. Iron is divalent to hydrogen and water.
Answer:
1. 44.11 g
2. 36.03 g
3. 8.08 g
4. 81.7%
5. 18.3%
Explanation:
1. 12.01+12.01+12.01+1.01+1.01+1.01+1.01+1.01+1.01+1.01+1.01=44.11
2. 12.01×3= 36.03
3. 1.01×8= 8.08
4.(36.03/44.11)×100= 81.7%
5. (8.08/44.11)×100= 18.3%
A meander is best described as a bend or curve in a stream channel.
The correct answer is (1) one mole of NO2.
The gram formula mass is also known as the molar mass and is defined by the mass over one mole of a substance.
Hope this helps~
Explanation:
It is known that equation for ideal gas is as follows.
PV = nRT
The given data is as follows.
Pressure, P = 1500 psia, Temperature, T =
= 104 + 460 = 564 R
Volume, V = 2.4 cubic ft, R = 10.73 
Also, we know that number of moles is equal to mass divided by molar mass of the gas.
n = 
m = 
=
= 9.54 lb
Hence, molecular weight of the gas is 9.54 lb.
- We will calculate the density as follows.
d = 
=
= 3.975 
- Now, calculate the specific gravity of the gas as follows.
Specific gravity relative to air =
= 
= 51.96
