Answer:
K ^+ , CO3 ^2-
Explanation:
The compound is potassium trioxocarbonate(IV).
It contains cation (potassium ion) and acid radical ( trioxocarbonate (IV) ion).
Since K is in group 1 of the periodic table, it loses one electron to form ion i.e K^1. trioxocarbonate IV ion has a charge of 2-.and so the ions of the compound are as shown in the answer above.
Answer:
0.2mol/kg
Explanation:
molality is the concentration of a solution in moles of solute per kilogram of solvent
moles of solute (NaOH) = 2moles
mass of solvent in kg. =10kg
Therefore molality. = 2moles/10 kg
=0.2mol/kg

The source of the forces that move the tectonic plates along this plate
boundary is the convection current in the mantle. Hence, the correct
option in option (B)
<h3>What are Tectonic plates ?</h3>
Tectonic plates refers to the Spheres that are found in the uppermost Mantle of the Earth .
The Tectonic plates are also called the Litosphere .
The Motion of the Plates about the axis causes the Tectonic demarcations which are Know as the
Convergent
Divergent
Transform
Now these Plate are formed by the Convection of Currents in the Earths's Mantle
That is, the Dynamics of Current in and around the Earths Mantle brings about the tectonic plates
Hence the the correct option in option (B)
