A100 gram block is placed on a scale that is known to have a 12% error. what will the scale read?

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change

Use the periodic table to find the molar mass of each element. molar mass h = g/mol molar mass s = g/mol molar mass o = g/mol

What sources of error may have contributed to the percent yield not being 100 percent? think about things that may have led to inaccurate measurements or where mass of the product could have been lost if this experiment was conducted in a physical laboratory.
