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.
Answer: The destruction of crust occurs at deep-sea trenches. Oceanic rocks are pillow-shaped when formed. Rocks across the ocean floor have alternating magnetic stripes. Younger rocks are closer to mid-ocean ridges.
Answer:A and B
Explanation:
A substance is said to be polar when it is having a dipole (a delocalised positive and negative charge) or it is ionic (dissociate into ions when dissolved in water)
<span>How many atoms are present per cubic centimeter of W?
</span><span>Since it is a BCC cell, then it will have 4 atoms per unit cell.
As a solid, W adopts a body-centered cubic unit cell. How many unit cells are present per cubic centimeter of W?
</span>(19.3 g/cm^3)( 1 mol / <span>183.84 g) ( 6.022x10^23 atoms / 1 mol ) ( 1 cell / 4 atoms) = 1.58x10^22 cells / cm^3</span><span>
Hope this helps.</span>
