Consider the following elementary reaction:
Fudgin [204]

Explanation:

The equation is given as;

N2O(g) ⇄ N2(g) +  O(g)

k₁ = Forward reaction

k₋₁ = Reverse Reaction

Equilibrium concentration (K) = k₁ / k₋₁

K = \frac{[N2O] }{[N2] [ O]}

Find the elements sodium, oxygen, and phosphorus on the periodic table. Describe the monoatomic ions each would form. Then, give
miskamm [114]
Sodium would form Na+

Oxygen would form O-2

Phosphorus would form -3 or +5

Sodium and oxygen would combine to form ionic bonds because one is a metal and the other is non-metal, while Phosporus and oxygen would combine to form covalent bonds because they are both non-metals.

What material makes up ash and pumice?
slamgirl [31]

Pumice rocks are formed due to the air that is trapped in between the rocks, a body of magma spurting out with dissolved gas under pressure. As the magma cracks through the Earth’s surface, the sudden pressure drop causes the gas to come out of the solution. The flash of gas form the vent slices the magma and blows it out as a molten lather. The lather hastily solidifies as it flies into the air and falls back to Earth as pieces of pumice.

Luda [366]
The last one is the correct answer. The atomic structure can be broken down which is what the findings concerning protons, electrons and neutrons showed. The theory was thus modified. What remained was no chemical reaction could affect the basic structure of an atom.

Still the last choice is still true. The first choice is your second best answer because of what I wrote in the last sentence of the above paragraph.

H=1.01
meriva

Answer:

Molality of solution=10.11 m

Explanation:

We are given that

Given mass of KCl(WB)=75.3 g

Given mass of water (WA)=100 g=100/1000=0.1 kg

1 kg=1000 g

Molar mass of H=1.01 g

Molar mass of K=39g

Molar mass of Cl=35.45 g

We have to find the molality of a solution.

Molar mass of KCl(MB)=39+35.45

Molar mass of KCl(MB) =74.45 g

Number of moles of solute (KCl)=\frac{given\;mass}{molar\;mass}=\frac{W_B}{M_B}

Number of moles of solute (KCl)=\frac{75.3}{74.45}

Number of moles of solute (KCl)=1.011 moles

Molality of solution

=\frac{number\;of\;moles\;of\;solute}{mass\;of\;solvent}

Using the formula

Molality of solution=\frac{1.011}{0.1}

Molality of solution=10.11 m
