The heat of the flame comes to the sauce pan by radiation of infrared energy. The heat is conducted through the metal of the sauce pan. Now, with water in the sauce pan, convection works. Convection brings the cold water to the hot surface of the hot sauce pan. Once when there is only hot water in the sauce pan, the water will boil.
A solution is the answer to a problem
King Tut's reign came to an end at 3350 years ago
<h3>Further explanation</h3>
Carbon-14 is a radioactive isotope that can decay. This isotope can be used to determine how long ago an organism died by knowing the ratio from 12C to 14C
Can be formulated
Or we can use :
The half-life of C-14, 5730 years, so the decay constant :
Assume the initial C-14 activity was 13.6 disintegrations/min/g of C
Answer:
Molarity of solution = 0.9 M
Explanation:
Given data:
Moles of ZnCl₂ = 4.50 mol
Volume of solution = 200 mL
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Now we will convert the volume in L.
200 mL×1 L/1000 mL = 0.2L
M = 4.50 mol / 0.2 L
M = 0.9 M
