The distance at which the lowest potential energy is reached and the distance at which positive charges are least repellent are used to calculate bond length.
What do you mean by bond length?The distance between the centers of two covalently bonded atoms is referred to as the bond length. The quantity of bound electrons determines how long the bond will be (the bond order).
The attraction between the two atoms is stronger and the bond length is shorter the higher the bond order. The covalent radii of the two atoms are typically added together to determine the length of the connection between them.
Picometers are used to measure bond length. Consequently, bond length grows in the following order: Triple bonds are made up of two bonds and one bond.

If the total mass of reactants in a chemical reaction is 20g, what can we say about the total mass of products?.
If the total mass of reactants in a chemical reaction is 20 g, we can say that the total mass of the products formed in a reaction is 20g.
The law of conservation of mass states that mass cannot be created, nor to be destroyed. It can be converted from one form to the another form. In other words, we can say that the mass of the reactant is equal to the mass of the product. For example, the reaction between 12 g of H₂ and 8 g of O₂ forms 20 g of H₂O. Its balanced reaction is given as
2H₂(8g)+O₂(12g)→2H₂O(20g)
In the above reaction, 8g of hydrogen when reacts with 12 g of oxygen forms 20 g of water as a product. No loss in the mass is observed in the reaction when it is completed.
Therefore, if the total mass of reactants in a chemical reaction is 20 g, we can say that the total mass of the products formed in a reaction is 20g.

The volume of the reaction mixture at stp after the reaction goes to completion is 700 ml.
What is limiting reagent?
Reagents that are fully consumed during the course of a chemical reaction are known as limiting reagents. They might also be referred to as limiting reactants or agents. The stoichiometry of chemical processes states that a specific number of reactants must be present for the reaction to be completed.
2NO(g) + O2(g) gives 2NO2 (g)
presently, 400 ml of NO = 2 mol of NO2 + 2 mol of NO equals 400 ml of NO2
500 ml of O2 + 2 mol of NO2 + 1 mol of O2
= 1,000 ml NO2
Here, the limiting reagent is NO
as of right now, 400 ml of NO2 = 1 mol of O2 + 2 mol of NO
= 200 ml
500 ml total is divided by that by 200 ml, for a total of 300 ml.
The reaction mixture's total volume is 1000 ml, which is reduced by 300 ml to give 700 ml.

How do you find the molar mass of ammonia?.
The molar mass of ammonia can be find by adding the atomic mass of hydrogen and nitrogen. Molar mass is twice of the atomicity of the compound.
The molar mass is defined as an average of many instances of the compound, which often vary in terms of mass due to the presence of isotopes
We know that ammonia is compound which is made up of nitrogen and hydrogen.
It contains single atom of nitrogen and 3 atoms of hydrogen.
Molecular formula of ammonia is NH₃
So, molar mass of nitrogen =atomic mass of nitrogen +atomic mass of hydrogen
We know that atomic mass of nitrogen is 14 a.m.u where atomic mass of hydrogen is 1 a.m.u

Answer:
O: 1s2 2s2 2p4
Explanation:
when the pressure of a gas phase reaction at equilibrium decreases, in which direction does the equilibrium shift?
As pressure rises, the equilibrium will move to the side of the reaction where there are less moles of gas. When the pressure drops, the equilibrium will move to the side of the process where there are more gas molecules.
Which way does the equilibrium move when the reaction pressure at the equilibrium decreases?According to Le Chatelier's principle, a pressure change will cause an equilibrium to shift to the reaction's side that has the fewest moles of gas, while a pressure change will cause it to shift to the reaction's side that has the most moles of gas.
Pressure reduction shifts the equilibrium to the side with the majority of molecules. This lessens the effects of the change because as the number of molecules increases, so does the pressure.

Why does the cheese curds form?We need to review the fundamental nature of the milk and the lemon juice. In this case, it must occur to us again that milk is made up of a protein and since it is a protein, we know that there is an optimum pH where a protein is able to function quite well. Outside that pH, the protein may not be able to function well.
Again the lemon juice is largely composed of acid since it is of the citrus family hence it contains the citric acid and this would cause the pH of the system to ow tilt towards the acid range.

calculate the number of grams of aluminum required to prepare 297.0 g of chromium metal by the first reaction.
To prepare 297.0g of chromium we need 154.21g of aluminum.
The preparation of chromium using aluminum powder is an exothermic process. It is the reaction where heat is released during the formation of product.
Therefore, the chemical reaction for the formation of chromium is:
Cr2O3(s) + 2Al(s) -> 2CrO(s) + Al2O3(s)
Here, we can see that 2 moles of aluminum produces 2 moles of chromium.
Hence,
Molar mass of aluminum = 27g
as 2 moles of aluminum is required then 2 x 27 = 54g.
Molar mass of chromium = 54g
As, 2 moles of chromium is obtained then 2 x 54 = 104g.
Therefore, by cross multiplying we get the amount of aluminum required,
mass of aluminum produced = 54 x 297.9/ 104
= 16038/104 = 154,21g.
Therefore, the required amount of aluminum is 154.21g

Restricting oxygen by keeping air from reaching the fire's center so that the combustion process can lower the amount of oxygen in the enclosed space until the fire extinguishes itself. The foam smothers the flames by covering the fuel surface. The foam covering keeps the fuel surface and the flames/ignition source apart. Foam cools the fuel as well as any nearby metal surfaces.

The net entropy change in two reservoirs is 1/12 kj/K
The second law of thermodynamics states that an increase or decrease in the system's entropy depends on whether heat is accepted into or rejected out of it.
Here, Temperature of source, T- 1200K;
Temperature of sink, T000K; heat rejected by source-heat accepted by the sink=Q=100kJ;
Decrease in entropy of the source,
ΔS source = Q / T source = 100/ 1200 = 1/12 kj/K.
Increase in entropy of the sink,
Δ S sink = Q/ T sink = 100/ 600 = 1/6 kj/K.

How does the volume of a real gas compare to the volume of an ideal gas at high pressure?.
According to the Kinetic theory of gases, the volume of ideal gases is negligible compared to the volume of the container. Whereas, the volume of real gases cannot be neglected.
What is kinetic theory of gases?According to the Kinetic theory of gases, matter is made of tiny particles. These particles are not exerting any intermolecular force of attraction or repulsion.
The gaseous particles exerts a pressure by collision to other particle and with the wall of the container. At high pressure, as per Boyle's law for ideal gases, the volume of the gases decreases.
However, Boyle's law cannot be applicable to real gases at all temperature. As the temperature increases, the volume also increases. Moreover, when the volume of particles is reduced, they haven't enough space to move.
Therefore, at lower volume, particles definitely experience an intermolecular force of attraction or repulsion. But this is not considered in the ideal gas theory.
