Because zinc is above lead on the activity series. This means that in a single displacement reaction such as this one, Pb will not easily displace Zn.
Answer:

<u>Answer:</u> The nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.
<u>Explanation:</u>
Nuclear reaction are defined as the reactions in which nucleus of an atom is involved.
Positron emission is defined as the emission process in which positron particle is emitted. In this process, a proton gets converted to neutron and an electron neutrino particle.

The chemical equation for the reaction of He-3 with a proton follows:

Hence, the nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.
Answer:
True
Explanation:
Water boils at 373 kelvins. ... Absolute zero is –273.15° C or –459.67° F. The "size" of a one degree change in temperature is exactly the same in the Celsius and Kelvin scales, so the freezing point of water is at a temperature of 273.15 kelvins (that is, 273.15 degrees above absolute zero
