1 atm = 760 mmHg
29.8 mmHg / 760 mmHg * 1atm = 0.039 atm
11. change from gas to liquid
12. slower
13. increased
14. smaller
thenks and pls mark me brainliest :))
This is a false statement. Graduated cylinders measure volume, yes, but i'm afraid that beakers do not.
Hope this helps!
Answer: 16 neutrons
Explanation: The atomic number for any element is the number of protons in its atomic nuclei. In a neutral atom, the number of electrons are the same as the number of protons. The atomic mass (mass number) is the sum of the protons and neutrons in the nucleus. Mass number can vary due to the fact that the number of neutrons can vary. Isotopes are named for their mass numbers.
So, this element has 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number).
This isotope is phosphorus-31, which has atomic number 15.
