Answer:
1 gram
Explanation:
1 gram= weight of 1 cubic centimeter of pure water at temperature 4°C = 1000 milligrams = 0.001 kilogram
Answer:
D. Sr < Ca < Be
Step-by-step explanation:
<em>Ionization energ</em>y decreases from top to bottom within a Group, because the valence electrons are further from the nucleus and therefore easier to remove.
Thus, <em>Sr has the lowest</em> ionization energy and <em>Be the highes</em>t.
The correct order is Sr < Ca < Be.
Lead(II) Sulfate, the second answer
Answer:
The energy of moving parts and motion
Explanation:
Mechanical energy doesn't have change in temperature or heat, so electricity and heat would be cancelled out. Mechanical energy is more about motion.
4 mol / 205g H2O = 4/.205 = 19.5 mol/kg boiling point = 100 + 19.5 • 0.51 = 109 ºC
