<h2>Mass preservation.</h2>
Explanation:
- Mass of the system must remain the same over time, as the system's mass cannot alter according to the law of preservation of mass for any closed system.
Landolt Experiment -
- Landolt was German chemist, He demonstrated the law of preservation of mass experimentally by utilizing H- glass tube filled with silver nitrate in appendage A and HCl corrosive in appendage B.
- The reactants were blended and a white accelerate of Silver chloride was shaped alongside nitric corrosive. The tube is weighed once more.
Hey are you from Calvert too? I got the same questions for the DBA
Answer:
About 170-180 grams of potassium nitrate are completely dissolved in 100 g.
Explanation:
Hello!
In this case, according to the reported solubility data for potassium nitrate at different temperatures on the attached picture, it is possible to bear out that about 170-180 grams of potassium nitrate are completely dissolved in 100 g; considering that the solubility is the maximum amount of a solute that can be dissolved in a solvent, in this case water.

Answer is: <span>name of the product nuclide is thorium-230.
</span>
<span>Alpha particle is
nucleus of a helium-4 atom, which is made of
two protons and two neutrons.
²³</span>⁴U → ²³⁰Th + α (alpha
particle).
Alpha
decay is radioactive decay in which an atomic
nucleus emits an alpha particle (helium nucleus) and transforms
into an atom with an atomic number that is reduced by
two and mass number that is reduced by four.
