Problem: A manufacturer of refrigerators must ship at least 100 refrigerators to its two West coast warehouses. Each warehouse holds a maximum of 100 refrigerators. Warehouse A holds 25 refrigerators already, while warehouse B has 20 on hand. It costs $12 to ship a refrigerator to warehouse A and $10 to ship one to warehouse B. How many refrigerators should be shipped to each warehouse to minimize cost? What is the minimum cost?
Problem- the pKb values for bibasic base B are pKb1= 2.10 and pkB2= 7.39, calculate the pH at the flowing points in titration of 50.0mL of a .55M B with .55M HCl.
It takes 46.0 to raise the temperature of an 10.9 piece of unknown metal from 13.0 to 24.7. What is the specific heat for the metal?
How can I know the higher melting point and the higher lattice energy in this following example,
A 20.0-mL sample of 0.25 M HNO3 is titrated with 0.15 M Na OH. What is the pH of the solution after 30.0 mL of NaOH have been added to the acid
1) Describe what a buffer consists of and what purpose it serves.
Compute the mass of magnesium hydroxide produced. Silver nitrate and aluminum chloride react with each other by exchanging anion. Explain what mass in grams of AgCl is produced when 3.2g AgNO3 react with 3.0g of AlCl3
The compound para-dichlorobenzene often used in mothballs, is composed of 49.02 % carbon, 2.743 % hydrogen, and 48.24 % chlorine by weight.
After treating the water you need to decrease the pH back to 6.5. The water is held in a 200,000 gallon "pond". a. You have a 3 M HCl solution. How many mLs of this solution are required to change the pH from 9.5 to 6.5?
