Carlos arranges his notes about radioactive decay in a graphic organizer. He wants to add the labels shown. Label 1: Photon
Label 2: Positron
Label 3: No change in mass number

A venn diagram with 2 intersecting circles with the left circle labeled gamma decay and the right labeled beta decay. There is an X in the gamma decay circle. There is a Z in the beta decay circle. There is a Y in the intersecting area.

Which is the best region for each label?

During chemistry class, carl performed several lab tests on two white solids. the results of three tests are seen in the data table. based on this data, carl has concluded that substance b must have bonds.

16. why must the number of electrons lost equal the number of electrons gained in every redox reaction? use 3 – 4 sentences in your own words to address this question. 18. what type of radiation is emitted when chromium-51 decays into manganese-51? show the nuclear equation that leads you to this answer. 19. a radioactive nucleus alpha decays to yield a sodium-24 nucleus in 14.8 hours. what was the identity of the original nucleus? show the nuclear equation that leads you to this answer.

Asample of freon gas has a volume of 2.23 liters, a pressure of 4.85 kpa, and a temperature of -1.36°c. calculate the volume at a pressure of 1.38 kpa and a temperature of 5.5°c. (show work)
