Answer:
E)Li
Explanation:
Electronegativity is the tendency of an atom to attract a pair of bonding electrons. In the periodic table, electronegativity increases across the period and decrease down the group.
This means the element at the top of the group would have the highest electronegativity.
The correct option is;
E)Li
Answer:
The frequency will increase
Explanation:
- Wavelength and frequency are inversely related such that waves with longer wavelength tend to have lower frequency and those with shorter wavelength have higher frequency.
-
- For example, gamma rays have a shorter wavelength but high frequency while radio waves have longer wavelength but have a low frequency.
- The product of wavelength and frequency gives the speed of the wave.
- Velocity = frequency × wavelength
- Wavelength is measured in meters while frequency is measured in Hertz.
Answer:
Explanation:
We're given the following ions:
Hydrogen sulfide is a weak acid, so it only ionizes to ions to a very low extent. This means we would expect to see it in a molecular form in a net ionic equation rather than a dissociated form (hydrogen cations and sulfide anions). In each of these net ionic equations, we expect the three cations to displace hydrogen from hydrogen sulfide and form three precipitates.
Firstly, iron(II) displaces hydrogen forming iron(II) sulfide and acidic conditions:
Secondly, chromium(III) cation displaces hydrogen forming chromium(III) sulfide:
Thirdly, nickel(II) cation displaces hydrogen forming nickel sulfide:
