This is thermodynamics. When you increase the temperature of an object, the particles gain on kinethic energy ergo the move faster. When you decrease it, they slow down.

Explanation:

When there is increase in temperature then vibration between the atoms or molecules increases.  

This leads to decrease in force of attraction between the molecules. As a result, there will be increase in motion of molecules.

Thus, we can conclude that as temperature increases kinetic energy of molecules increases which leads to greater movement of particles.

Use the half-reaction method to balance the following equation in acidic solution. It is not necessary to include any phases of
yawa3891 [41]

Answer:

2H⁺ + 2MnO4⁻ + 3CN⁻ → 2MnO₂  + H₂O + 3CNO⁻

Explanation:

CN⁻   +   MnO4⁻  →  CNO⁻   +   MnO₂

In right side permangante, with Mn element has +7 as oxidation number.

In the MnO₂, Mn acts with +4.

This is the half reaction of reduction, where the Mn has gained 3 electrons.

in right side, cianide with C element has +2 as oxidation number. In the anion cianate, C acts with +4.

The oxidation number has increased in this half reaction. It's oxidation where the C, has lost 2 elecontrons

( 4H⁺ + MnO4⁻ + 3e⁻  → MnO₂  + 2H₂O ) .2

(H₂O  +  CN⁻  →  CNO⁻  + 2e⁻  + 2H⁺) .3

I have to add water, to ballance the amount of oxygens and protons to ballance H, in the opposite side

To ballance the half reactions, I have to multiply x2 (reduction) and x3 (oxidation)  so I can cancel, the electrons.

2H⁺  +  2MnO4⁻ + 3CN⁻ → 2MnO₂  + H₂O + 3CNO⁻

The electrons are now cancelled, and I can also modify water. In reactant side I have 3H₂O and in product side, I have 4H₂O so, H₂O in right side is gone so I finally obtained 1 H₂O on left. I had 8H⁺ on right, and 6H⁺ on left, so finally I obtained 2H⁺ on right, and the protons of product side are gone.

What type of consumer are bears?
sashaice [31]
Bears are omnivores (and scavengers), meaning they eat both plants and animals.
it can be both a primary consumer (if it eats plants) and secondary & tertiary consumers (if it eats a plant-eating animal). so it depends on what it eats.

1. Calcium chloride is a salt that is added to roads and sidewalks
Sholpan [36]

Answer:

(d) In the presence of sulfuric acid, calcium chloride reacts to form hydrogen chloride.

Explanation:

It's because it lowers the melting point of the ice / etc so I think it is, but check it yourself too!

2H2 + O2 --> 2H2O can be classified as what type of reaction?
Sveta_85 [38]
Combustion reaction
Key: O2
O2 is normally in a chemical formula when you are used to burn anything, so basically, anything with O2 involves burning.

Which material is the lest likely to be recognized as a mixture by looking at it under a microscope ?
Lisa [10]
Hello,

The answer is option C <span>homogeneous mixture.

Reason:

The answer is option C because you can find </span><span>homogeneous mixtures anywhere for example: Vinegar. Its not option A because suspension is usually in elements but as not a mixture. Its not option B because a colloid is a measurement tool that allows to make compounds (mixtures).Its also not option D because those type o mixtures are hard to find in extreme weather conditions.

If you need anymore help feel free to ask me!

Hope this helps!
