Which non silicate mineral has carbonate as a negatively charged complex ion?

1 answer:

6 0

Answer is: calcite and dolomite.
Non-silicate mineral is mineral that does not hold the silica tetrahedron. Carbonate anion is CO₃²⁻.
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO₃).
Dolomite is an carbonate mineral composed of calcium magnesium carbonate (CaMg(CO₃)₂).

Carbon-14 has a half-life of 5,700 years.

Maksim231197 [3]

Answer:

$3.106\ \text{g}$

Explanation:

$t_{1/2}$ = Half-life of carbon = 5700 years

t = Time at which the remaining mass is to be found = 10400 years

$m_0$ = Initial mass of carbon = 11 g

Decay constant is given by

$\lambda=\dfrac{\ln2}{t_{1/2}}$

Amount of mass remaining is given by

$m=m_0e^{-\lambda t}\\\Rightarrow m=m_0e^{-\dfrac{\ln2}{t_{1/2}} t}\\\Rightarrow m=11e^{-\dfrac{\ln 2}{5700}\times 10400}\\\Rightarrow m=3.106\ \text{g}$
