A sample of solid gallium (III) fluoride is added to pure water and allowed to come to equilibium at 25 degrees Celsius. The concentration of galium (III) is 0.049 M at equilibrium. What is the value of the solubility constant for gallium (III) flouride?

a sample of solid Cerium (III) hydroxide is added to pure water and allowed to come to equilibrium at 25 degrees Celsius. The concentration of Cerium (III) is 5.2 x 10^-6 M at equilibrium. What is the value of Ksp for cerium (III) hydroxide???

I want to order side view mirror for my car. It's a 2000 Lexus GS 300 and i called to the dealer and they ask me it's has the one with memory and the one with out memory? was does that mean? And the price for that 548 dollars ... i think the price to expensive do you know where i could order online that is cheaper?

You have a job at a meat warehouse loading inventory onto trucks for shipment to grocery stores. Each truck has a weight limit of 10,000 N of cargo. you push each crate of meat along a low-resistance roller belt to a scale and weigh it before moving it onto the truck. However, right after you weigh a 1000 N crate, the scale break. Describe a way in which you could apply Newton's laws to figure out the approximate masses of the remaining crates.

A sky diver falls at a constant speed in the spread=eagle position. After he opens his parachute, is the sky diver accelerating? If so, in which direction? Explain your answer using Newton's Laws?

Marcos is playing tug-of-war with his cat using a stuffed toy. At one instant during the game, Marcos pulls on the toy with a force of 22N, the cat pulls in the opposite direction with a force of 19.5 N, and the toy experiences an acceleration of 6.25 m/s^2. What is the mass of the toy?

You are riding in an elevator holding a spring scale with a 1-kg mass suspended from it. You look at the scale and see that it reads 9.3 N. What, if anything, can you conclude about the elevator's motion at that time?

you take a ride in fast elevator to the top of a tall buiding and ride back down while standing on a bathroom scale. During which parts of the ride will you apparent and real weight be the same? during which parts will your apparent weight be less than your real weight? More than your real weight? sketch free body diagram to support answer.

John goes for a run. From his house, he jogs north for exactly 5.0 min at an average speed of 8.0 km/h. He continues north at a speed of 12.0 km/h for the next 30.0 min. He then turns around and jogs south at a speed of 15.0 km/h for 15.0 min. Then he jogs south for another 20.0 min at 8.0 km/h. He walks the rest of the way home.

2. how far will john have to walk to get home after he finishes jogging?

you decide to flip a coin to determine whether to do your physiss or English homework first. The coin is flipped straight up

a. If the coin reaches a high point of 0.25 m above where you released it, what was its initial spped?

b. If you catch it at the same height as you released it, how much time did it spend in the air?

1. A student drops a ball from a window 3.5 m above the sidewalk. Ho fast is it moving when it hits the sidewalks?

2. A tennis ball is thrown straight up with an initial spped of 22.5 m/s. It is caught at the same distance above the ground

a. How high does the ball rise?

b. how long does the ball remain in the air?

1. A student trying out for the football team kicks the football straight up in the air. The ball hits him on the way back down. If it took 3.0 s from the time when the student punted the ball until he gets hit by the ball, what was the football's intitial velocity?

2. When the student in the previous problems kicked the football, approximately how high did the football travel?

1. Acceleration due to gravity on Mars is about one-third that on Earth. Suppose you throw a ball upward with the same velocity on Mars as on Earth.

a. How would the ball's maximum height compare to that on Earth?

b. How would its flight time compare?

2. Your sister drops your house keys dowwn to you from the second floor window. If you catch them 4.3 m from where your sister dropped them, what is the velocity of the keys when you catch them?
