that would be waste exchange
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:
the volume must be higher
Answer:
The temperature is "298.51 K".
Explanation:
The given values are:
Density of ammonia,
d = 0.812 g/L
Pressure,
P = 1.17 atm
Mass:
M = ![NH_3](https://tex.z-dn.net/?f=NH_3)
= ![14+ 1\times 3](https://tex.z-dn.net/?f=14%2B%201%5Ctimes%203)
= ![17](https://tex.z-dn.net/?f=17)
As we know,
⇒ ![PV=nRT](https://tex.z-dn.net/?f=PV%3DnRT)
∴ ![T=\frac{PV}{nR}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7BPV%7D%7BnR%7D)
![=\frac{PV}{\frac{W}{M}\times R }](https://tex.z-dn.net/?f=%3D%5Cfrac%7BPV%7D%7B%5Cfrac%7BW%7D%7BM%7D%5Ctimes%20R%20%7D)
![=\frac{PVM}{W\times R}](https://tex.z-dn.net/?f=%3D%5Cfrac%7BPVM%7D%7BW%5Ctimes%20R%7D)
By putting the value of "W", get
![=\frac{PVM}{V\times d\times R}](https://tex.z-dn.net/?f=%3D%5Cfrac%7BPVM%7D%7BV%5Ctimes%20d%5Ctimes%20R%7D)
![=\frac{P\times M}{d\times R}](https://tex.z-dn.net/?f=%3D%5Cfrac%7BP%5Ctimes%20M%7D%7Bd%5Ctimes%20R%7D)
On substituting the values in the above equation, we get
![=\frac{1.17\times 17}{0.812\times 0.08205}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1.17%5Ctimes%2017%7D%7B0.812%5Ctimes%200.08205%7D)
![=\frac{19.89}{0.06699}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B19.89%7D%7B0.06699%7D)
![=298.51 \ K](https://tex.z-dn.net/?f=%3D298.51%20%5C%20K)
