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 is bonding all about in chemistry?
Alina [70]
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.

What is the freezing point of a solution prepared from 45.0 g ethylene glycol (C2H6O2) and 85.0 g H2O? Kf of water is 1.86°C/m.
Andrews [41]

Answer:

T_{sol}=-15.9\°C

Explanation:

Hello,

In this case, we can analyze the colligative property of solutions - freezing point depression - for the formed solution when ethylene glycol mixes with water. Thus, since water freezes at 0 °C, we can compute the freezing point of the solution as shown below:

T_{sol}=T_{water}-i*m*Kf

Whereas the van't Hoff factor for this solute is 1 as it is nonionizing and the molality is:

m=\frac{mol_{solute}}{kg\ of\ water}=\frac{45.0g*\frac{1mol}{62g} }{85.0g*\frac{1kg}{1000g} } =8.54m

Thus, we obtain:

T_{sol}=0\°C+(-8.54m*1.86\frac{\°C}{m} )\\\\T_{sol}=-15.9\°C

Best regards.

SOMEONE PLEASE HELP ME WITH THIS QUESTION!!!!!!!!!!!!
Advocard [28]

Answer:

KOH

Explanation:

Chemical reaction:

2K + 2H₂O →  2KOH + H₂

Element ratio of K.

K = 1

Because only potassium is present.

Element ratio of H₂O.

2 : 1

in water ratio of element is 2 : 1 because two hydrogen and one oxygen atom present.

Element ratio of KOH

1 : 1 : 1

in KOH elemental ratio is 1 : 1 : 1 because one potassium one hydrogen and one oxygen atom are present.

Element ratio of H₂.

2

Just two atoms of hydrogen are present.
