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.

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.

Sand:
0.0625-2mm
By another definition, in terms of particle size as used by geologists, sand particles range in diameter from 0.0625 mm (or ​1/16 mm) to 2 mm. An individual particle in this range size is termed a sand grain.

Cobble:
64-256 mm
(a) A rock fragment larger than a pebble and smaller than a boulder, having a diameter in the range of 64-256 mm (2.5-10 in., or -6 to -8 phi units) being somewhat rounded or otherwise modified by abrasion in the course of transport; in Great Britain, the range of 60-200 mm has been used.

Silt:
0.002 to 0.05mm
Silt particles are from 0.002 to 0.05 mm in diameter. Sand ranges from 0.05 to 2.0 mm. Particles larger than 2.0 mm are called gravel or stones. Most soils contain a mixture of sand, silt and clay in different proportions.

Boulders:
>256 mm
In geology, a boulder is a rock fragment with size greater than 256 millimetres (10.1 in) in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move.

How many atoms are in 4.5 x 1022 moles of CO2?

Answers

The number of atoms : N = 2.709 x 10⁴⁶

Further explanation

Given

4.5 x 10²² moles of CO₂

Required

The number of atoms

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

Input the value :

N = 4.5 x 10²² x 6.02 x 10²³

N = 2.709 x 10⁴⁶

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.

__________________________________________________________

1

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
