artcher [175]3 years ago
4 0

Since Lutetium-177 is a beta and gamma emitter, the daughter nuclide produced from the decay of this radioisotope is 177Hf.

Beta emission of a radioisotope yields a  daughter nuclide whose amass number is the same as that of its parent nucleus but its atomic number is greater is greater than that of the parent nucleus by 1 unit.

Also, gamma emission does not lead to any change in the mass number of atomic number of the daughter nucleus produced.

Hence, the stable daughter nuclide, 177Hf is produced.

Using the following equation for the combustion of octane calculate the heat associated with the formation of 100.0 g of carbon
natali 33 [55]

Answer:

The right solution is "-602.69 KJ heat".

Explanation:

According to the question,

The 100.0 g of carbon dioxide:

= \frac{100.0 \ g}{114.33\  g/mole}

= 0.8747 \ moles

We know that 16 moles of CO_2 formation associates with -11018 kJ of heat, then

0.8747 moles CO_2 formation associates with,

= -\frac{0.8747}{16}\times 11018 \ KJ \ of \ heat

= -0.0547\times 11018

= -602.69 \ KJ \ heat

Why do heat (q) and work (w) have positive values when entering a system and negative values when leaving?
Papessa [141]

Energy transferred into the system is wonderful due to the fact the system ends up with greater strength while energy transferred out from the machine is negative, because the device finally ends up with much less energy.

In defining work, we awareness at the outcomes that the system (e.g. an engine) has on its surroundings. for this reason we outline work as being fine when the gadget does work at the environment (strength leaves the machine). If work is completed at the gadget (energy added to the machine), the work is bad.

The classical sign convention states that warmth switch into a device and work produced with the aid of it are tremendous, while heat transfer faraway from a device and work produced on it is negative.

Q is wonderful if warmness is added into the device from the surroundings. The take a look at tube would feel cooler if the response had been being finished in one. If the surroundings is tormented by the machine, work is poor. This indicates that energy is escaping the system.
