Hey there!:
<span>Reaction stoichiometry :
</span>
Number of moles NaHCO3 :
Molar mass NaHCO3 = <span>84.007 g/mol
</span>
n = m / mm
n = 2.50 / 84.007
n = 0.0297moles of NaHCO3
2 NaHCO3 + H2SO4 = Na2SO4 + 2 CO2 + 2 H2O
2 moles NaHCO3 ----------------- 1 mole H2SO4
0.0297 moles NaHCO3 ----------- moles H2SO4
moles H2SO4 = 0.0297 * 1 / 2
moles H2SO4 = 0.0297 / 2
= 0.01485 moles of H2SO4
Therefore:
Molarity ( H2SO4 ) = moles H2SO4 / volume
0.600 M = 0.01485 / V
V = 0.01485 / 0.600
V = 0.02475 L of H2SO4
hope this helps!
Answer:
779 g of chlorine would produce 7.3 moles of AlCl₃
Explanation:
Given data:
Mass of chlorine gas = 779 g
Number of moles of Aluminium chloride formed = ?
Solution:
Chemical equation:
2AlBr₃ + 3Cl₂ → 2AlCl₃ + 3Br₂
<em>Number of moles of chlorine:</em>
Number of moles = mass/ molar mass
Number of moles = 779 g/ 71 g/mol
Number of moles = 11 mol
Now we will compare the moles of chlorine with Aluminium chloride.
Cl₂ : AlCl₃
3 : 2
11 : 2/3×11 = 7.3 mol
779 g of chlorine would produce 7.3 moles of AlCl₃.
As you travel up the air pressure decrease, so then the amount of oxygen you use to breathe also decreases
<span>A fat molecule is less soluble in water because it has three non-polar fatty acids and no polar or charged head like a phospholipid has.
Phospholipids have a polar region on one side; since water is a polar molecule, it can solubilize the phospholipids. Fats tend to be nonpolar and do not dissolve in water.</span>
