1. SEP Construct Written Arguments Is mass conserved when wood or paper burns? Or is the mass converted to the energy that is released in the fire? Use
the Claim-Evidence-Reasoning framework to build a scientific argument to
answer this question. Your claim should include a mathematical representation of
the burning of wood, such as a balanced chemical equation. Next, support your
claim with evidence and scientific reasoning. You may conduct research to
gather the evidence you need.

(apex) when a cup of water is dropped, as the cup falls, the water in the cup falls out true or false?

Which diagram shows the correct way to represent an ionic compound of magnesium oxide?

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
