## What is thermochemical equation chemistry?

A thermochemical equation is a chemical equation that includes the enthalpy change of the reaction. The process in the above thermochemical equation can be shown visually in the Figure below . (A) As reactants are converted to products in an exothermic reaction, enthalpy is released into the surroundings.

**What is thermochemical equation in thermodynamics?**

A thermochemical equation is a balanced chemical equation plus one or more quantities representing the accompanying changes in thermodynamic functions per mole for the reaction as written. For example H2O(s) → H2O(l) ΔH = +6.01 kJ/mol. represents the thermochemical equation for the melting of ice.

**What is thermochemical equation Ncert?**

When a balanced chemical equation not only indicates the quantities of the different reactants and products but also indicates the amount of heat evolved or absorbed, it is called thermochemical equation.

### What are the two types of thermochemical reactions?

The thermochemical reaction is of two types:

- Endothermic Reaction. Those thermochemical reactions in which heat is absorbed. Change in enthalpy for this reaction is positive.
- Exothermic Reaction. Exothermic reactions are the reaction in which the heat or the energy is evolved during the reaction.

**Is thermochemical an equation?**

A Thermochemical Equation is a balanced stoichiometric chemical equation that includes the enthalpy change, ΔH. Where {A, B, C} are the usual agents of a chemical equation with coefficients and “(±) #” is a positive or negative numerical value, usually with units of kJ.

**What is thermochemical equation example?**

Example: Reaction (1) C(graphite, s) + O2(g) → CO. This reaction comes about via two steps (a reaction sequence): (−110.5 kJ) + (−283.0 kJ) = (−393.5 kJ) = ΔH of Reaction (1) EXAMPLE OF THERMOCHEMICAL EQUATION IS When methane gas is combusted, heat is released, making the reaction exothermic. …

#### What is thermochemical equation give three examples?

Such an equation in which information about heat change is included is called a thermochemical equation. It is very important in such a case to indicate the physical state of the various species involved. Examples are: (i) C(s) + O2(g) →CO2(g) ; ΔH = -393.5 kJ.

**How to calculate final temperature?**

Final Temperature Formula. The following formula is used to calculate the final temperature when combining two substances of different heats. q1=q2. Where q1 and q2 are the heat of both objects after combination. Q = m*c*ΔT . TF= (m1*c1*t1+m2*c2*T2)/ (m1*c1+m2*c2) Where TF is the final temperature.

**How many BTU in a heater?**

Average BTU Ratings. A typical furnace is rated at 100,000 or 80,000 BTU per hour, but furnaces might be as small as 40,000 or as large as more than 200,000 BTU. A 90 percent high-efficiency rated at 60,000 BTU will deliver about 54,000 BTUs per hour of heat energy to your home.

## What is the formula for heat of reaction?

The heat change in a reaction can be calculated using the following formula: Heat change (H) = heat absorbed or given out by the aqueous solution. H = mcθ. where m = mass of the solution (in g) c = specific heat capacity of the solution (in J g -1 °C -1) θ = temperature change in the solution (in °C)

**What is the equation for final temperature?**

Calculate the final temperature of the water mixture using the equation T(final) = (m1_T1 + m2_T2) / (m1 + m2), where m1 and m2 are the weights of the water in the first and second containers, T1 is the temperature of the water in the first container and T2 is the temperature of the water in the second container.
