During an exothermic reaction, heat content in the surroundings increases because
ANTONII [103]

Energy is transmitted to the surrounding in an exothermic reaction and this can be understood with the energy diagram of exothermic reaction attached with the answer.

<h3>What is an Exothermic Reaction ?</h3>

When a chemical reaction happens, energy is transferred to or from the surroundings.

When energy is transferred to the surroundings, this is called an exothermic reaction, and the temperature of the surroundings increases.

ΔH value negative –> energy released –> exothermic reaction

This happens because the reactants are at the higher energy state as compared to the products and therefore heat is liberated in the atmosphere to match the difference and therefore heat content in the surroundings increases.

The energy diagram for the exothermic reaction is attached with this answer.

The fire wood sends heat out in all directions. Warmed smoke filed air goes up the chimney. The outside of the metal fireplace g
maxonik [38]

Answer:

Convection

Explanation:

Convection is a mode of heat transfer that involves the actual movement of particles. In this case the particles are air particles.

Since hot air is less dense, it is pushed up by the denser cool air. This process may continue indefinitely and a convection current is set up.

Ethylene glycol is a compound used in automotive antifreeze. It is odorless, colorless, and toxic if ingested. Adding ethylene g
const2013 [10]

Answer: Andre. If it is used as an antifreeze, one would infer that it's freezing point is less than water.

Explanation:

The freezing point of ethylene glycol alone (100%) is -12.9oC. That is somewhat less than the freezing point of water but nowhere near the freezing point of water containing 70% ethylene glycol.

What is the molarity of a solution which has a volume of 3 litres and contains 5.1 moles of Br2?
katrin [286]

Answer:

The molarity of the solution is 1.7 \frac{moles}{liter}.

Explanation:

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

Molarity=\frac{moles of solute}{volume of the solute}

Molarity is expressed in units \frac{moles}{liter}.

In this case, you know:

  • moles of solute= 5.1
  • volume= 3 L

Replacing:

Molarity=\frac{5.1 moles}{3 L}

Solving:

Molarity= 1.7 \frac{moles}{liter}

<u><em>The molarity of the solution is 1.7 </em></u>\frac{moles}{liter}<u><em>.</em></u>
