How can one determine that a redox reaction will be nonspontaneous?
A. The oxidation potential has a negative value.
B. The reduction potential plus oxidation potential is positive.
C. The reduction potential plus oxidation potential is negative.
D. The reduction potential has a positive value.

Answers

Answer:

C: The reduction potential plus oxidation potential is negative

Explanation:

Redox reaction is a combination of reduction and oxidation reactions. A redox reaction can be nonspontaneous if the sum of reduction and oxidation potential is negative. Thus, option C is correct.

What is a redox reaction?

Redox reaction involves the transfer of the electron from an electron donor to an acceptor. This lead to the change in the oxidation number, and the charge on the atom or the molecules.

A redox reaction has been said to be nonspontaneous if the reduction and the oxidation half of the reactions add to a negative value. As there is an external voltage supplied to the reactants that have to result in a negative potential.

Therefore, option C. the redox reaction is nonspontaneous if the addition of the oxidation and reduction adds to a negative value is correct.

how to titrate cocacola because of its dark colour

Answers

Answer:

add baking soda maybe

Explanation:

Answer and Explanation

__________________________________________________________

All of the Information below is not owned by me, it is owned by CCBCMD.

__________________________________________________________

Colas are also carbonated beverages. The carbonation can produce some carbonic acid in the Cola, which would affect your results. Therefore, to ensure that you are only titrating the phosphoric acid you will use de-carbonated soda. This can easily be obtained by gently heating the soda, or as you may already know, by rapidly shaking the bottle. It is also important that we do not use diet Colas since the artificial sweeteners that they contain have acidic functional groups that will also interfere with the titration.

__________________________________________________________

Use a 25.00-mL pipet to deliver exactly 25.00 mL of room temperature, de-carbonated

Cola into a 250-mL beaker. Check out a magnetic stir bar and gently add it to the

beaker. Place the beaker on a stir plate. Set up a pH meter so that the probe is completely immersed, but in a way that the stir bar will not hit it. The tip of the probe

has a thin glass membrane. Handle it with care! Position the beaker so that the stir bar

is as close to the center of the beaker as possible for optimal stirring. It should stir

rapidly enough to ensure thorough mixing but not so rapidly as to cause splattering.

__________________________________________________________

Obtain about 75 mL of 0.0100 M NaOH in a beaker. Use this NaOH to fill a buret.

Remember that you should always rinse a buret 2-3 times with the solution that you are

about to put into it and remove air bubbles at the buret tip. If you do not remember how

The initial level of the NaOH should be at exactly

0.00 mL. Once the buret is ready, place it over the beaker containing the Cola

If a substance is a bad conductor as a solid, but a good conductor as a liquid or when dissolved into water, which type of bond is holding the compound together?

Answers

an ionic bond. covalent bonds do not conduct in a solid or a liquid state, ionic bonds conduct in a liquid state and not in a solid state.

The bond type in the substance is ionic bonding because, ionic compounds in their solid state are not conducting but the ions they furnish when dissolved in water conducts electricity.

What are ionic compounds ?

Ionic compounds are formed between metals and nonmetals. Metals are electropositive and they can easily loss electrons to from cations. Metals donate electrons to the electron deficient non metals to achieve octet.

Ionic bonding is a strong electrostatic force between opposite charged ions. Hence this bond is stronger than other types of bond. This intact bonding make them bad conductors in the solid state.

However they are electrically conducting the molten state or when dissolved in water due to the presence of free ions and electrons in the solution.

What word is the biotic factor in this sentence:
Fish breath oxygen that is dissolved in water.

Answers

Answer: Fish

Explanation:

Biotic factor is one of the component of the ecosystem. It is the living component of the ecosystem. It is affected or influenced by the non-living or abiotic components of the ecosystem like water, air, sunlight, and others. Fish is an example of biotic factor which is dependent on abiotic component that is oxygen which is the chief gas required for the breathing. The oxygen is one of the components of the water. So, the oxygen is dissolved in water and the fish acquire the oxygen through water only.

What is the genre of this story?Why is it so quiet? Why can't I move? And why is it so dark? I try to recall where I am, but I cannot remember. Blackness surrounds me.I hear a familiar voice that makes my heart flutter like a thousand butterflies. It is the voice of my friend, Maddy. She visits her grandparents here on the Gulf of Mexico every summer. She usually brings me crumbs, but today, I cannot smell anything except the sour smell of oil. Her voice sounds worried, different from the usual cheerful greeting that she calls me with every day at dusk. I try to turn towards her, but I can't move very well. My feet feel mired as if in quicksand.I hear her come closer. Her words help me understand that something has happened to my home."Oh, grandma! What is all this? They are all covered in it! It's black. Ugh! The smell is so strong I can't stand it." Maddy's tears stream down her face, mingling with mine. I hear her crying, but all is dark, like a moonless night. Where is the smiling sun? I try to stretch out to feel the warmth, but my wings do not respond. Dazed, I call out to my friends hoping they will find me in the blackness, but everything is so still. I hear nothing, except for Maddy's desperation. Her sobs, uncontrollable."Go get some towels, Maddy. Run!" Her grandma tells her, a quiet urgency in her voice. "Hey little one," grandma coos as she bends over me. I can feel her breath on my head. "We've got you and you are going to do all we can for you." All they can? I hear Maddy's hurried footsteps and feel the towel's softness enveloping me as she picks me up in her arms. She is gentle, her sobs quieting as she takes me to her home, seemingly miles and miles from my nest along the shoreline.I hear the phone ring. I hear the news on the television. "Spill...oil...negligence...BP...blame..." "What are we going to do?" I hear the door banging and neighbors' voices, shrill and urgent, coming in and out of the house. All of the sounds tell me that the emergency is intensifying.I still cannot see anything. Maybe it is good that I cannot see. If I could, I might see my home, blackened with the oil of a mishandled well deep in the ocean. I would see my friends, covered in slick crudeness. I would desperately observe the choking, billowing smoke, polluting the Gulf sky, my home. I would see my family unable to fly through the air, unable to dive into the ocean for the delicious meals we used to find there. I fear our fish are no more; they are stuck in the depths of the black, watery grave. What are we going to do? What are we going to do? I hope the humans will do something to bring light to all of the blackness.I hear Maddy, making sweet, soothing sounds as she begins to clean my feathers gently. I hear that sound often. It's the sound humans make on the beach when their babies are frightened.
