Every time you see molecules, atoms, & particles think of avagadros #. (6.022 x 10^23)
Answer: 13.6 grams of H2O
Solution: (4.56x10^23) x (1 mol H2O/6.022x10^23) x (18 grams H2O/1 mol H2O) = 13.6 grams of H2O
Using dimensional analysis above makes these types of problems easy.
Metals are ductile,malleable,good conductors and shiny
Answer:
The movement of substances may occur across a semi‐permeable membrane (such as the plasma membrane). A semi‐permeable membrane allows some substances to pass through, but not others.
Explanation:
<span>The answer is: C. The amount of water in the hydrosphere remains constant.
</span>The hydrosphere denotes the entire water available worldwide in lakes and streams, subsurface water, the ice of glaciers, and water vapor in the atmosphere. The water cycle is the process that converts liquid water to atmospheric water vapor (and vice versa) throughout the world.
I'm pretty sure its metals that make good conductors.
