Explain the steps to calculate final velocity when many masses collide? 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." ...
Step 4: Use the equation to calculate the Energy released by the nuclear fusion. To calculate energy, we need to multiply the numbers as follows; {eq}E=0.3575*10^{-11} kg m^2/s^2 {/eq} Step 5: Calculate the Power produced in Nuclear Fusion using the formula: Power = Energy/...
How to calculate enthalpy change Enthalpy Change: Enthalpy change is a measure of the amount of energy released or absorbed during a chemical reaction. A negative enthalpy change indicates that heat was released (known as an exothermic reaction), while a positive enthalpy change indicates that heat...
Calculation of Enthalpy of Reaction Example 1: Calculate the temperature change that results from adding 250 J of thermal energy to 0.50 moles of mercury. Visualize the diagram of the Heat System and Surroundings with the arrow direction going into the system. Use the formula: _q = nCmΔT_ ...
In order to calculate this experimentally you have to monitor either the concentration of the reactant or product as a function of time. Once you have measurements at different times you can then plot these values and find the instantaneous rate of the reaction or the slope of the line. ...
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...
This energy is the minimum amount of energy that will be supplied to carry out the reaction. Answer and Explanation: The given energy is the energy that is released for every 2 moles of {eq}Fe_2O_3 {/eq}. As such, it is possib...
Topic: How to calculate heat of solution and enthalpy of solution (Read 6206 times) Hi, my question is in the link below: https://www.dropbox.com/s/vr99iv1u9k56q3p/dd.png?dl=0 My attempted answer is below: I'm struggling to find the mass. Is the mass 50.0mL + 25.0mL = ...
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...
