Answer: A. 1,1,1
Explanation:
The coefficients that will balance the equation; NH4OH(aq) →H2O(l) + NH3(g), is 1, 1, 1, because it proves the total number of atoms of each element on the LHS and RHS of the equation are equal, hence balanced.
LHS RHS
N = 1 1
H = 5 5
O = 1 1
Answer:
1,4,2,3,8 there you go, I don't know if it is 100 percent correct
Answer:
The partial pressure of the
in the final mixture is 200 kPa.
Explanation:
Pressure of nitrogen gas when the two tanks are disconnected = 500 kPa
Pressure of the carbon-dioxide gas when the two tanks are disconnected = 200 kPa
Moles of nitrogen gas =![n_1= 2 kmol](https://tex.z-dn.net/?f=n_1%3D%202%20kmol)
Moles of carbon dioxide gas =![n_2=8 kmol](https://tex.z-dn.net/?f=n_2%3D8%20kmol)
After connecting both the tanks:
The total pressure of the both gasses in the tank = p = 250 kPa
According to Dalton' law of partial pressure:
Total pressure is equal to sum of partial pressures of all the gases
Partial pressure of nitrogen =![p_{N_2}^o](https://tex.z-dn.net/?f=p_%7BN_2%7D%5Eo)
Partial pressure of carbon dioxide=![p_{CO_2}^o](https://tex.z-dn.net/?f=p_%7BCO_2%7D%5Eo)
![p_{N_2}^o=p\times \frac{n_1}{n_1+n_2}](https://tex.z-dn.net/?f=p_%7BN_2%7D%5Eo%3Dp%5Ctimes%20%5Cfrac%7Bn_1%7D%7Bn_1%2Bn_2%7D)
![p_{N_2}^o=250 kPa\times \frac{0.2}{0.2+0.8}=50 kPa](https://tex.z-dn.net/?f=p_%7BN_2%7D%5Eo%3D250%20kPa%5Ctimes%20%5Cfrac%7B0.2%7D%7B0.2%2B0.8%7D%3D50%20kPa)
![p_{CO_2}^o=p\times \frac{n_2}{n_1+n_2}](https://tex.z-dn.net/?f=p_%7BCO_2%7D%5Eo%3Dp%5Ctimes%20%5Cfrac%7Bn_2%7D%7Bn_1%2Bn_2%7D)
![p_{CO_2}^o=250 kPa\times \frac{0.8}{0.2+0.8}=200 kPa](https://tex.z-dn.net/?f=p_%7BCO_2%7D%5Eo%3D250%20kPa%5Ctimes%20%5Cfrac%7B0.8%7D%7B0.2%2B0.8%7D%3D200%20kPa)
The partial pressure of the
in the final mixture is 200 kPa.
Answer:
True, if you slice an apple in half, you have 1/2 of an apple.
I believe since #13 (aluminum) is in the 13th row you should 13 neutrons. hope this helps :)
