<u>Ans: 0.225 atm</u>
<u></u>
<u>Given:</u>
Initial volume of gas, V1 = 450 ml = 0.450 L
initial pressure, P1 = 1.00 atm
Final volume, V2 = 2.00 L
<u>To determine:</u>
Final pressure, P2
<u>Explanation:</u>
Based on ideal gas equation:
PV = nRT ----(1)
where P = pressure, V = volume, n = # moles, R = gas constant, T = temp
Under constant, T and n, eq(1) can be expressed as:
PV = constant
(or) P1V1 = P2V2
P2 = P1V1/V2 = 1.00 atm * 0.450 L/2.00 L = 0.225 atm
Silver has metallic bonding.
Silver is a very typical and main metal. The negatively charged electrons distribute themselves throughout the entire piece of metal and form non directional bonds between the positive silver ions, which is metallic bonding, and what silver contributes.
