Its Ksp value in pure water was experimentally determined. CuBr was found to be much less soluble in a 0.001MNaBr solution than in pure water. Which of the following correctly explains the decrease in solubility of CuBr in 0.001 M NaBr?A.)The concentration of water is much less in the NaBr solution than in pure water, reducing the rate of dissolution of the salt.B.)The presence of Na+ ions in the solution inhibits the dissolution of salts.C.)The presence of additional Br already in the solution decreases the value of the Ksp for CuBr , causing the solubility to decrease.D.)The presence of additional Br ions already in the solution means equilibrium will be reached when much less CuBr has dissolved. c, d) - Ta, b)Can it be described by a single translation rotation or reflection please help me with this for brainliest and a cookie Why was the Cleveland Massacre significant in the formation of Standard Oil?A. Standard Oil significantly improved its business practices after the Cleveland Massacre.B. Standard Oil was bought out by other Cleveland companies after the Massacre.C.

A fifteen passenger van is rented for a family vacation. The van rental is $75.00 per day, plus a $160.00 insurance fee. Which equation could be used to find x, the number of days the car be rented if they want to spend exactly $760.00 on the van rental? A. 75.00 + 160.00x = 760 00 B. 75.00x - 160.00 = 760.00 C. 75.00 - 160.00x = 760.00 D. 75.00x + 160.00 = 760.00 Eight bowls cost $160, but Adrien wants only 5 of them so how much does he have to pay?

Part AUsing opposite operations, rewrite the equation so s2 is on one side of the equation by itself.Part BWhat is the opposite operation of squaring? Using this opposite operation, rewrite the equation from question 1 so s is by itself on one side of the equation.Part CThe pyramid of Khufu, also known as the Great Pyramid of Giza, is one of the Seven Wonders of the World. Its volume is about 2,433,400 cubic meters, and its height is about 138 meters. Substitute these values into the equation from Part B, and solve the equation.Part DSearch the Internet to find the length of each side of the base of Khufus pyramid. Does this length match your calculation?Part EKhafre was a son of Khufu. He also had a pyramid built, but it was not as big as his fathers. The volume of the Pyramid of Khafre is about 2,115,072 cubic meters, and its height is about 136 meters. Approximate the length of each side of the base?Part FSearch the Internet to find the length of each side of the base of Khafres pyramid. Does this match your calculation?Part GAbout how much longer are the side lengths of the base of Khufus pyramid than Khafres?
