The mass of bismuth carbonate that decomposed is 0.445 g
calculation
write the equation for reaction
that is Bi2(CO3)3 → Bi2O3 +3 CO2
find the moles of of CO2 formed
At STP 1 mole of a gas = 22.4 L
what about 50 Ml
convert the Ml to Liters = 50/1000= 0.05 L
moles of CO2 formed is therefore= 1 mole x 0.05 L/22.4 l =2.232 x10^-3 moles
by use of reacting ratio between Bi(CO3)3 to CO2 which is 1:3 the moles of Bi(CO3)3 is = 2.232 x10^-3 x1/3= 0.744 x10^-4 moles of Bi(CO3)3
mass of Bi(CO3)3 = molar mass x number of moles
mass= 0.744 x10^-4 moles x 597.99 g/mol = 0.445 grams
Answer:
B) atmosphere cuz when water is evaporated it goes to the atmosphere
They are different and unique from the other statea of matter.
plasma is different from a gas, because it is made up of groups of positively and nagatively charged particles. In neon gas, the electrons are all bound to the nucleus
The ideal gas law may be written as
where
p = pressure
ρ =density
T = temperature
M = molar mass
R = 8.314 J/(mol-K)
For the given problem,
ρ = 0.09 g/L = 0.09 kg/m³
T = 26°C = 26+273 K = 299 K
M = 1.008 g/mol = 1.008 x 10⁻³ kg/mol
Therefore
Note that 1 atm = 101325 Pa
Therefore
p = 2.2195 x 10⁵ Pa
= 221.95 kPa
= (2.295 x 10⁵)/101325 atm
= 2.19 atm
Answer:
2.2195 x 10⁵ Pa (or 221.95 kPa or 2.19 atm)
Answer:
A
Explanation:
Osmosis is when water moves from an area of LOW solute concentration (low osmolarity) to an area of HIGH solute concentration (high osmolarity) through a semipermeable membrane
