The combustion of Ibuprofen C13H18O2 produces water and carbon

Chemistry
1 answer:
prohojiy [21]3 years ago
6 0

Answer:

277.7 g of CO2

Explanation:

Equation of reaction

C13H18O2 + 11O2 ---> 13CO2 + 9H2O

From the equation of reaction

1 mole of ibuprofen produces 13 moles of CO2

Molar mass of ibuprofen is 206g

Molar mass of CO2 is 44g

13 moles of CO2 weighs 572g

Therefore, 100g of ibuprofen will produce (100×572)/206 of CO2

= 277.7g

How many electrons in an atom can share the quantum numbers n = 2, l = 1?<br> 1<br> 3<br> 6<br> 10
Igoryamba
Principal quantum number is n = 2, principal quantum number gives the energy shells electrons reside in,
angular momentum quantum number , these are the number of subshells and gives how many subshells are there in energy shells, values for l range from 0 to n-1
magnetic quantum number -m- gives the specific orbital in the subshells and their orientation.
spin quantum number gives the spin of the electrons.

in this case, n = 2
the types of subshells in n=2 are 0 and 1
0 - s subshell 
1 - p subshell
the  specific number of orbitals are given by -l to +l
when l = 1
then -1, 0 and +1
therefore there are 3 orbitals in p subshell and orbitals are in 3 orientations
each orbital can hold a maximum of 2 electrons, 
since there are 3 orbitals each holding 6, there are 6 electrons to which these quantum numbers are the same
answer is 6

20 L of nitrogen gas are collected at a temperature of 50°C and 2 atm. How many grams of nitrogen gas were collected?
Andreas93 [3]

Answer:

0.1077 grams

Explanation:

First we will employ the ideal gas law to determine the number of moles of nitrogen gas.

PV=nRT

P=2 atm

V=20L

R=0.08206*L*atm*mol^-1*K^-1

T=323.15 K

Thus, 2atm*20L=n*0.08206*L*atm*mol^-1*K^-1*323.15K

K, atm, and L cancels out. Thus n=2*20mol/0.08206*323.15=1.5 moles

Lastly, we must convert the number of moles to grams. This can be done by dividing the number of moles by the molar mass of nitrogen gas, which is 14 grams.

1.5/14=0.1077 grams
