Answer: determines the age of sample Carbon-14 is used in radiocarbon dating and radiolabeling. Medically important, a radioactive isotope is carbon-14, which is used in a breath test to determine the ulcer-causing bacteria Heliobacter pylori

The radiocarbon age of a certain sample of unknown age can be determined by measuring its carbon 14 content and comparing the result to the carbon-14 activity in modern and background samples.

HNO2 + CaCO3 = H2CO3 + Ca(NO2)<br><br> Can someone please balance this equation?!?!
katen-ka-za [31]
Balanced equation

So we see from inspection that H is not balanced. And by balancing H we have to add 2(NO2) and 2H

So the balanced equation is;

2HNO2 + CaCO3 = H2CO3 + Ca(NO2)2

Any questions feel free to ask.

In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions
maks197457 [2]

Answer:

31.3 kJ/mol is the free energy, ΔG, for the overall reaction, A⇌D.

Explanation:

A⇌B, \Delta G_1 = 11.9 kJ/mol  ...[1]

B⇌C, \Delta G_2= -26.7 kJ/mol  ...[2]

C⇌D, \Delta G_3= 7.30 kJ/mol  ...[3]

A⇌D, \Delta G_4 = ?...[4]

[4] = [1] - [2] - [3]  (Using Hess's law)

\Delta G_4=\Delta G_1-(\Delta G_2+\Delta G_3)

=11.9 kJ/mol - (-26.7 kJ/mol+7.30 kJ/mol)

=\Delta G_4=31.3 kJ/mol

31.3 kJ/mol is the free energy, ΔG, for the overall reaction, A⇌D.
