Methanol will float on glycerine.
A binary compound of oxygen with another element is called oxide. An oxide is a binary compound of oxygen and another element. Oxygen combines with metals and non-metals to form respective oxides.
Answer:
23.226 psi
Explanation:
From the source,
The mass of the carbon dioxide is:- 16.0 g
Molar mass of carbon dioxide = 44.01 g/mol
The formula for the calculation of moles is shown below:
Thus,
Moles of = 0.3636 moles
Volume = 3.79 L
n = 0.3636 mol
Temperature = 297 K
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
P × 3.79 L = 0.3636 mol × 0.0821 L.atm/K.mol × 297 K
⇒P = 2.34 atm
Also, 1 atm = 14.7 psi
So, Pressure = psi = 37.926 psi
THus, pressure by the gas is:-
P = Total pressure - Atmospheric pressure = 37.926 - 14.7 psi = 23.226 psi
<u>The carbon dioxide in the cartridge inflate a 3.79 L mountain bike tire to 23.226 psi pressure.</u>
balanced: there is one person on the bike with both feet on both pedals going at a steady pace
unbalanced: there is one person on the bike with both feet to one side of the bike swaying from side to side
balanced: there are two people on the bike with both feet on both sides and theyre both moving the same way
unbalanced: there are two people on the bike with their feet to one side and theyre not moving in the same way together
178.87 grams of sulphur dioxide is formed according to the equation given.
Explanation:
The balanced chemical reaction for the process is:
4 FeS2 + 11 O2 ⇒ 2Fe2O3(-) + 8 SO2
the reaction involving FeS and oxygen having balanced chemical equation as:
moles of oxygen given as 3.84
so when 11 moles of O2 reacts to form 8 moles SO2
3.84 moles of oxygen reacts to form x moles of SO2
=
x =
2.792 moles of sulphur dioxide will be formed
The mass can be calculated as number of moles x molar mass of 1 mole of SO2
= 2.792 x 64.066
= 178.87 grams of sulphur dioxide is formed.
