Distance= Speed x Time
1hr=60mins
60mins=3600 secs
20 x 3600=72000
72000 is your answer.
The number in isotope platinum-194 stands for the <em>total </em>amount of protons and neutrons. In other words, this is the mass. =)
fourth period
The third period is similar to the second, except the 3s and 3p sublevels are being filled. Because the 3d sublevel does not fill until after the 4s sublevel, the fourth period contains 18 elements, due to the 10 additional electrons that can be accommodated by the 3d orbitals.
Yes you can use that 1 equation.. P1V1/(n1T1) = P2V2/(n2T2) for ALL of your two state ideal gas law type problems. Use it in place of boyles, charles, avogadros, combined, etc laws...just like I showed you above
<span>(1).. write down P1V1/(n1T1) = P2V2/(n2T2) </span>
<span>(2).. rearrange for your desired unknown </span>
<span>(3).. determine what is constant and what varies.. cancel the constants </span>
<span>(4).. plug and chug.. don't forget Temperature must be on an absolute scale.. R or K.. never °F nor °C </span>
