Answer:
The mass of NaOH that is required is 150 g
Explanation:
We calculate the weight of 1 mol of NaOH
Weight Na =23g/mol, Weight H= 1g/mol, Weight 0= 16g/mol
Weight NaOH =( 23+1 + 16) g/mol = 40 g/mol
1 dm3 (1000ml or 1 liter)---1 ,5 mol
2,5 dm3-------------------------x= (2,5dm3x 1,5mol)/ 1 dm3= 3, 75 mol
1mol NaOH----40 g
3, 75mol NaOH--x= (3, 75mol NaOHx40g)/1 mol NaOH= 150g
It stands to me it looks like it is a caution
Answer:
The answer to your question is: Volume = 1.074 x 10⁻⁶ m³
Explanation:
Data
Salt crystal measures 5.44 x 10⁻² m ; 2.5 x 10⁻³ m; 7.9 x 10⁻³ m
From the information I suppose it is a cube, then,
Volume of a cube = length x width x height
Volume = 5.44 x 10⁻² m x 2.5 x 10⁻³ m x 7.9 x 10⁻³ m
Volume = 0.000001074 m³
Volume = 1.074 x 10⁻⁶ m³
The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere.
I hope this helps, best of luck!
<span>Since these molecules are all non-polar, the only intermolecular force of attraction will be London dispersion forces. Since these increase by the size of the molecule, the boiling points will decrease in the same order:
Parafin > Heptadecane > hexane > 2,2-dimethylbutane > propane
For these two, hexane > 2,2-dimethylbutane, dispersion forces are greater in a molecule which is longer and unbranched compared to one which is branched and more compact.</span>
