<span>The equation of the reaction for the production of the phosphorus trichloride is : 2P + 3CI2 = 2PCI3. Carlos added 15g of phosphorus, but there are two molecules of phosphorus in the chemical reaction, this implies that, there are 7.5g of phosphorus for each phosphorus atom, therefore, we are going to multiply both sides of the chemical reaction by 7.5. 2 * 7.5 = 15. Then 15 * 3 = 45. Thus, 45g of chlorine will be found in the product.</span>

Give an example how we use science in our every day life
leonid [27]

Answer: When you turn a light on it becomes bright :)

In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets. Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord. Manually operated on/off switches may be substituted by dimmer switches that allow controlling the brightness of lamps as well as turning them on or off, time-controlled switches, occupancy-sensing switches, and remotely controlled switches and dimmers. Light switches are also found in flashlights, vehicles, and other devices.

Which of the following statements is correct?
Vanyuwa [196]
I would say that children need adults to be responsible leaders. For example, my son has a developmental disability which means things must be done just so for him to feel comfortable. Yesterday, we wanted to meet up with my wife who was at the beach. He goes with me on the weekend to help him with his errands etc. So we went to her sports brella but she was swimming. So he wanted to go to the usual place he gets his fish and chips at another nearby place and also where he usually swims. So we left and went to that place. Then my wife called that where were we? So i said we will be back. So finally, once he got his food, I drove us back to meet my wife (instead of having him swim in his usual place). I was I believe using leadership so we could be together as a family and taking the chance that he would be okay with swimming at the other beach, and it worked out.

For which of the following reactions is S° &gt; 0.
lisabon 2012 [21]

The entropy of the given reactions increases (S° > 0):

  • 2C2H6(g) + 7O2(g) ----> 4CO2(g) + 6H2O(g) ---> S° > 0.
  • NH4Cl(s) ----> NH3(g) + HCl(g) ---> S° > 0.

<h3>What is entropy?</h3>

Entropy measure how disordered a system is. It a measure of how dispersed or random the total energy of a system is. The symbol for entropy is S.

A system in which entropy increases is one in which S° > 0.

The entropy of a system decreases when S° < 0.

Entropy of a system increases (S° > 0) if any change results in an increase in temperature, increase in number of molecules, or an increase in volume.

Considering the given systems, the entropy changes is as follows:

  • 2C2H6(g) + 7O2(g) ----> 4CO2(g) + 6H2O(g) ---> S° > 0.
  • 2CO2(g) + N2(g) ---->2CO(g) + 2NO(g) --> no change
  • 2N2(g) + O2(g) -----> 2N2O(g)  ---> decreases
  • S (s,rhombic) + 2CO(g) ----> SO2(g) + 2C (s,graphite) ---> no change
  • NH4Cl(s) ----> NH3(g) + HCl(g) ---> S° > 0.

In conclusion, an increase in volume and moles of substances results in entropy increase.
