6. The fusion of 4 H-1 nuclei to produce two positrons and one other nuclei.​

Chemistry
1 answer:
KIM [24]2 years ago
3 0

Explanation:

Normally, fusion involves two heavy hydrogen nuclides but since we have 4 light hydrogen nuclides, two of which underwent positron emission, thus changing two protons into neutrons plus 2 positrons and 2 neutrinos. The resulting nucleus from this fusion reaction is an He-4 nucleus.

A substance with a density of 2.70 g/mL occupies a volume of 21.3 mL. What is the mass of the sample? Report your answer in unit
katen-ka-za [31]
We know the formula of the density:
ρ =\frac{m}{V} ;
So the mass will be equal to:
m = ρ * V = 2.70  * 21.3 = 57,51 g = 57510 mg of substance.
So the answer is 57510.

At STP, fluorine is a gas and iodine is a solid. This observation can be explained by the fact that fluorine has
motikmotik
<span>The answer is 4. The molecules of each material entice each other over dispersion (London) intermolecular forces. Whether a substance is a solid, liquid, or gas hinge on the stability between the kinetic energies of the molecules and their intermolecular magnetisms. In fluorine, the electrons are firmly apprehended to the nuclei. The electrons have slight accidental to stroll to one side of the molecule, so the London dispersion powers are comparatively weak. As we go from fluorine to iodine, the electrons are far from the nuclei so the electron exhausts can more effortlessly misrepresent. The London dispersion forces developed to be increasingly stronger.</span>
