I can only find 2, I hope this helps
-To deliver oxygen to the cells of the body's tissues and remove carbon dioxide.
- The lungs also remove carbon dioxide from the blood. If carbon dioxide built up in a body, death would result.
Hard water contains certain minerals that can be rougher on the skin and hair.
Answer:-
0.648 M
Explanation:-
Volume of Ba(OH)2= 34.63ml/1000=0.03463 litre
Number of moles of Ba(OH)2 = 0.3275 M x 0.03463 litre
= 0.01134 moles
Since Ba(OH)2 has 2 OH in its formula,
Number of moles of OH- = 2 x 0.01134=0.02268 moles.
Volume of HCl= 35ml/1000 = 0.035 litre
At the end point number of moles of H+ = number of moles of OH-.
Number of moles of HCL= Concentration of HCl x Volume of HCl
∴ Concentration of HCl = 0.02268 moles/ 0.035 litre
= 0.648 moles/ litre
= 0.648 M
Moles of Carbon dioxide(CO2) = 2
<h3>Further explanation</h3>
Given
Reaction
2 C2H6 (g) + 7 O2 (g) —+ 4CO2 (g) + 6 H20 (g)
Required
moles of carbon dioxide
Solution
The reaction coefficient shows the mole ratio of the compounds in the reaction equation (reactants and products)
From the equation, mol ratio of C2H6 : CO2 = 2 : 4, so mol CO2 :
mol CO2 = (4/2) x mol C2H6
mol CO2 = 2 x 1
mol CO2 = 2
N = given mass/ molar mass.
n = number of moles
given mass = 2.47 g
molar mass = 197 g/mol
n = 2.47 / 197
n = 0.01253 moles.
I'm sure you wanted to ask more than this. Just put some comments in. I can do the same.
