Lithium: 0.98
beryllium: 1.57
boron:2.04
carbon:2.55
nitrogen:3.04
lithium is the answer. it means that the atoms in the left side of the periodic table have the lowest electronegativity value
and the right side atoms have the highest
hope this helps

Identify the product(s) for this reaction.
a. C7H6(NO2)3
b. H2O
c. HNO3 d. C7H9 and H2O
<u>e. C7H6(NO2)3 and H2O</u>
Answer:
A is the correct answer because the time of the day doesn't matter. it needs to be changed each time
Answer: The sodium peroxide needed per sailor in a 24 hr period is 674 grams.
Explanation:
According to ideal gas equation:
P = pressure of gas = 1.02 atm
V = Volume of gas = 150.0 ml = 0.15 L
n = number of moles of carbon dioxide = ?
R = gas constant =
T =temperature =
According to stoichiometry:
2 moles of carbon dioxide require = 2 moles of sodium peroxide
Thus 0.006 moles carbon dioxide require= moles of sodium peroxide
Mass of sodium peroxide needed for 24 hour=
Thus sodium peroxide needed per sailor in a 24 hr period is 674 grams.
