Answer:
V = 11.2 L
Explanation:
Hello there!
In this case, according to the ideal gas equation:
It is possible to compute the volume as shown below:
Whereas the moles are computed are computed given the mass and molar mass of oxygen:
Now, since the STP stands for a temperature of 273.15 K and a pressure of 1 atm, the resulting volume is:
Best regards!
Answer:
A) 3.17 g of Zn
Explanation:
Let's consider the reduction of Zn(II) that occurs in an electrolysis bath.
Zn⁺²(aq) + 2e⁻ → Zn(s)
We can establish the following relations:
- 1 min = 60 s
- 1 A = 1 C/s
- The charge of 1 mole of electrons is 96,468 C (Faraday's constant).
- When 2 moles of electrons circulate, 1 mole of Zn is deposited.
- The molar mass of Zn is 65.38 g/mol
The mass of Zn deposited under these conditions is:
Answer:
If a chain reaction takes place, the amount of energy released would increase exponentially, so in order to control the energy release, fission must be controlled without controlling a chain reaction, so the third option is correct.
Hope this helps!
Explanation:
The products are on the right side of the equation. For this one it would be 2AlPO4 + 3CaSO4
Answer:
It is a sample of matter with both constant and definite composition
