<u><em>Conduction</em></u> is your first answer. More examples are; touching a hot light bulb and walking on concrete in summer.

Your second answer is <u><em>C. Radiation</em></u>. More examples are; a sauna and a hot car motor.

Hope this helps!

-Using a skillet on the stove to cook scrambled eggs is an example of conduction. remember conduction is a substance that allows energy to flow throw easily which in this case the conductor is the skillet, once the skillet is heated the heat from the skillet goes to the eggs which is another conductor.

another example would be a chocolate bar melting in your hand. the heat that is coming from your hand is conducted into the chocolate bar.

- Using a space heater to heat up a cold room is an example of radiation. radiation is heat transfer that travels through space and through electromagnetic waves. the heat coming from the heater is high-energy molecules of gas (air).

another example would be the heat felt while sitting beside a campfire is radiant heat.


I feel like a genuis XD

Indicate whether the following balanced equations involve oxidation-reduction. Check all that apply. Check all that apply. 2H2SO
guapka [62]

Answer :  The balanced equations involve oxidation-reduction are:

(a) 2H_2SO_4(aq)+2NaBr(s)\rightarrow Br_2(l)+SO_2(g)+Na_2SO_4(aq)+2H_2O(l)

(b) 3SO_2(g)+2HNO_3(aq)+2H_2O(l)\rightarrow 3H_2SO_4(aq)+2NO(g)

(c) NaI(aq)+3HOCl(aq)\rightarrow NaIO_3(aq)+3HCl(aq)

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

(a) The given chemical reaction is:

2H_2SO_4(aq)+2NaBr(s)\rightarrow Br_2(l)+SO_2(g)+Na_2SO_4(aq)+2H_2O(l)

This reaction involve oxidation-reduction reaction because the oxidation state bromine changes from (-1) to (0) which shows oxidation and sulfur changes from (+6) to (+4) which shows reduction.

(b) The given chemical reaction is:

3SO_2(g)+2HNO_3(aq)+2H_2O(l)\rightarrow 3H_2SO_4(aq)+2NO(g)

This reaction involve oxidation-reduction reaction because the oxidation state sulfur changes from (+4) to (+6) which shows oxidation and nitrogen changes from (+5) to (+2) which shows reduction.

(c) The given chemical reaction is:

NaI(aq)+3HOCl(aq)\rightarrow NaIO_3(aq)+3HCl(aq)

This reaction involve oxidation-reduction reaction because the oxidation state iodine changes from (-1) to (+5) which shows oxidation and chlorine changes from (+5) to (-1) which shows reduction.

(d) The given chemical reaction is:

PBr_3(l)+3H_2O(l)\rightarrow H_3PO_3(aq)+3HBr(aq)

This reaction does not involve oxidation-reduction reaction because the oxidation state of element present on reactant and product side are same.
