Molar mass:
H₂O = 18.0 g/mol
O₂ = 32.0 g/mol
C₅H₁₂ + 8 O₂ -> 5 CO₂ + 6 H₂<span>O
</span>
8 x (32 g )<span> ------------ 6 x (18 g )</span>
mass O₂ ------------ 108 g H₂O
mass O₂ = 108 x 8 x 32 / 6 x 18
mass O₂ = 27648 / 108
mass O₂ =<span> 256 g</span>
<span>hope this helps!</span>
Answer:
The correct answer is m= mol solute kg soivent
Explanation:
Molality is a measure of concentration, which indicates the moles of solute (in this case sodium hydroxide) in 1kg of solvent .
In this case:
0,800 kg water-----0,400 mol NaOH
1 ,000 kg water ---x=(1 ,000 kg water x 0,400 mol NaOH)/0,800 kg water
x=0,5 mol NaOH---> <em>The solution is 0,5 molal (0,5 m)</em>
Answer:
carbon-12 is not radioactive
Explanation:
The measurement of the age of dead carbon based life forms requires the use of a radioactive isotope hence it is often referred to as radiocarbon dating.
Carbon-12 and Carbon-14 occur together in living things.The half life of Carbon-14 is about 5670 years.
Hence, since Carbon-12 is not radioactive, it can not be used to measure the age of dead carbon based materials.
Dispersion forces or London dispersion forces are collectively referred to as Van der Waals forces. These forces are temporary and arise from the relative position of electrons in one atom to another. If the electrons become distributed in an asymmetrical manner, the negative charge is concentrated at one end of the particle and a positive charge is concentrated at the other. These forces are also called induced dipole-induced dipole attraction.
