3 P4 + 5O2 W P4O10 K= [P4O10]/ [P4] [O2]5 Calculating equilibrium Constants Lets look at the equilibrium that describes waht happens when acetic acid dissociates in water. What do you think the expression for the reverse reaction lC + mDW jA + kB is? 4 Along the same lines, what is we have a […]
The pressure of 2.4 L of nitrogen gas in a flexible container is decreased to one-half its original pressure, and its absolute temperature is increased to double the original temperature. The volume is now Select one: a. 2.1 L. b. 4.2 L. c. 8 L. d. 17 L. e. 9.6 L. Previous page
Given the reaction: CuSO4(s)<->Cu2(aq)+SO4(aq)The CuSO4 dissolves more rapidly when it is powdered because the increased surface area due to powdering permits..
an observe A, see another observer,B,as moving with velocity (u,v,0)and B sees C moving with a velocity of (u,0,v).what is the speed of C relative to A?
Two small insulating spheres with radius 4.00×10−2 are separated by a large center-to-center distance of 0.595 . One sphere is negatively charged, with net charge -2.40 , and the other sphere is positively charged, with net charge 3.70 . The charge is uniformly distributed within the volume of each sphere.
A multiple choice problem presents radio buttons for student input. Students can only select a single option presented. Multiple Choice questions have been the subject of many areas of research due to the early invention and adoption of bubble sheets. One of the main elements that goes into a good multiple choice question is the […]
What would you weigh if the Earth weretwo times as massive as it is and its radiuswere six times its present value?
Ozone gas is a form of elemental oxygen containing molecules with three oxygen atoms, O3. Ozone is produced from atmospheric oxygen gas O2, by the high energy outbursts found in lightening storms. Write the unbalanced equation for the formation of ozone gas from oxygen gas. (Include states-of-matter under SATP conditions in your answer.)
Which of the following correctly rationalizesthe increase in atomic radii down and to theleft on the periodic table, based on what wediscussed in class?1. Because the elements are easier to ionize, they have a larger electronegativity, andtherefore their electron affinity is not suffi-cient to reduce atomic radii.2. As you move to the left across a […]
