Thank you for your explanation, I'm however confused by the multiplication of each. For example, the first one mentions x 3 to CuBr2 and x 2 to AlBr3, this process of cancelling out to create even moles is the balancing? I also wanted to know what the proper classification was for those three you answered? I felt like I had the first two wrong, I wasn't sure if they were single or double replacement.

Suppose the temperature of a sample of ammonia gas is lowered from 19.0 °C to -25.0 °C, and at the same time the pressure is changed. If the initial pressure was 0.30 kPa and the volume decreased by 40.0%, what is the final pressure? Round your answer to 2 significant digits. Explanation Check X10 X K 0/5 © 2023 McGraw Hill LLC.
