For the balanced equation shown below, how many grams of H2O would be produced by 39.7 grams of Fe3O4? Fe3O4+4H2 → 3Fe+4H2O
For the balanced equation shown below, how many grams of CO2 will be produced, if 46.6 grams of H2O are produced? 2CH2Cl2+3O2 → 2CO2+2H2O+2Cl2
A tiny ball weighs 0.0055 kg and carries a charge of of 3.25 x10-6 C. What electric field (magnitude and direction) is needed for the ball to remain suspended in air?
Two particles A and B are released from rest, having equal charges of -5 x10-4 and initially separated from each other by 0.25m. The masses of particles A and B are 5.25x10-6 kg and 3.75x10-6 kg respectively. Find the magnitude of the initial accelerations of particles A and B.

Listed below is a combination of stresses acting at a point and referred to axes x and y in an elastic material. Using Mohr’s circle of stress determine the principal stresses at the point and their directions for each combination.
i) sigma x=-60 N/mm^2, sigma y=-36N/mm^2, shear stress (xy) =5N/mm^2
ii) sigma x=30 N/mm^2, sigma y=-50N/mm^2, shear stress (xy) =30N/mm^2
Objective:
Write a program that uses a structure named Student to store the following information about a student:
• Student ID
• Student Name
• Major
• Year Passed
The program should create two Student variables, store values in their members, and pass each one, in turn, to a function that displays the information about the student in a clearlv formatted
manner.
