The calvin cycle and the krebs are referred to as cycles of chemical reactions because they
Schach [20]

Answer:

The options are

a. occur inside organelles. b. start over continually. c. are part of the carbon cycle. d. allow energy to flow in ecosystems.

The answer is b. Start over continually

Explanation:

The two cycles involves a continuous process as long as the reactants are present under suitable conditions. The cycle happens all the time due to it being necessary to produce important products all the time for the body system.

A good example involves the existing Carbon dioxide and water reacting together to get converted into substance that could provide energy (ATP and NADH) such as Glucose.

Write a balanced net ionic equation for the following reaction. Explain how you arrived at this answer. What did you cancel out?
yaroslaw [1]

 The net ionic equation  is


Ag⁺(aq)  +Cl⁻(aq) →  AgCl(s)


Explanation


AgNO₃ (aq)  + KCl (aq)→ AgCl(s) +KNO₃(aq)



from above  molecular equation break  all  soluble electrolyte  into ions


Ag⁺(aq) +NO₃⁻ (aq) + K⁺(aq) +Cl⁻(aq) →   AgCl (s) + K⁺(aq) + No₃⁻(aq)



cancel the spectator  ions  in both side  of  equation =K⁺  and NO₃⁻  ions



The net  ionic equation is therefore


= Ag⁺(aq)  + Cl⁻(aq) →    AgCl(s)

Should a homeowner expect more caco3 buildup in hot water pipes or cold water pipes
Arturiano [62]
Answer:
             CaCO₃ built up in hot water pipes

Explanation:

The hardness of water is classified as;

Permanent Hard Water:
                                     In this the mineral content cannot be removed by boiling. This water contains mainly following,

                                        Calcium Sulfate  CaSO₄

                                        Calcium Chloride   CaCl₂

                                        Magnesium Sulfate   MgSO₄

                                        Magnesium Chloride   MgCl₂

These salts does not precipitate out on heating water.

Temporary Hard Water:
                                     In this water the mineral content can be removed by boiling. This water contains mainly following,

                                        Calcium Bicarbonate  Ca(HCO₃)₂

                                        Calcium Carbonate  CaCO₃

                                        Magnesium Bicarbonate   Mg(HCO₃)₂

                                        Magnesium Carbonate  MgCO₃

These salts does not precipitate out on heating water. i.e.

                Ca(HCO₃)₂    -------heat------>    CaCO₃  +  CO₂  +  H₂O

The CaCO₃ are formed in the form of scales.

Result:
           Hence, we can say that that CaCO₃ built up in hot water pipes.
