Of course, at STP, dioxygen is a gas, but 10.0 g is still 10.0 g. We could calculate its volume at STP, which is 22.4 L × its molar quantity, approx. 8⋅L . There are 1.51×1023molecules O2 in 10.0 g O2 .
If the moon is on the other side of the earth, the water is getting pulled back because of the gravity force but if the moon is on the same side of the beach it's high tide.
Answer:
8.324 g
Explanation:
First we <u>convert 750.0 mL into L</u>:
- 750.0 mL / 1000 = 0.750 L
Then we <u>calculate the required number of moles of CaCl₂</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- Molarity * liters = moles
- 0.100 M * 0.750 L = 0.075 mol
Finally we <u>convert 0.075 moles of CaCl₂ into grams</u>, using its <em>molar mass</em>:
- 0.075 mol * 110.98 g/mol = 8.324 g
Answer:
The seafloor
Explanation:
the bottom of the ocean, aka the sea floor.
usually made from sand
<span>Well, I have personally used both A and C (provided the light frequency takes it above the work function of the condutor).
D could also work - a good conductor subject to a small voltage will carry a very large current. For instance, a flashlightg bulb filament is hot enough to emit electrons.
B is a no go.</span><span>
