Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock. It's often much easier to date volcanic rocks than the fossils themselves or the sedimentary rocks they are found in.

for making a scatter plot of the data set, which would be the best scale and interval for the axis that represents the amount of
Sphinxa [80]

The best scale and interval to adopt for the amount of Fluoride axis would be 0 to 8 with intervals of 0.2

To make a decision on the scale and interval to adopt when making a graph ;

  • We need to examine the the range of the values in the distribution.

  • Data for the amount of Fluoride ranges from 0.4 to 7.1

  • The number of values in the distribution is 7.

  • Lower scale value must be below the minimum Fluoride value preferably 0

  • Maximum scale value must be above the maximum Fluoride value.

  • Hence an interval of 0 to 8 would suit the axis.

  • The interval is the value of each unit represented on the graph.

  • A scale of 4 would be too large to depict all the 7 values with an interval of 8 units

  • Hence, the most reasonable scale from the option would be 0.2 as it would allow the points to be properly spaced on the graph.

Why do we want to know how much and type of precipitation?
kicyunya [14]

Answer:

How many moles of neon would be contained in 4.0 l of neon gas at 2 atm and 127oc?
Sergeeva-Olga [200]

If the pressure, volume, and temperature are 202650 Pa, 0.004 cubic meters, and 400.15 K. Then the number of the mole is 0.24 mol.

<h3>What is thermodynamics?</h3>

It is a branch of science that deals with heat and work transfer.

We know that the Ideal gas equation is given as

PV = nRT

Where

P = Pressure (Pa)

V = Volume (in m³)

n = Number of moles (mol)

R = universal gas constant (8.314 J⋅K⁻¹⋅mol⁻¹)

T = temperature (in K)

We have

P = 2 atm = 202.65 × 10³ Pa

V = 4 liters = 0.004 m³

T = 127 °C = 400.15 K

Then we have

Then the number of the mole will be

\rm n = \dfrac{PV}{RT}\\\\\\n = \dfrac{202.65 \times 10^3 \times 0.004}{8.314 \times 400.15}\\\\\\n = \dfrac{810.6}{3326.85}\\\\\\n = 0.24365 \approx 0.24
