CaO(aq) + 2HCl(aq) -> CaCl2(aq) + H2O(l)
An ionic bonded and dissociated compound, calcium oxide, reaction with a fully dissociated strong acid, hydrochloric acid that produces a dissociated salt, calcium chloride and water.
When copper chloride reacts with aluminum foil, a chemical change occurs. This reaction results in the formation of copper metal and aluminum chloride. The color change (from blue to brown/red) and the formation of a solid precipitate are indicators of a chemical reaction taking place.
A chemical reaction can be symbolically represented using a chemical equation, where reactants are shown on the left side and products are shown on the right side. The equation includes chemical formulas of the substances involved and indicates the balance of atoms before and after the reaction.
Heating potassium chloride crystals is a physical change because it only affects the physical state of the substance (solid to liquid) without changing its chemical composition.
No, heating sodium chloride is a physical change rather than a chemical change. When heated, sodium chloride simply changes physical state from a solid to a liquid (molten form) without any change in its chemical composition.
Yes, melting sodium chloride is a physical change because it involves a change in state from a solid to a liquid without altering the chemical composition of the substance.
When copper chloride reacts with aluminum foil, a chemical change occurs. This reaction results in the formation of copper metal and aluminum chloride. The color change (from blue to brown/red) and the formation of a solid precipitate are indicators of a chemical reaction taking place.
A balanced chemical equation does not provide information on the physical amount or quantity of reactants involved in a reaction, such as miles. The coefficients in a balanced chemical equation represent the mole ratio of reactants and products, not physical quantities like miles. To determine how many moles or amount of reactant is involved in a reaction, one would need to use stoichiometry calculations based on the coefficients in the balanced equation and known quantities.
C6H12O6 + 6 O2 = 6 CO2 + 6 H2OThis is the correctly balanced equation for the combustion of Fructose. Physical states depend on how its being combusted so I left them off.
The reaction between Mentos (containing nucleation sites) and soda (containing carbon dioxide) is a physical reaction that causes the rapid release of carbon dioxide gas. This reaction is not a chemical reaction, so there is no balanced chemical equation for it.
Sodium chloride is a chemical compound (NaCl), not a property.
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
The balanced equation for nitric acid and calcium hydroxide is 2HNO3(aq) + Ca(OH)2(aq) → Ca(NO3)2(aq) + 2H2O(l). The physical state of the reactants and products are shown in parentheses: (aq) signifies aqueous solution, and (l) denotes liquid.
In a balanced chemical equation, the coefficients represent the relative ratio of moles of reactants and products, not the actual number of molecules. Changing the coefficients would alter the stoichiometry of the reaction, affecting the amounts of substances consumed and produced. Thus, individual coefficients by themselves do not hold specific physical significance.
The dissolution of sodium chloride in water is considered a physical change because no new substances are formed - the sodium chloride remains as sodium and chloride ions in the water solution.
That would probably be something like a "physical equation".That would probably be something like a "physical equation".That would probably be something like a "physical equation".That would probably be something like a "physical equation".
Sodium chloride is NaCl, calcium chloride is CaCl2. Consequently all the physical and chemical properties are different.
The physical appearance of Sodium chloride is a white crystalline solid.
