Chemical nomenclature, I’m trying to figure out how to do this, if anyone could help I would absolutely love that! I’m trying to do the circled ones. I’d adore u if u could help me!!

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

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

Citric acid has a ph between 1 and 3.  it is considered to be aa. weak acidb. weak basec. strong based. strong acid
