Ne(neon) has the highest ionization energy among the elements above.
Answer:
See explanation below
Explanation:
You can tell that both 10.0 L and 98kPa are both initial values because they're at a "constant" temperature. You can also tell that 86kPa is the final/second value because the pressure "drops" to that value. Lastly, the "new" volume would also be the final/second value because it's "new". Hope this helps!

Answer:
Approximately 1.9 kilograms of this rock.
Explanation:
Relative atomic mass data from a modern periodic table:
To answer this question, start by finding the mass of Pb in each kilogram of this rock.
89% of the rock is
. There will be 890 grams of
in one kilogram of this rock.
Formula mass of
:
.
How many moles of
formula units in that 890 grams of
?
.
There's one mole of
in each mole of
. There are thus
of
in one kilogram of this rock.
What will be the mass of that
of
?
.
In other words, the
in 1 kilogram of this rock contains
of lead
.
How many kilograms of the rock will contain enough
to provide 1.5 kilogram of
?
.
