The equation ( \text{H}_2\text{O}(l) \rightarrow \text{H}_2\text{O}(s) + \text{heat} ) represents the process of freezing, where liquid water (H2O in its liquid state) transitions to solid ice (H2O in its solid state) by releasing heat. This occurs when the temperature drops below the freezing point of water (0°C or 32°F), causing the water molecules to lose energy and form a crystalline structure. The release of heat during this phase change is an exothermic process.

How do you valance s plus hno3 equals so2 plus no2 plus h2o?

10S + 40 HNO3 → 10 H2SO4 + 40 NO2 + H2OS + 6HNO3 → H2SO4 + 6NO2 + 2H2OS + 4HNO3 -→ SO2 + 4NO2 + 2H2O


Energetically what must be done or what must happen before water can boil?

Before water can boil, energy in the form of heat must be applied to the water to raise its temperature to the boiling point, which is 100°C (212°F) at sea level. As heat is applied, the water molecules absorb the energy and become more energetic, eventually reaching a point where the hydrogen bonds holding the water molecules together break, resulting in the water transitioning from a liquid to a gas state known as steam.

This is not a chemical formula or equation.


For the reaction 2 hclaq plus k2so3s h2ol plus so2g plus 2 kclaq answer the following questions how many grams of k2so3s would be required to react completely with 150.0 ml of 0.353 m hcl?

If you added less than the amount needed in part (b) of K2SO3, what would be the limiting reactant? If you added more than the amount needed in part (b) of K2SO3, what would be the limiting reactant? Which situation would create the most SO2 gas?excess HClexcess K2SO3 excess H2Oexcess KClperfectly matched amounts of HCl and K2SO3


What is the excess heat removed by condenser?

The excess heat removed by a condenser is the heat absorbed by the refrigerant in the evaporator plus the heat of compression in the compressor. The condenser releases this heat to the outside environment, allowing the refrigerant to return to its liquid state.
