Answer:
stone and gold is my impermeable
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
Answer:
sodium ions and chloride ions
chloride ion
sodium ion
Explanation:
Ionic substances are composed of ions. When you dissolve an Ionic substance in water, the ions that compose the substance together with water molecules are present in solution.
Hence, when sodium chloride is dissolved in water, sodium ions and chloride ions are released in solution.
Water has a dipole moment. Hence, the chloride ions are attracted to hydrogen (the positive end of the dipole) while sodium ions are attracted to oxygen (the negative end of the dipole).
This is how the solid is dissolved in water.
The answer is B.) Energy directly from the sun to both producers and consumers.
