Answer:
Gas is made mostly of methane
I also has small amounts of other gasses such as: ethane, propane, butane, and pentane.
Explanation:
Answer: Answer:
21.03L
Explanation:
V1 = 456mL = 0.456L
T1 = 23°C = (23 + 273.15)K = 296.15K
P1 = 50atm
V2 = ?
T2 = 273.15K
P2 = 1.0atm
Note : P2 and T2 are at STP which are 1.0atm and 273.15K
To find V2, we have to use the combined gas equation,
(P1 × V1) / T1 = (P2 × V2) / T2
P1 × V1 × T2 = P2 × V2 × T1
V2 = (P1 × V1 × T2) / (P2 × T1)
V2 = (50 × 0.456 × 273.15) / (1.0 × 296.15)
V2 = 6227.82 / 296.15
V2 = 21.029L
Final volume of the gas is 21.03L
Explanation:
Answer:
41,64 liters
Explanation:
In order to change the units we need to know the equivalence of said units.
1 gal of gas equals to 3,78541 liters.
We can use cross-multiplication in order to convert it into liters:
A typical fill-up requires 41,64 liters.
An atomic number is <span>the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table or chart.</span>
A buffer is usually composed of either:
- a weak base combined with its conjugate acid, or
- a weak acid combined with its conjugate base
Now, examining each of the choices:
1- KOH and NH3: since they are both bases, thus this mixture is not a buffer
2- HBr and NaCl: since HBr is a strong acid while NaCl is the salt of another different acid, thus this mixture is not a buffer
3- HCl and HBr: these are both considered to be strong acid, thus this mixture is not a buffer
4- HCHO2 and NaCHO2: as for HCH02, it is considered a weak base while NaCHO2 is considered its conjugate base, thus this mixture is a buffer
