Evaporating (Apex)
The equation h2o(s) heat -> h2o (l) describes the process of solid water (ice) melting into liquid water.
The formation of ethanol from glucose can be represented by the following chemical equation: C6H12O6 --> 2C2H5OH + 2CO2 This equation shows the conversion of one molecule of glucose into two molecules of ethanol and two molecules of carbon dioxide through a fermentation process.
When solid sodium hydroxide dissolves in water, the water heats up, demonstrating that the process of dissolving is exothermic for NaOH. (Very exothermic, in fact, releasing about 45kJ of heat per mole dissolved -- enough to heat a liter of H2O by 10C!) Since heat can be thought of as a product in an exothermic reaction, the equation is: NaOH (s) ---> Na+ (aq) + OH_ (aq) + 45kJ
KBr + H2O = Kaq+ Braq- Haq+ OHaq-
MgSO4∙7H2O(s) -heat→ MgSO4∙H2O(s) + 6H2O(g)
The equation h2o(s) heat -> h2o (l) describes the process of solid water (ice) melting into liquid water.
The equation describes the process of ice (H2O solid) absorbing heat and melting into liquid water (H2O liquid) at its melting point temperature.
This is the a change of phase from liquid to gas.
H2O(l) --> H2O(g) + heatshows the process of freezing.
The equation describes the process of water (H2O) changing from a liquid state (l) to a gaseous state (g) through the addition of heat. This is known as the phase transition of water from liquid to gas, also called vaporization or boiling.
The equation describes the process of liquid water (H2O(l)) undergoing a phase change into water vapor (H2O(g) ) when heat is added. This process is known as evaporation or boiling, depending on the temperature at which it occurs.
The equation H2O(s) plus heat → H2O(l) describes the process of melting, where solid water (ice) absorbs heat and transforms into liquid water. This phase change occurs at 0°C (32°F) under standard atmospheric pressure. The absorbed heat provides the energy needed to overcome the hydrogen bonds holding the ice structure together, allowing the molecules to move more freely in the liquid state.
Baking Soda is Sodium hydrogen carbonate(NaHCO3). When heat is given, it decomposes into Sodium carbonate(Na2CO3), Steam(H2O) and Carbon dioxide(CO2), according to the following equation:2 NaHCO3 --Δ--> Na2CO3 + H2O + CO2
The balanced equation for the decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2) when heated is: 2 H2O2 (aq) → 2 H2O (l) + O2 (g)
2H2O2------------ 2 H2O + O2 thus correct coefficient is 2
The general equation for the combustion of alkanes is: Alkane + O2 --> CO2 + H2O This equation represents the reaction of an alkane with oxygen to form carbon dioxide and water, releasing heat in the process.
The general equation for the combustion of fossil fuels is: Fossil Fuel + O2 → CO2 + H2O + heat This equation represents the process where fossil fuels react with oxygen to produce carbon dioxide, water, and heat energy.
