Certain parts of the world don't have enough fresh drinking water. one possible solution is to tow icebergs from antarctica and melt them as needed. if 6.10 ✕ 1011 kj of energy were needed to melt an iceberg, how much did the iceberg weigh? the enthalpy of fusion (melting or freezing) for ice is 6.01 kj/mol, and 1 metric ton = 1,000 kg. metric tons

Idon't really understand this can you me and show your work.☺☺[ chemistry b] subject [ electron transfer in lonic bonds]grade( 12)

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.

Select the statement that describe chemical properties a. antacid tablets neutralize stomach acid b. helium is the lightest monatomic element c. water freezes at 0 celsius d. mercury is liquid at room temperature
