an airplane is flying at an altitude of 6000m over the ocean directly toward a coastline. at a certain time the angle of depression to the coastline from the airplane is 14 degrees. how much farther does the airplane have to fly before it is directly over the coastline
Mass of CuSO4● XH2O (g) = 1.6 grams BEFORE HEATING
After Heating :
Mass of H2O(g) = 1.1g
Mass of CuSO4 (g) : 0.5
QUESTION:
Use the information to calculate the number of moles of water lost and the number of moles in the anhydrous compound
The reaction 2 NO(g) ↔N2(g) + O2(g) has a Kc value of 2400 at 2000 K. If 0.850 M each of N2 and O2 are initially present in a 3.00-L vessel, calculate the equilibrium concentrations of NO, N2, and O2.
Make a c++ program that will print the average of the values of the three quizzes using function. The values of the quizzes are input values from the user.
Show two diffrent rectangles which both have a perimeter of 18cm
•5.20 (Displaying a Rectangle of Any Character)
–Modify the function created in Exercise 5.19 to form the rectangle out of whatever character is contained in character parameter fillCharacter.
–Thus if the sides are 5 and 4, and fillCharacter is "@", then the function should print the following:
Enter a character to fill the rectangle: a
Enter sides: 4 5
