Answer:
1g = 6.022 x 1023 AMU
Explanation:
An atomic mass unit or AMU is a physical constant which is equal to one-twelfth of the mass of an unbound carbon-12 atom.
One unified atomic mass unit is equal to 1.66 yoctograms = 1.66053904020 x 10-24 g.
1 AMU is equivalent to 1.66 x 10-24 grams and 1 gram is equivalent to 6.022 x 1023 AMU.
Thus,1g = 6.022 x 1023 AMU.
If 3 neutrons and 89 Se are produced from the nuclear fission of 235 U, the other fission product is Cesium-143.
<h3>What is nuclear fission.</h3>
Nuclear fission is a nuclear reaction in which a large nucleus splits into smaller ones with the simultaneous release of energy.
According to this question, a radioactive element called Uranium-235 undergoes nuclear fission to produce 3 neutrons and selenium-89.
Neutron has the following chemical symbol: 1/0 n, hence, three neutrons will be 3/0n.
Therefore, the mass number of the other fission product will be 235 - 89 - 3 = 143, which is a radioactive element called Cesium.
Therefore, if 3 neutrons and 89 Se are produced from the nuclear fission of 235 U, the other fission product is Cesium-143.

Answer:
5.4 tonnes.
Explanation:
The first step is to find the molar mass of Al2O3. Aluminum has a molar mass of about 27 and oxygen has a molar mass of about 16, so 2(27)+3(16)= 102g/mol=0.102kg/mol. 10200kg/0.102kg/mol=100,000 moles of Al2O3 in 10.2 tonnes. Multiplying this by the molar mass of the two aluminums, you get a total of 54*100,000=5400000g=5400kg=5.4 tonnes. Hope this helps!
Answer:
No, he is not.
Explanation:
When he let the rubber band go, the band compresses, so there's elastic potential energy in it, which will be transformed into kinetic energy when it gains velocity and flies across the room.
Then, Elias had inverted the concepts: the experiment demonstrates the transformation of elastic potential energy to kinetic energy.
