They can use carbon dating or lithium argon dating.
Answer:
C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + H₂O
Explanation:
When a forest burns and all that's left is some ash, most of the mass of the trees go to the atmosphere, in the form of carbon dioxide.
In a total combustion process of organic matter,<em> the two molecules produced are carbon dioxide and water. </em>(CO₂ and H₂O)
The equation for the combustion of glucose is:
C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + H₂O
Answer:
3grams
Explanation:
The reaction for the production of Magnesium dioxide will be
Mg + O2 → MgO
we have 5g of MgO (molar mass 40g)
no of moles of MgO = 5/40 = 0.125
Using unitary method we have
1 mole of Mg require 1 mole of MgO
0.125 Mole of MgO = 0.125mole of Mg
n = given mass /molar mass
0.125 = mass / molar mass
mass = 0.125* 24 = 3grams
