The balanced, net ionic equation for the reaction shown as follows; Ba(NO2(aq) + Na2SO4(ag) = 2NaNO3 (ag) + BaSO4(s) is Ba2+ + SO42- → BaSO4 (s) (option B).

<h3>What is ionic equation?</h3>

Ionic equation is a reaction that involves ions that dissociated from the ionic compounds involved in the reaction.

In solution, some ions will participate in a chemical reaction (e.g. forming a precipitate) while others will remain in solution, unchanged. These ions that are unchanged in a reaction are called spectator ions.

However, it is useful to remove these spectator ions from chemical equations and just write equations with the species that actually react. These are called net ionic equations.

According to this question, the following chemical reaction is given: Ba(NO2(aq) + Na2SO4(ag) = 2NaNO3 (ag) + BaSO4(s)

The net ionic equation after removing the spectator ions is as follows: Ba2+ + SO42- → BaSO4

The solubility of barium chromate, bacro4, is 2.81 × 10−3 g/l. calculate the solubility product of this compound.

Anastaziya [24]

Solubility product constants are values to describe the saturation of ionic compounds with low solubility. A saturated solution is when there is a dynamic equilibrium between the solute dissolved, the dissociated ions, the undissolved and the compound. It is calculated from the product of the ion concentration in the solution. For barium chromate, the dissociation would be as follows:

BaCrO4 = Ba^2+ + (CrO4)^2-

So, the expression for the solubility product would be:

Ksp = [Ba^2+] [(CrO4)^2-]

we let x = [BaCrO4] = [Ba2+] = [(CrO4)2-] = 2.81x10^-3 g/L ( 1 mol / 253.35 g ) = 1.11x10^-5

Ksp = x(x)
Ksp= x^2
Ksp = (1.11x10^-5)^2
Ksp = 1.23x10^-10

The Ksp of Barium chromate at that same temperature for the solubility would be 1.23x10^-10.

Which of the following statements is not true of the process of nuclear fission? A.It is the process used in most nuclear power

Nady [450]

The statement in option B is not correct. B is the correct answer. This is because nuclear fission usually occur in large unstable isotopes, which are bombarded with high speed particles like neutrons, which make them to split into smaller particles. The statement in option A, C and D are true about nuclear fission.

What rate of reaction can be measured in the dark by determining the amount of oxygen gas consumed in a period of time?

Hatshy [7]

The rate of reaction that can be measured in the dark by determining the amount of oxygen gas consumed in a period of time is the rate of respiration.

Why?

Plants can undergo two types of reactions involving oxygen:

<u>Photosynthesis: </u>In this type of reaction, plants use energy from light to synthesize glucose. The chemical reaction for photosynthesis is: 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂, and this reaction produces oxygen gas in the presence of light, that means that to measure the rate of photsynthesis, you'll need to measure the amount of oxgen gas <u>produced</u> in a period of time.
<u>Respiration:</u> In this type of reaction, plants convert the energy stored in the chemical bonds of molecules such as glucose to obtain energy. The chemical reaction for respiration is: C₆H₁₂O + 6O₂ → 6H₂O + 6CO₂, since this reaction consumes oxygen gas in the dark, that means that to measure the rate of respiration, you'll need to measure the amount of oxygen gas <u>consumed</u> in a period of time.

Have a nice day!

Answer:

273k

Explanation:

Soooo... This is a complicated problem.

I dunno. Like... Is this a trick question? Trivia, maybe?

Nahhhhh...

It's just not telling us facts...SOME facts, but we need to use past learning to help us.

FIRST of all, what the heck does K even mean?

Is this a memo? A demo? A KO?

Okay, it's nither of these things.

So, let me tell you what the "K" means.

The K means "Kelvin" which is basically a word form for "-"

I AM NOT MAKING A FACE. IT'S THE WORD FORM FOR MINUS. STOP LAUGHING!!!!

And so... To bring objects to a COMPLEETE SKRRRRRRRRRRRRRRRRRRRRRRT...

It will need to be -273.

This means that the answer is 273k.

Which reminds me, Ima play 2k.

And ima rap to-day.

And now I'm being lame.

Just answer the question :/
