An ice cube when you heat it it can to water and water is liquid of course
328 % means 0.328 g of KCN in 100 g of solution
0.328 g of KCN ---------> 100 g of solution
1120 * 10^-3 g of KCN ------> (100 / 0.328) * 1120 * 10^-3
= 341 g of solution
Answer:
plankton
Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.
Explanation:
Final amount =initial anount *(1/2)^(t/half life)
final amount =2.000 mg *(1/2)^(10.5/5.20) = 0.493 mg remain after 10.5 years
