Answer:
The reaction type is double displacement
Answer:
There was an improvement in accuracy. There was no change in precision.
Explanation:
<em>The average mass after recalibration is closer to the mass of the standard, </em>so the recalibration improved the accuracy<em> </em>(the measurement is closer to an accepted 'true' value).
The standard deviation did not change, so the precision (or how disperse the measurements are) was not affected.
Answer: The answer to this question is transpiration.
Explanation: I know this answer because i looked it up in a book. The other explanation is I study about this a lot.
Decay constant, proportionality between the size of a population of radioactive atoms and the rate at which the population decreases because of radioactive decay.
<h3>What is decay constant value?</h3>
The rate of disintegration is proportional to the number of atoms at any point in time and the constant of proportionality is called the radioactivity decay constant. The radioactive decay constant for Radium B is approximately 4.3 × 10−4 s−1.
<h3>What is decay constant unit?</h3>
Definition. The decay constant (symbol: λ and units: s−1 or a−1) of a radioactive nuclide is its probability of decay per unit time. The number of parent nuclides P therefore decreases with time t as dP/P dt = −λ. The energies involved in the binding of protons and neutrons by the nuclear forces are ca.
