Answer:
2) total number of protons
Helium has an atomic number of one, and has only one proton in its nucleus.
Oxygen has an atomic number of 8 and an atomic mass of 16. From this we know that the atomic number measures the number of protons, and the atomic mass is the overal sum of protons and neutrons.
Many organisms need clean drinking water and we also need moisture in the air for us to stay hydrated
Answer: a prokaryotic cell lacks a nucleus and membrane, but has flagella and bound organelles
Explanation: prokaryotic cells are less complex than eukaryotic cells and are unicellular organisms
The statement of the combined gas law for a fixed amount of gas is,
PV/T = constant
Here, the units of pressure and volume must be consistent and the temperature must be the absolute temperature (Kelvin or Rankine).
0.65 atm is equivalent to 494 mmHg
Using the equation:
(755 x 500) / (27 + 273) = (494 x V) / (-33 + 273)
V = 3396 ml = 3.4 liters
