Answer:
The common name for 2-butanone, a readily available solvent, is B-butanone
molarity of the sodium nitrate solution = 0.496 ≈ 0.5 M
Explanation:
First we need to determine the number of moles of sodium nitrate (NaNO₃).
number of moles = mass / molecular weight
number of moles of sodium nitrate = 5.31 / 85 = 0.062 moles
Now we determine the molarity of the solution with the following formula:
molarity = number of moles / solution volume (L)
molarity of the sodium nitrate solution = 0.062 / 0.125 = 0.496 ≈ 0.5 M

Answer:
amino acids
Explanation:
Proteins are polymers made from different monomers, called amino acids.
Hope this helps.
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.
