Answer:

0.033 mol

Explanation:

1 faraday is require to  1 mol of electron

0.1 faraday is required for 0.1 mol of electron

3 mol of electron is required for 1 mole Al3+ to Al

0.1 mole of electron will therefore need ( 0.1 mol × 1 mol ) / 3 mol = 0.033 mol

djyliett [7]

Answer:

Explanation:

The change in enthalpy of a substance when heated is given by

ΔH = m x Csp x ΔT

so the enthalpy change is dependent on the specific heat , i.e its capactity to absorb heat, and is not influenced by factors such as being closer to the melting point, volume , potential energy or being a solid or liquid.

An x-ray has a wavelength
goldfiish [28.3K]

Answer:

C

Explanation:

For electromagnetic waves frequency X wavelength = speed of light

                                                f * 2.2 x 10^-11  = 3 x 10^8  m/s

                                         f = 3 x 10^8 / 2.2 x 10^-11

                                            = 1.36 x 10 ^19

                                             = 1.4 x 10^19   with two significant digits
