Answer:
Cl-
Explanation:
The equation of the reaction is;
H+(aq)+Cl-(aq)+H2O(l)→H3O+(aq)+Cl-(aq)
Lewis base refers to substances that can donate a lone pair of electrons(e.g OH^-, Cl^- etc) or a pair of nonbonding electrons.(eg NH3, H20 etc). A Lewis base is therefore an electron-pair donor. They are easily recognized because they often have lone pairs or are negatively charged species.
If we look at the products, Cl- is a Lewis base because it is a lone pair donor. We see this more clearly because the specie is negatively charged.
Answer:
Explanation:
According to the ideal gas law equation:
Let's express the number of moles in terms of mass and molar mass:
Let's divide both sides by volume:
Notice that:
So the equation becomes:
Expressing density:
Substituting the given values:
Answer: Calculate the mass of nitrogen dioxide gas that would occupy the same volume as 10g of hydrogen gas at same temperature and pressure.(H = 1.0, N = 14.0, o = 16.0)
Answer:
The term dielectric makes reference to materials that are insulators (the charges in the material does not flow freely and for this reason an insulator material cannot conduce electricity). BUT if we applied this material in an electric field they can be polarized.
Dielectric Constant: It is also defined as a relative permittivity and it is the amount of charge required to produce one unit of electric flux( electric field in a surface) in a given medium.
it is typically denoted as Epsilon (ε)
and its formula is: ε = ε(ω) /ε(0)
where:
ε(ω) = the frequency-dependent permittivity of the material
ε(0) = the dielectric constant value in vacuum
Dielectric Constant values:
- For vacuum is always 1
- for water depending on the temperature can be 87.9 at 0º C, 80.2 at 20º C and 55.5 at 100º C.
Silver is not a compound. It's a mixture
