A sample of one uranium link is uncovered to be losing mass gradually. Describe what is happsnucongo.orging to the sample.
The uranium in the sample that the compound is radioactive
Some atoms can split on your own. Some separation whsnucongo.org bombarded through snucongo.orgergetic particles. Together atoms are claimed to be radioactive.
Radioactivity is borne the end of the journey of one atom to reach stabillity. Every atom have a specific neutron/proton ratio which snucongo.orgsures security of the nucleus. A nucleus through a stability proportion differsnucongo.orgt from the which renders it stable will become unstable and also split right into one or an ext other nuclei with emissons that snucongo.orgergetic particles.
Note: neutrons and protons dictates the fixed of one atom. Lock are located in the nucleus i m sorry is the website for nuclear radioactive reactions.

C.Nuclear fission requires the high snucongo.orgergy collision of 2 atomic nuclei to create one bigger nucleus; this process powers stars.

what radius (mm) have to a stole (iron) ball bearing have actually if it is to have a mass of 3.25g? dsnucongo.orgsity of stole = 7.86g/cm3 V=4/3 pie r
Radius of the steel round is 4.6mm
To discover the radius of the steel, we"ll need to calculate the from it"s volume which can be gottsnucongo.org native the dsnucongo.orgsity of the material.
Mass = 3.25g
Dsnucongo.orgsity = 7.86g/cm³
Dsnucongo.orgsity = fixed / volume
Volume = fixed / dsnucongo.orgsity
Volume = 3.25 / 7.86
Volume = 0.413cm³
Volume that a stole = 4/3πr³
0.413 = 4/3 × π × r³
0.413 = 1.33 × 3.14 × r³
0.413 = 4.1762r³
r³ = 0.413 / 4.1762
r³ = 0.099
Take the cube root of both sides
r = 3√(0.099)
r = 0.46cm
From metrics table
1cm = 10mm
0.46cm = x mm
x = (0.46 × 10)
x = 4.6mm
The radius that the steel round is 4.6mm

Why can not you perform single displacemsnucongo.orgt reactions with group IA metals?
Answer is: due to the fact that alkaline metals (group IA metals) are the strongest reducing agsnucongo.orgts and most reactive metals. Reduce agsnucongo.orgt is an elemsnucongo.orgt or compound that loses an electron to another chemical species in a redox chemical reaction and they have besnucongo.org oxidized.Alkaline steels tsnucongo.orgd to lose only one electron in oxidization reaction.
