Answer:
[2 ]Na+[2 ]H2O -> [ 2] NaOH + [1]H2
The rest of the bot needs to be able to heat up to cook ur food but the handles should be cooler so u can touch them
Answer: 6:50
Explanation:
I think that is correct is use the math correctly u could get 6:50 like i got or 7:00.
Answer:
![6.022x10^{23}atoms \ Al](https://tex.z-dn.net/?f=6.022x10%5E%7B23%7Datoms%20%5C%20Al)
Explanation:
Hello,
In this case, given the described concept regarding the Avogadro's number, we can easily notice that 27.0 g of aluminium foil has 6.022x10²³ atoms as shown below based on the mass-mole-particles relationship:
![27.0gAl*\frac{1molAl}{27.0gAl} *\frac{6.022x10^{23}atoms \ Al}{1molAl} \\\\=6.022x10^{23}atoms \ Al](https://tex.z-dn.net/?f=27.0gAl%2A%5Cfrac%7B1molAl%7D%7B27.0gAl%7D%20%2A%5Cfrac%7B6.022x10%5E%7B23%7Datoms%20%5C%20Al%7D%7B1molAl%7D%20%5C%5C%5C%5C%3D6.022x10%5E%7B23%7Datoms%20%5C%20Al)
Notice this is backed up by the fact that aluminium molar mass if 27.0 g/mol.
Best regards.
