Please explain what does it mean by singly ionized lithium ions ? Would it be different...
a) Doubly ionized Cesium ions are accelerated to 50 km/s in an ion rocket engine. What accelerating voltage is needed assuming they start from rest? Each ionization removes one electronic charge. **(Mass is 2.225x10-25; Answer should be around 870V) b) A doubly ionized atom (charge = + 2e, where e = 1.602 X 10-19 C) falls in a field that lowers its potential energy by 2.7 X 10-16 J. Through what voltage does it fall? If the ion has mass...
A uranium and iron atom... please make steps and answer legible and explain throughout the process. Thank you A uranium and iron atom reside a distance R 26.90 nm apart. The uranium atom is singly ionized; the iron atom is doubly ionized. Calculate the distance r from the uranium atom necessary for an electron to reside in equilibrium. Ignore the insignificant gravitational attraction between the particles. Number iron ion uranium ion electron nm ? What is the magnitude of the...
What does in sub mean?? An Iron-Nickel sample from a meteorite was placed into a velocity selector and mass spectrometer. Experimenters expect 3 primary isotopes: 56Fe, 58Ni, & 60Ni. Positive ions are accelerated by an applied potential (AV) of 3300 Volts which is the same potential difference used to create the electric field in the velocity selector, where d is 1.1 cm. 1. On the figure provided, in the velocity selector region, (A) draw the direction of the electric field....
What is the formula of barium oxide? Please explain. What does the suffix -ide mean?
What could explain the simultaneous increases in the price of lithium and the production of lithium? Use supply and demand curves to explain your answer. (Hint: Price and equilibrium quantity have both increased. Would a shift in the demand curve or a shift in the supply curve lead to this result?)
what does mature economy mean? please explain in detail.
Please explain in detail What is "JAI" (Japan/ America/ India) and what impacts does it have on international business? The context is International Business. This is all I know. If I know every thing about the topic I would not have asked :) Please note that I already posted this question and it was answered. I just felt that the answer was a little bit vague. I would really appreciate if someone explains it better and in more details
please define a formula unit in your explanation. What does 3.3 *10^24 forumla units of silver phosphate mean? I know that a formula unit is the ratio of the ions in an ionic compound but how ido you apply 3.3*10^24? 2. Use the information in the answers you obtained in question number one as necessary to answer the following questions. a. Determine the number of moles in 3.3 x 10-4 formula units of silver phosphate. b. Determine the mass of...
What does “a structure S satisfies a formula ψ” mean? Explain.
