Answer:
The correct answer is - 38.15 gm of NaCl.
Explanation:
Write the balanced equation for this reaction of sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl):
2Na + Cl₂ —> 2NaCl
the mass of Na and the mass of NaCl :
Molar mass of Na = 23 g/mol
In the balanced equation = 2 × 23 = 46 g
Molar mass of NaCl = 23 + 35.5
= 58.5 g/mol
similarly in balanced equation = 2 × 58.5 = 117 g
From the balanced equation above,
46 g of Na reacted to produce 117 g of NaCl.
By converting it to 15 grams of Na.
Therefore,15 g of Na will react to produce = (15 × 117)/46 = 38.15 g of NaCl.
Thus, 38.15 g of Na
I remember this from last year haha. The dark moths populations will go down since they can’t blend in as well as the light moths.
Answer:
fungi reproduce very quickly, so there is always new growth that needs addressing.
Explanation: I hope this helps
3. It's because of the heat underneath the crust of the Earth. Because heat rises, the molten rock and such underneath the crust rises to the top and then the movement underneath causes things on top to move.
4. Plates are the different sections that the lithosphere has been cracked into. These plates once all fit together as a giant plate called Pangaea.
5. An earthquake is a sudden, sometimes violent shaking of the ground, as a result of the shifting of tectonic plates, or volcanic eruption.
6. On the magnitude scale, earthquakes range from 2.5 or less (usually never felt but strong enough to be detected by seismograph) to 8.0 or higher. Causes extreme damage; enough to destroy whole cities at once if close enough to the epicenter.
7. Depends on what kind you're looking for. I'd look it up for your specific topic.
8. To apply a forces to something, usually resulting in a stretch.
9. The action of compressing something, to flatten or squeeze by pressure
10. A strain on the layers of something because of pressure, resulting in the shifting of those layers.
11. In areas undergoing extension or stretching. It's when the crust is extended.
12. The hanging wall drops relative to the footwall.
13. This is what happens when the hanging wall <u>rises</u> relative to the footwall. (The opposite of a normal fault)
14.
