The pressure of the gas is 1.0 bar.
<em>pV</em> = <em>nRT</em>
<em>T</em> = (0 + 273.15) K = 273.15 K
<em>p</em> = (<em>nRT</em>)/<em>V</em> = (2.0 mol × 0.083 14 bar·L·K⁻¹mol⁻¹ × 273.15 K)/44.8 L = 1.0 bar
Tin-120 because an atom has to have a neutral charge. If an atom has 50 electrons it must have 50 protons unless it's an ion. Add 70 to the atomic mass because it has 70 neutrons on top of 50 protons. That equals to 120. Tin has an atomic number of 50 (meaning it has 50 protons) and it has roughly an atomic mass of about 118. If the given has 70 neutrons then it's a isotope of tin.
Window cleaner is ammonia dissolved in water. This is an example of a _______.
A Lithium atom that has lost ONE Electron, is called a Lithium Ion (Li+).
Trees are renewable resources because they can be replaced in a single lifetime and are replaced faster than they are harvested and used.
It can be maintained by responsible harvesting and use. One policy that many lumber companies advertise is that they plant a seed for every tree that they chop down.
Hope this helps! :)
