Answer:
the answer is D . our galaxy
Answer:
(a) 
(b) 
Explanation:
Hello,
(a) Based on the inlet conditions, we see that such carbon dioxide has an ideal behavior, so the inlet specific volume is:

Thus, the volumetric flow rate turns out:

(b) Now, by writing and energy balance we have:

Thus, since the ideal gas enthalpy does not depend on the pressure, in Cengel's A-20 table, the corresponding enthalpies at 300K and 450 K are 9431kJ/kmol and 15483kJ/kmol whose values in kJ/kg are 214.34 kJ/kg and 351.89 kJ/kg respectively, thus:

Best regards.
It would have THREE rings/energy levels. This is because of the amount of electrons each orbital can hold.

Answer:
A chemical energy is changed to a electrical energy
Answer: There are 4.375 moles in 2.5 L of 1.75 M 
Explanation:
To calculate the number of moles for given molarity, we use the equation:
Molarity of solution = 1.75 M
Volume of solution = 2.5 L
Putting values in equation , we get:
