A molecule
Gold is a transition metal and sulfur is a nonmetal so the only bond here could be ionic.
Ca is the chemical symbol for calcium, an element. It is an alkali metal with atomic number 20. ------------------------------------------- The above is true, however if the element Ca is present in a solution then it will be present as part of an Ionic compound in solution, note a solution is not a mixture, element or compound, it is a SOLUTION. An insoluble compound of Ca could be present in liquid, in which case you would have a suspension. A suspension is a mixture.
Dissolve them in water. If the solution conducts electricity, then the solute is an ionic compound. If not, then it is a molecular compound.

15g of the compound will dissolve in 100g of water at 0 degrees C. If two unidentified solids of the same texture and color have different solubilities in 100 grams of water at 20 degrees C, you could conclude that they are different substances.
A compound containing sand and gold could be a mixture of the two substances, where the gold particles are mixed with the sand particles. If water and iodine are added to this mixture, the water could dissolve the iodine to form a solution, leaving the sand and gold particles unchanged.
A molecule can be either an element or a compound, depending on its composition. If a molecule consists of only one type of atom, it is an element. If a molecule is made up of two or more different types of atoms bonded together, it is a compound.
A compound document is a document that consists of other documents. It is a way of bringing a set of related documents or files together as one file. It can be a set of the same types of documents, or could consist of different kinds of files or data.
Two or more elements react now to improve the above answer when two or more elements (doesnt matter if they ere isotopes or not) come together that is when a compound is made . Compounds could be broken down but elemants can NOT,
I thought that you could test pills in vinegar to see if they dissolve. That would tell you if they dissolve in your body.
A molecule
The statement "He or she could tell you" has a compound subject - there are two nouns preceding the verb. A compound predicate would be "He could tell you about airplanes or about trains."
Glucose diffuses through dialysis tubing into the distilled water as, glucose molecules are small, it could fit through the pores of the dialysis tube. It is also because glucose is hydrophillic, (polar compound), which will dissolve in water as it is a polar compound as well.
You could stir the substance
