Explanation:
The shortest bond distance is at N2 due to its high bond order of 3. From N2 to F2 the bond distance increases despite the fact that atomic radius decreases.
H₂ is the diatomic molecule or ion that has the shortest bond length.
What are diatomic molecules?
Diatomic atoms are those atoms which are composed of two atoms that are joined by a chemical bond.
H₂ is the simplest diatomic molecule is this.
It is diamagnetic and has only two molecular orbitals (g and u), two electrons, and a bond order of one.
It has a 74 pm bond length.

what causes the outer layer of star to expand?
Answer/Explanation:
Stars spend the majority of their lifespan medling hydrogen nuclei together to form helium. When the hydrogen that in the core of the star begins to run out, the star will start using hydrogen away from its core and this is what causes the star's outer layer to expand and slowly cool down.

Make sure to reword this in your words!!!As consumption of a synthetic material increases, the associated negative impacts to Earth required to produce the material increase.
Is this a true or false question? If so, then this would be a true statement. Synthetic materials are made in factories, and the usage of factories increases the risks of harmful gases and chemicals that negatively impacts Earth.
It is generally true that as consumption of a synthetic material increases, the associated negative impacts to Earth needed to produce the material also increase.
Why the given sentence is true?This is because the production of synthetic materials often requires the extraction and processing of non-renewable resources, such as petroleum, which can have a range of negative environmental impacts, including habitat destruction, air and water pollution, and greenhouse gas emissions.
Additionally, the disposal of synthetic materials can also lead to environmental problems, such as the accumulation of non-biodegradable waste in landfills and oceans.
However, it is important to note that not all synthetic materials have the same environmental impacts, and some materials may be more sustainable than others depending on their production methods and intended use. Hence, the given sentence is true.

With the European Climate Law, the EU committing to carbon neutrality by 2050. What does that mean in practice?
Climate change is already affecting the entire world, with extreme weather conditions such as drought, heat waves, heavy rain, floods and landslides becoming more frequent, including in Europe. Other consequences of the rapidly changing climate include rising sea levels, ocean acidification and loss of biodiversity.
In order to limit global warming to 1.5 degrees Celsius – a threshold the Intergovernmental Panel for Climate Change (IPCC) suggests is safe – carbon neutrality by mid-21st century is essential. This target is also laid down in the Paris agreement signed by 195 countries, including the EU.
In December 2019, the European Commission presented the European Green Deal, its flagship plan that aims to make Europe climate neutral by 2050. This target will be reached through the European Climate Law that sets climate neutrality into binding EU legislation.

What is the ph of the solution formed by mixing 25. 0 ml of a 0. 15 m solution of nh3 with 25. 0 ml of 0. 12 m hcl? (kb for nh3 = 1. 8 10–5 )
Answer:
Explanation:
the answer is 8.66
Mark me brainliest please.
The pH of the solution formed by mixing 25. 0 ml of a 0. 15 m solution of NH₃ with 25. 0 ml of 0. 12 m HCl is 8.66.
What is pH?pH is potential hydrogen. It is the measurement of the acidity and basicity of any solution.
The solution of NH₃ is 25. 0 ml of a 0. 15 m
The solution of HCl is 25. 0 ml of 0. 12 m hcl
The pkb value is [tex]1.8 \times 10^-^5[/tex]
Putting the value in the formula
[tex]pOH=pKb +log[NH_3][HCl]\\\\ pOH = 1.8 \times 10^-^5+ log \dfrac{25.0 \times 0.15}{ 25.0 \times 0.12} \\\\ pOH = 1.8\times10^-^5+ log1.25 \\\\pOH = 1.8\times 10^-^5 + 1.25 = 3.05\\\\ pH = 14 - pOH = 14 - 1.25 = 8.66[/tex]
Thus, the pH of the solution formed by mixing 25. 0 ml of a 0. 15 m solution of NH₃ with 25. 0 ml of 0. 12 m HCl is 8.66.
