Which of the following is described by the equation h2o(s) heat -- h2o (I)?
The equation h2o(s) heat -> h2o (l) describes the process of solid water (ice) melting into liquid water.
Formation of ethanol equation?
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.
What is the balance equation for the reaction sodium hydroxide with water in an exothemic reaction?
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

Which of the following is described by the equation H2O(s) heat H2O(l)?
The equation describes the process of ice (H2O solid) absorbing heat and melting into liquid water (H2O liquid) at its melting point temperature.
Is described by the equation H2O(l) plus heat H2O(g)?
This is the a change of phase from liquid to gas.
What process is described by the equation H2O liquid gives H2O solid plus heat?
H2O(l) --> H2O(g) + heatshows the process of freezing.
Which of the following is described by the equation H2O l plus heat H2Og?
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.
What is described by the equation H2O(l) plus heat H2O(g)?
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.
What is described by the equation H2O(s) plus heat H2O(l)?
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.
What is the chemical change in baking soda?
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
What is the balanced equation for H₂O₂ plus Heat?
