Im not really sure but my best guess is d 52.8%
1. In this reaction, 2 moles of nitrogen gas reacts with 3 moles of oxygen gas to give 2 moles of N2O3 gas. 2 nitrogen molecules react with 3 oxygen molecules to give 2 N2O3 molecules. Under STP, one mole of an ideal gas occupies a volume of 22.4 liters. So in this reaction, 44.8 liters of nitrogen gas reacts with 67.2 liters of oxygen gas to give 44.8 liters of N2O3 gas. The total mass of the reactants (N2 and O2) is the same as the total mass of the product (N2O3). This is called mass balance of a chemical reaction.
2. According to the chemical reaction, 3 moles of chlorine gas produces 2 moles of iron(III) chloride. So, to produce 1 moles of iron(III) chloride, 3/2 (1.5) moles of chlorine gas is required. Therefore, to produce 14 moles of iron(III) chloride, 14 x 1.5 = 21 moles of chlorine is needed.
Not sure if this is correct but i would choose the steel tray.
The temperature in K is 767.4 K
<u><em> calculation</em></u>
This is calculated using the ideal gas equation
that is PV =nRT
where;
P(pressure)= 28 atm
V(volume) = 0.045 L
n(number of moles)= 0.020 moles
R( gas constant) =0.0821 L.atm/mol.K
T(temperature)= ? K\
make T the subject of the formula by diving both side of equation by nR
T =PV/nR
T ={ (28 atm x 0.045 L) /( 0.020 mol x 0.0821 L.atm/mol.K)} =767.4 K
Answer:
convection occurs in the inner core and crust
