Answer:

D. A new substance with properties different from either of the liquids was formed.

Explanation:

This is a simple chemical reaction. When chemical reactions occur, bonds are simply broken and rearranged and new ones formed. Formation of new compounds can be seen and clearly observed. These compounds are completely different in properties from the atoms and compounds that combines to form them.

If they still share the same property in anyway, then, there was only a physical combination of the compounds and this implies the formation of a mixture

Answer:

D. A new substance with properties different from either of the liquids was formed.

The correct option that is the answer for the question is option d

Explanation:

In the given question two liquids of different colours are mixed together. One of them has yellow colour, while the other is colourless on mixing we see that the new substance that is formed is neither yellow nor colourless.

And the mixture that is formed is a substance which is not liquid and solid of red colour and we can conclude, that the mixture form does not retain any property of the elements from which it is made. Hence we can say a new substance with different properties are formed.

For the following reactions, write a balanced equation using half-reactions and calculate the voltage to be expected.

Iteru [2.4K]

a) $2Na(s) +2H_2O(I)$ → $2Na^+(aq) + OH^-(aq)+ H_2(g)$

b) $2Ag (s) +2H^(aq)$ → $2 Ag^+ (aq) +H_2(g)$

<h3>What are half-reactions?</h3>

The half-reaction method is a way to balance redox reactions. It involves breaking the overall equation down into an oxidation part and a reduction part.

$2Na(s) +2H_2O(I)$ → $2Na^+(aq) + OH^-(aq)+ H_2(g)$

$E^0 cell = E^0 (reduction) - E^0 (oxidation)$

= $E^0(\frac{H_2O}{H_2}, OH^-) -E^0(Na^+/Na)$

= -0.83 - (-2.71) =1.88V

$2Ag (s) +2H^(aq)$ → $2 Ag^+ (aq) +H_2(g)$

$E^0cell$ = $E^0(H^+/H_2) -E^0(Ag^+/Ag)$

$E^0cell$ =-0. - (0.8) =-0.8V

For ethanol, propanol, and n-butanol the boiling points, surface tensions, and viscosities all increase. what is the reason for

Contact [7]

Moving from Ethanol through Propanol to Butanol the physical properties like boiling points, surface tension and viscosity increases because of the increases in intermolecular interactions between the molecules of given compounds.

Explanation:
Ethanol, propanol and butanol all have hydroxyl groups in common, means all have hydrogen bond intractions between their molecules. So, taking the hydrogen bonding interaction constant we are left with only the difference in the number of carbon atoms.
Butanol has the greatest physical properties than other two because it has four carbon atom chain. So, as we know the London Dispersion forces or Van der Waal forces increases with increase in molecular size and chain length of hydrocarbon.
Therefore, the strength of London forces is greater in butanol than other two while ethanol has the smallest chain comparatively hence, lowest physical properties.

What are the two properties of Graphite that are different from the properties of Diamond?

Rus_ich [418]

Answer:

Graphite is insoluble in water and organic solvents - for the same reason that diamond is insoluble. Attractions between solvent molecules and carbon atoms will never be strong enough to overcome the strong covalent bonds in graphite. conducts electricity.
