Time passed Time passed 14C initially present 14C at end of half-life
(half life) (Years)

0 0 1,000,000 1,000,000
1 5750 ..... 5,00,000
2 11500 ..... 2,50,000
3 17250 ..... 1,25,000
4 23000 ..... 62,500
Since, wood sample contained 1/16 of current atmospheric concentration of 14C. It means that sample has crossed 4 half-life. Number atoms left are 4 half life = 62,500
I think the slant would be called the tilt

Answer:
The combustion of methane or octane is exothermic; it releases energy. CH4 + 2 O2 → CO2 + 2 H2O + energy The energies of the products are lower than the energiies of the reactants
Answer:
455.4 mmHg
Explanation:
To solve this problem we can use <em>Gay Lussac's Law</em>, which describe the temperature and pressure of a gas, at constant volume and composition:
In this case:
We <u>input the data</u>:
- 621 mmHg * 231 K = P₂ * 315 K
And <u>solve for P₂</u>:
