Answer:
Ammonium sulfate decomposes upon heating above 250 °C, first forming ammonium bisulfate. Heating at higher temperatures results in decomposition into ammonia, nitrogen, sulfur dioxide, and water. As a salt of a strong acid (H2SO4) and weak base (NH3), its solution is acidic; pH of 0.1 M solution is 5.5.
5.426 x molecules are there in a deep breath of air whose volume is 2. 35 L at body temperature 36 C and a pressure of 740 torr.
Explanation:
Data given:
volume V = 2.35 L
Temperature T = 36 Degrees or 273.15 + 36 = 309.15 K
pressure P = 740 torr OR 0.973 Atm
R = 0.08205 L atm / mole K
n (number of molecules of gas)= ?
The formula used will be
PV = nRT
Putting the value of given variables in above equation:
n =
=
= 0.0901 moles
According to Avagadro' s law that gases at equal volume, temperature and pressure contains same molecules.
number of molecules:
number of moles x avagadro number
0.0901 x 6.02 x
= 0.54 x
= 5.426 x molecules.
Answer:
c
Explanation:
C is the answer for increasing Atomic number
Answer: The new pressure is 0.509 atm
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 1.20 atm
= final pressure of gas = ?
= initial volume of gas = 580 ml
= final volume of gas = 1.45 L = 1450 ml (1L=1000ml)
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The new pressure is 0.509 atm
