The Environmental Protection Agency suggests using cold tap water for cooking instead of starting with warm tap water is because our drinking water is made out lead pipes, which is a serious risk to health.

Explanation:

  • Lead is found throughout  the environment in lead found in paint, air, soil,   food and water.
  • Lead can pose  a significant risk to your health  if too much of it enters your body.  
  • Lead enters drinking water primarily  as a result of the corrosion.
  • It also contains in materials containing lead like in the water distribution system and   household plumbing.
  • Lead in drinking rarely cause of lead poisoning can significantly increase a person’s total lead exposure.
  • In particular the exposure of infants who drink baby formulas  and concentrated juices that are  mixed with water.
  • EPA estimates  that drinking water can make up  to 20% or more of a person’s  total exposure to lead which is dangerous.

hydrogen decomposes quickly when exposed to light. the reaction for decomposing hydrogen peroxide is:
Svet_ta [14]

The decomposition reaction for hydrogen peroxide is given below:

                                     2H_{2} O_{2} → 2H_{2} O + O_{2}

This is a decomposition reaction.

Reactions in which a reactant breaks into two or more products are known as Decomposition reactions.

                                          AB → A + B

here, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction

The decomposition reaction of decomposing hydrogen peroxide is exothermic. When the hydrogen peroxide undergoes a decomposition reaction, heat is also released along with water and oxygen.

Hence the  reaction for decomposing hydrogen peroxide is :

         2H_{2} O_{2} → 2H_{2} O + O_{2}

Quantum transitions that result in the characteristic sharp lines of the X-ray spectrum always involve
labwork [276]

Answer: 5

Explanation: this is because the energy level of the emitted of absorbed photon increases as the number of electron shell decreases, thereby making the inner shell have higher energy than other shells
