Answer:
²³⁸₉₂U → ²³⁴₉₀Th + ⁴₂He
Explanation:
Nuclei higher than Bi - 92 naturally are radioactive.
In a transmutation reaction, a new element is produced from an existing one due to radioactivity.
Nuclear fission is the radioactive process by which a heavy nucleus spontaneously decays into lighter ones with the release of a large amount of energy.
One example is the transmutation of uranium into thorium;
²³⁸₉₂U → ²³⁴₉₀Th + ⁴₂He
Answer:
a. is an excel document. i uploaded as an attachment
b. concentration = 0.327
Explanation:
in the graph i uploaded for answer a, the x variable is conductivity, while the y variable is % salinity.
the calculated regression line was calculated using excel =
y = 0.057655X - 0.00891
for answer part b,
we take x = 5.82
when we put this into the y formular
y = 0.057655(5.82) - 0.00891
y = 0.3355521 - 0.00891
y = 0.3266421
this is ≈ 0.327
in conclusion, using the standard curve, the concentration of unknown salt is 0.327. the % salinity = 0.327
An atom that gains electrons and becomes negatively charged is known as an <u>anion</u><u>.</u>

You could identify a physical property of a substance before you performed the activity because the characteristics of a material known as its physical qualities are those that may be investigated independently of the substance's chemical makeup.
This is further explained below.
<h3>What is
physical property?</h3>
Generally, Any attribute that can be measured and has a value that can be used to describe the state of a physical system is considered to be a physical property.
In conclusion, The changes that take place in a system's physical attributes may be utilized to provide a description of the transitions that take place between its momentary states.
