Answer:
atoms of metallic element.
4. 2 miles/ hour
5. 80 hours
6. 408 miles
7. a) 0
b) 500 N [right]
c) 200 N [left]
I don’t know what it meant by resultant force, but i think it’s basically the same as net force.
Hope this helps!!
This problem is providing information about the moles of carbon dioxide, 2.76 mol, and asks for the volume this amount takes up, turning out to be 61.8 L according to the Avogadro's law:
<h3>Avogadro's law:</h3><h3 />
In chemistry, gas laws are used to relate the behavior of gases by virtue of the their pressure, volume, temperature and moles; thus several gas laws exist for us to do so, however, we here focus on the Avogadro's law which relates the volume and moles when both temperature and pressure are held constant.
In such a way, since no information on the constant variables is given, we assume the mentioned carbon dioxide is at STP, (0 °C and 1 atm), which means that we can use the following equivalence statement derived from the ideal gas law (PV=nRT):
22.4 L = 1 mol
Hence, we calculate the required volume:
