What is the cation in the chemical formula MnSe?

Chemistry
1 answer:
sineoko [7]2 years ago
6 0

Answer:

Mn

Explanation:

The cation in the chemical formula MnSe is the Mn specie.

  • A cation is a positively charge ion or radical.
  • Such an ion has lost electrons and this leaves a net positive charge on them.
  • The Mn is the cation
  • Most metals forms cations as they readily lose electrons due to their large atomic radius.
  • Se is the anion as it will carry a negative charge
  • Most non-metals are anions

What does an increase in temperature do to the reaction rate?
Goshia [24]

Answer:

An increase in temperature typically increases the rate of reaction because an increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.

Sally has constructed a concentration cell to measure Ksp for MCln. She constructs the cell by adding 2 mL of 0.05 M M(NO3)n to
hram777 [196]

Answer:

0.1056 mole

Explanation:

As Sally knows that the charge on the metal ion is n = +2

$MCl_n=MCl_2$

In that compartment $[M^{n+}]=[m^{2+}]=8.279 \ M$

The volume of the $MCl_n$ taken in that compartment = 6.380 mL

So, the number of moles of $M^{2+} = 8.279 \times 6.380$

                                                      = 52.82 m mol

                                                      = 0.05280 mol

$MCl_n \rightarrow M^{n+}+nCl^-$

But n = 2

Therefore, moles of $Cl^-$ = 2 x moles of $M^{n+}$

                                       = 2 x 0.05282

                                       = 0.1056 mole
