Answer: option D

Explanation: In redox reaction both oxidation and reduction Occurs at a time in single reaction.

And oxidation numbers will change.

But here there was no change in oxidation no of both Cu and Na.

They are remains same before and after the reaction.

Hence it is not a redox reaction.

D - This is not a redox reaction because no electrons were transferred.

In Redox reactions, typically subscripts are replaced with a coefficient. In the equation given, each reactant and product maintains the same subscripts that they began with and did not gain a coefficient, thus, not being a redox reduction.

Hope this helps!

shtirl [24]

Answer: 0.176 atm

Explanation: Solution attached:

Use Boyle's Law to find the new pressure of the gas.

P1V1 = P2V2

Derive for P2

P2 = P1V1 / V2

= 5.5 atm ( 4.8 L ) / 150 L

= 0.176 atm

You have dissolved 10 g sodium oxide in 200 ml water.calculate concentration of the solution
e-lub [12.9K]

Answer:

0.85 Molar Na2O

Explanation:

Determine the moles of sodium oxide, Na2O, in 10 grams by dividing by the molar mass of Na2O (61.98 g/mole).

 (10 g Na2O)/(61.98 g/mole) = 0.161 moles Na2O.

Molar is a measure of concentration.  It is defined as moles/liter.  A 1 M  solution contains 1 mole of solute per liter of solvent.  [200 ml water = 0.2 Liters water.]

In this case, we have 0.161 moles Na2O in 0.200 L of solvent.

 (0.161 moles Na2O)/(0.200 L) = 0.85 Molar Na2O
