Final answer:

To calculate q, w, delta E, and delta H for the given process, we can use equations involving heat transfer, work, and change in energy. We can calculate q using the specific heat capacity, w using the ideal gas law, and delta H using the equation delta H = delta E + P(delta V).

Step-by-step explanation:

In order to calculate q, w, delta E, and delta H for the given process, we can use the equation: delta E = q + w. Let's start with calculating q, which represents the heat transferred during the process.

We can use the equation q = mc(delta T), where m is the mass of the substance, c is the specific heat capacity, and (delta T) is the change in temperature. For nitrous oxide gas, the specific heat capacity is approximately 1.04 J/(g*C).

Next, we can calculate w, which represents the work done on or by the system. Since the process is at a constant pressure, we can use the equation w = -P(delta V), where P is the pressure and (delta V) is the change in volume.

However, since the volume of a gas is directly proportional to the number of moles, we can use the ideal gas law to calculate the change in moles and then use that to calculate the change in volume.

The ideal gas law is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant (0.0821 L*atm/(mol*K)), and T is the temperature in Kelvin.

Finally, we can calculate delta H using the equation delta H = delta E + P(delta V). If the process is at constant pressure, then delta H is equal to q.
