How do get good grades

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold

How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %
