Answer:
<h2>1.2 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 30 g
volume= 25 mL
We have
We have the final answer as
<h3>1.2 g/mL</h3>
Hope this helps you
The third reason helped Rutherford to discover the nucleus.
Answer:
c) CH3CH2CH2CH3
Explanation:
Surface tension; The molecules inside the liquid attract the surface molecules and try to draw the them and make the liquid to assume in the shape having the least surface area. The suface tension increase with increase in intermolecular forces of surface liquid.
CH3CH2CH2CH3 is non-polar and have weak intermolecular forces such as London-dispersion forces.
(CH3)2CO, H2O and CH3OH are polar and have strong intermolecular forces such as hydrogen bonding.
C6H6 have high molecular mass, so will have stronger intermolecular forces.
The gibbs free energy of the reaction of diamond to graphite is equal to -2.90 kJ/mol. The free energy is negative which means that the reaction is spontaneous. Therefore, the forward reaction is favored. Hope this helps. Have a nice day.
