Answer:


Explanation:
In this case, since neon could be considered as an ideal gas, the specific volumes at the first and second state are respectively:


Thus, the change in the specific volume turns out:

Which value has sense for the compression.
In addition, the specific enthalpy change just depend on the temperature as it is an ideal gas, therefore, since the process es isothermic:

Best regards.
Answer:
14 J of heat
Explanation:
Recall that the enthalpy of reaction is defined as the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, if all reactants and products are in their standard states. Here we have the heat of formation of six moles of the substance and we are expected to use it to obtain the the heat of formation of one mole of the compound and we can do that by simple proportion as shown below;
If 6 moles of the compound produces 84J of heat
1 mole of the substance will produce 1×84/6 = 14 J of heat
Answer:
I do not know if I am correct but I think it is the letter D I hope it helps you if it is correct pls brainliests
It would be D Because the earth orbits the sun
Answer:
D
Explanation:
To convert from celcius to kelvin add 273 to the celcius number. D has -75 celcius so if you add -75 to 273 you get 198 K
