Are Sharks Color Blind?
melisa1 [442]

Answer:

Sharks are color blind, which means they cannot see a lot of colors clearly, but this does not stop them from hunting their prey as they have many tricks up their sleeves. Coming up in this article, we look at what colors sharks are least attracted to, if whale sharks are blind, and if sharks are blind when they attack.

In the following chemical equation, identify the products and reactants and indicate whether or not the equation is balanced. If
aleksandr82 [10.1K]

Answer:

a). The products are C6H12O6 O2 and the reactants are CO2 + H20 + (solar (light) energy)

b). The reaction chemical reaction is balanced from the number of moles of reactants and products

Explanation:

Through photosynthesis green plants, some protistans and some bacteria in the presence of energy from sunlight, produce glucose as well as oxygen from carbon dioxide and water.

It is a chemical reaction taking place in green plant to produce food which it uses to survive.

Photosynthesis requires carbon dioxide, water and solar energy in the leaves of a plant for it to take place.

The equation for photosynthesis is as follows: 6CO2 + 6H20 + (solar (light) energy) → C6H12O6 + 6O2

The products are C6H12O6 O2

and the reactants are CO2 + H20 + (solar (light) energy)

The reaction chemical reaction is balanced from the number of moles of reactants and products

IceJOKER [234]

Answer:

The over all reaction :

2Fe^{3+}(aq)+Pb(s)\rightarrow 2Fe^{2+}(s)+Pb^{2+}(aq)  

The standard cell potential of the reaction is 0,.897 Volts.

Explanation:

Reduction at cathode :

Fe^{3+}(aq)+e^-\rightarrow Fe^{2+}(s)..[1]  

E^o_{Fe^{3+}/Fe^{2+}}=0.771 V

Reduction potential of Fe^{3+} to Fe^{2+}=0.771 V

Oxidation at anode:

Pb(s)\rightarrow Pb^{2+}(aq)+2e^-.[2]

E^o_{Pb^{2+}/Pb}=-0.126 V

Reduction potential of Pb^{3+} to Pb=-0.126 V

To calculate the E^o_{cell} of the reaction, we use the equation:

E^o_{cell}=E^o_{red,cathode}-E^o_{red,anode}

Putting values in above equation, we get:

E^o_{cell}=E^o_{Fe^{3+}/Fe^{2+}}-E^o_{Pb^{2+}/Pb}

=0.771 V-(-0.126 )=0.897 V

The over all reaction : 2 × [1] + [2]

2Fe^{3+}(aq)+Pb(s)\rightarrow 2Fe^{2+}(s)+Pb^{2+}(aq)  

The standard cell potential of the reaction is 0,.897 Volts.
