According to reference table adv-10, which is the strongest reducing agent?

1 answer:

3 0

Li(s) (answer A)
Li is strongest reducing agent because of the lowest standard reduction potential. when something is oxidized, it reduces another substance, becoming a reducing.Hence Lithium is strongest reducing agent. Reducing agent is stronger when it has a more positive oxidation potential.

What do we call the amount of energy required to change from a liquid to a gas?

rewona [7]

Hello!

When something is a liquid then turns to a gas, this is known as evaporating so we would call it the heat of evaporation or also known as latent heat. Just remember liquid to gas is vapor!

I hope this helped!

I am, yours most sincerely,

Explain why the structure of Copper [ 1s², 2s², 2p⁶, 3s², 3p⁶, 3d¹⁰,4s¹] is more stable than [ 1s², 2s², 2p⁶, 3s, 3p²⁶, 3d⁹,4s²

Some oxygen gas takes up a volume of 2.00 liters at 0.99 atm and 273 K. Its volume doubles and its temperature decreases to 137

nataly862011 [7]

Answer:

The answer to your question is : letter B. 0.25 atm

Explanation:

To solve this problem we need to use the combined gas law:

P₁V₁ = P₂V₂

T₁ T₂

Data

P1 = 0.99 atm V1 = 2 l T1 = 273K

P2 = ? V2 = 4 l T2 = 137K

Now, the clear P2 from the equation and we get

P2 = P1V1T2 / T1V2

Substitution P2 = (2 x 0.99 x 137)/(273 x 4)

P2 = 271.26 / 1092

Result P2 = 0.248 atm ≈ 0.25 atm

We can use the formula. 

c1v1 =c2v2

Where c1 is the concentration and v1 is volume of the concentrated solution. 

c2 is the concentration

and v2 is the volume of the diluted solution to be prepared

9.00 M x V1 = 2.75 M x 350 mL

V1 = 106.9 mL

Volume of 106.9 mL from the concentrated solution should be taken and diluted to 350 mL.

What is the meaning of cryosphere

nikklg [1K]

Answer:

The part of the earth’s surface where, at temperatures below 32°F (0°C), the water is frozen solid. Even a small pond while frozen over during the winter is part of the cryosphere, but cryosphere refers more often to large regions covered in snow and ice for much or all of the year, as the ice sheets of Antarctica and Greenland, glaciers, icebergs, and expanses of permafrost, all of which are especially sensitive to global shifts in climate:
