Mass of CO₂ evolved : 0.108 g
<h3>Further explanation</h3>
Given
1.205g sample, 36% MgCO3 and 44% K2CO3
Required
mass of CO2
Solution
0.36 x 1.205 g=0.4338 g
mass C in MgCO₃(MW MgCO₃=84 g/mol, Ar C = 12/gmol)
= (12/84) x 0.4338
= 0.062 g
0.44 x 1.205 g = 0.5302 g
Mass C in K₂CO₃(MW=138 g/mol) :
= (12/138) x 0.5302
= 0.046 g
Total mass Of CO₂ :
= 0.062 + 0.046
= 0.108 g

Answer:
High melting point,High density,Nonreactive
Explanation:
The following are the Properties of transition elements:
They have large charge/radius ratio. They are harder and they have high densities;.They have high melting and boiling points.They form compounds which are paramagnetic. They show variable oxidation states. They form colored ions and compounds. Compounds are formed with profound catalytic activity. Stable complexes are formed by them.
When Comparing with the alkali metals present in group 1 and the alkaline Earth metals that are present in group 2, the transition metals are considered to be much less reactive. They do not react fast with water or oxygen, which contributes to their resistance to corrosion.
The currents of the mantle pull the crust above it through drag. The plates, therefore, move on top of the mantle. At San Andreas fault, the North American Plate met the Pacific plate. However, due to the presence of the Farallon plate that was disappearing into the mantle in a subduction zone, the Pacific and North American plates movements changed in their configuration. The two plates now move past each other. The San Andreas fault is, therefore, a strike-slip fault.
