Answer:
I would say C)Selenium because it has a closer amount of valence electrons in the atom but I could be wrong as well no one is perfect. If that's not the answer then ask for some help by the teacher it's likely that you'll get the most help there
Data analysis has two prominent methods: qualitative research and quantitative research. Each method has their own techniques. Interviews and observations are forms of qualitative research, while experiments and surveys are quantitative research.
Answer:
The structure for 2 brormocyclopentan amine is given in attached file.
Explanation:
2-bromocyclopentamine (Figure attached) is a synthetic compound which is synthesized by substitution reaction of cyclopentamine and hydrobromide. Its molecular formula and molecular mass are C5H10NBr and 164.05 g/mol respectively. It is a very reactive compound so it doesn’t available in pure form, it is present in market as a mixture of 2-bromocyclopentamine and Hydrobromide.
Properties:
Its boiling point is 115 °C.
Its melting point is -75 °C.
It is highly flammable.
It is highly toxic.

The answer to this question is C.
Answer:
Explanation:
Hydrogen peroxide is a chemical compound with the formula H₂O₂. In its pure form, it is a very pale blue liquid, slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic. Concentrated hydrogen peroxide, or "high-test peroxide", is a reactive oxygen species and has been used as a propellant in rocketry. Its chemistry is dominated by the nature of its unstable peroxide bond.
Chemical formula: H2O2
Density: 1.45 g/cm³
Boiling point: 302.36°F (150.20°C)
Average Molar mass: 34.01 g/mol
Melting point: 31.23°F (-0.43°C)
Legal status: Over-the-counter drug · Not evaluated by FDA
Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H₂O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. Two hydrogen atoms are attached to one oxygen atom at an angle of 104.45°.
Boiling point: 212°F (100°C)
Melting point: 32°F (0°C)
Chemical formula: H2O
Average Molar mass: 18.02 g/mol

So probably C or D i dont know
Sorry if it is wrong
Answer:
ExplanatioHydrogen cannot exist in free state as hydrogen needs an electron to attain stability. If an element does not attain stability it cannot exist on its own. In Sun there are large number hydrogen atoms and helium atoms present this creates a lot of energy and nuclear fusions are occured. Gases that attain stability can normally exist on their own. E.g. Argon, Neon, Helium, Krypton and Xenon. Gases that cannot exist on their own are:
H2
O2
N2
Hope it helped a little......
a substance that donates electrons to form a covalent bond
a substance that accepts electrons to form a covalent bond
a substance that when dissolved in water increases hydrogen ion concentration
The definition of a Lewis base is: C. a substance that accepts electrons to form a covalent bond.
What is a Lewis base?
A Lewis base can be defined as a specie of an ionic or chemical compound that contains an empty orbital which allows it to donate an electron pair (two or more electrons) to form a covalent bond.
This ultimately implies that, a Lewis base is a chemical substance that accepts an electron pair (two or more electrons) to form a covalent bond.
In Chemistry, some examples of a Lewis base include the following:

Answer:
the definition is : a compound or ionic species which can donate an electron pair to an acceptor compound.
so as far as i know i know the answer is: a substance that accepts electrons to form a covalent bond.
