14 as well. A neutral atom has just as many protons in its nucleus and electrons it is electronic shells.
Explanation:
The given data is as follows.
= 4.60 L, = 365 mm Hg
= 2.60 L, = ?
= (20 + 273) K = 293 K, = (36 + 273) K = 309 K
Since, number of moles of gas are equal so, according to ideal gas equation:
=
=
= 681.03 mm Hg
Thus, we can conclude that new pressure is 681.03 mm Hg.

Answer:
They are formed by windblown sand collecting around an obstruction. As organic matter is deposited by wind and waves, low herbs colonize the dune. As these plants collect more sand and organic matter, the dune increases in height becoming the fore dune.
Answer:
The half - life of U 238 is about 4.5 billion years. As time passes, the ratio of Pb 206 to U 238 will increase and it is this which enables the age of the rock to be estimated
