Using the equation PV = nRT
Therefore; V = nRT / P
Need moles of glucose converted to moles of the product gas (CO2).

Molecular weight calculation:
C 6 X 12.01 = 72.06
H 12 X 1.01= 12.12
O 6 X 16.00 = 96.00
sum = 180.18
25.5 g of C6H12O6 ( 1 mol C6H12O6 / 180.18 g) ( 6 mol CO2 / 1 mol C6H12O6) = 0.84915 mol CO2 gas.
Convert temp: 37 °C + 273.15 = 310.15 K
V= ((0.84915 mol)× (0.0821 L atm / mol K) (310.15 K))/0.980 atm
V = 22.0635 L
= 22.06 L CO2

Answer from: deannajd03

The volume of dry gas is 22.11 L

calculation
by use of ideal gas equation that is Pv=nRT
where P (pressure) = 0.980 atm
V= ?
n = number of moles
R (gas constant) = 0.08205 L.atm/Mol.K
T(Temperature) = 37 +273 = 310 k

find n (number of moles)
write the equation for reaction

C6H12O6 +6O2 = 6CO2 +6H2O

find the moles of C6H12O6 = moles/molar mass = 25.5/180 = 0.142 moles

by use of mole ratio between C6H12O6 to CO2 which is 1:6 the moles of CO2 = 0.142 x6 = 0.852 moles therefore n= 0.852 moles

by making V the formula of the of the subject V= nRT/P

V =( 0.852moles x0.08205 L.atm/mol.K x310 k) / 0.980 atm = 22.11 l

Answer from: Quest

C) electrons encircling a nucleus with neutrons and protons

Answer from: Quest

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
