<span>This is the process of radioactive dating. Carbon is used because it is an essential part of all living organisms and has a radioisotope that decays with a half-life of 5000 years. This ratio makes it easy to date an object using Carbon-14. Uranium is used for objects that have a much longer half-life, outside the bounds of carbon's abilities.</span>
Answer:
6. C3H2O
Explanation:
C= 12.0107; H= 1.00797; O=15.9994
We calculate:
C= 65.85/12.01=5.48
H= 4.91/1.00=4.91
O=29.24/16.00= 1.82
Later, we divide among the smaller quantity
C=5.48/1.82= 3.01
H=4.91/1.82= 2.70
O=1.82/1.82=1
Answer:
is the symbol for an oxide ion
Answer:
83 mL
Explanation:
Use the dilution equation M1V1 = M2V2
M1 = 18 M
V1 = ?
M2 = 6.0 M
M2 = 250 mL
Solve for V1 --> V1 = M2V2/M1
V1 = (6.0 M)(250 mL) / (18 M) = 83 mL
Answer:
The Water Displacement method
