Answer:
Balanced.
Explanation:
Both sides are pulling with equal force.
Answer:
48889 years
Explanation:
Activity of the living sample Ao= 15.2 disintegration per minute
Activity of the cloth A= 8.4 disintegration per minute
Half life of 14C= 5715 years
Time taken for the decay t= the unknown
From;
0.693/5715 = 2.303/t log (15.2/8.4)
1.213 × 10^-4 = 2.303/t log (1.8095)
1.213 × 10^-4 = 0.593/t
t= 0.593/1.213 × 10^-4
t= 4888.7 years
t= 48889 years
Answer:
The molarity of the solution is 4M
Explanation:
Molarity is defined as the amount of moles of solute present in one liter of solution. So the molarity of any solution can be found by dividing the moles of solute between the volume in liters of the solution.
For this case we have:
Orbitals am only hold two electrons each, so 3 orbitals can hold 6 electrons
Drawbacks of Dalton's Atomic Theory. The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects.
