After 17190 years, Carbon-14 will reach a mass of 15 grams.
Pi is your initial amount (120 grams)
0.5 as your exponential base represents your HALF life hence 0.5
t represents the time elapsed
c represents your given half life value of (5730)
P(t) represents the exponential function of your half life
120/2 =60
60/2 = 30
30 /2 = 15
As you can see above, 3 half lives of 5730 years EACH degraded the carbon-14 to 15 grams. You divide each number by two as it is a HALF life.
P(t)= Pi (0.5) ^t/c
P(17190) = 120 (0.5) ^17190/5730
P(17190) = 120 (0.5) ^3
P(17190) = 15 grams
So your answers should be 3 half lives or after 17190 years have elapsed!
Reaction between Calcium Nitrate and Sodium oxalate results in the formation of Sodium nitrate and Calcium Oxalate through Double displacement reaction.
<h3>What is Double displacement reaction ?</h3>
A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products.
Usually, a double displacement reaction results in precipitate formation.
The chemical bonds between the reactants may be either covalent or ionic.
Drawing representing the reaction that occurs between calcium nitrate and sodium oxalate is attached as figure.

Temperature: a measure of the average kinetic energy of particles in an object
heat: the total energy of any closed system, including all internal kinetic and potential energy of the system
thermal energy: something that flows into a substance
Answer:
A.
as the sum of the energy of the products and the energy of the reactants.
Explanation:
Because the sun is on top of the energy.
