How to calculate the energy change in the reaction N_2(g) + 3H_2(g) rightarrow 2NH_3(g)? In the context of physics, explain the statement, "The moon is falling." How does a satellite function in relation to Newton's three laws?
What is stirring in reaction rate? How do you determine your expected discount rate on a stock investment? How to calculate the energy change in the reaction N_2(g) + 3H_2(g) rightarrow 2NH_3(g)? How do atoms have nuclear decay in nature? Is it due to oxygen or nitrogen?
The standard enthalpy change for the reaction is365 energy units. To calculate the change in enthalpy of a reaction using the enthalpy of the... Learn more about this topic: Standard Enthalpy of Formation | Definition, Table & Change
Is melting a chemical change? How is matter conserved in a chemical reaction? How is energy conserved in a chemical reaction? Is synthesis a chemical reaction? What is the difference between a chemical and physical reaction? How do you determine the limiting reactant in a chemical reaction?
The reaction rate, or the speed that the reaction happens at, is written as the change in concentration of a reactant or product per change in time as shown above. In order to calculate this experimentally you have to monitor either the concentration of the reactant or product as a functio...
energy states of the reactants (the inputs of a chemical reaction) or the products (the outputs). Instead, they in effect create a smoother path from reactants to products by lowering the amount of energy that needs to be "invested" in order to receive a "return" in the form of ...
To calculate the amount of heat released in a chemical reaction, use the equation **_Q = mc ΔT_**, where **_Q_** is the heat energy transferred (in joules), **_m_** is the mass of the liquid being heated (in kilograms), **_c_** is the specific heat capacity of the liqu...
Energy diagrams areused to represent the change in energy for the molecules involved in a chemical reaction. The free energy is measured along the y-axis, and the reaction coordinate is plotted on the x-axis. The reaction coordinate indicates the progress of the conversion of reactants to pro...
An easy way to visualize work as an energy transfer is to imagine pistons that move when a force is exerted on them. Hess's Law: When there are two or more balanced chemical equations to show the steps of a reaction, the change in enthalpy for the net equation is the sum of the ...
If the mass of nail used was 1.45g, calculate the number of moles of Fe2+ produced in the reaction. Quote My solution was 1.45 / 56 = 0.03 mol since 1 mol of Fe require 1 mol of H2SO4 to produce 1 mol of FeSO4. Why is this not accepted? Thanks. IMHO this is a correct approa...
