Which of the following laboratory procedures best illustrates the law of conservation of mass?
fomenos

The  laboratory  procedure that best  illustrate the law of conservation  is

heating 100 g of CaCo3  to produce  56 g of CaO  (answer C)

<u><em>explanation</em></u>

According to the law  of mass conservation ,  the mass of the  reactant  must   be equal  to the mass  of the product.

 According  to  option c Heating  100 g CaCO3  to produces  56 g CaO  (  40 +16=56)

The remaining mass  = 100-56  =  44  which  would the mass of CO2  [  12 + (16 x2)]= 44   since  CaCO3  decomposes to produce CaO  and  CO2


Therefore  the  mass  of reactant=   100g

                       mass  of product =  56 g +44 g =100

Therefore the laboratory    procedure for  decomposition  of CaCO<em>3</em>  illustrate the law of mass  conservation since the mass of reactant = mass of product.

13. An aerosol spray can of deodorant with a volume of 0.410 L contains 3.0 g of propane gas (CH3) as propellant. What is the pr
qaws [65]

Answer: The pressure in the can is 4.0 atm

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = ?

V = Volume of gas = 0.410 L

n = number of moles = \frac{\text {given mass}}{\text {Molar mass}}=\frac{3.0g}{44.1g/mol}=0.068mol

R = gas constant =0.0821Latm/Kmol

T =temperature =20^0C=(20+273)K=293K

P=\frac{nRT}{V}

P=\frac0.068mol\times 0.0820 L atm/K mol\times 293K}{0.410L}=4.0atm

Thus the pressure in the can is 4.0 atm
