Which sentences describe ponds and lakes?
these are water bodies formed from melting glaciers. however, their size can vary from a few square meters to thousands of square kilometers. these regions form where freshwater streams or rivers merge with the ocean. they can be seasonal, existing for a few months, or exist for hundreds of years or more. you can find algae, fishes, sea urchins, octopuses, and starfish in them.

" However, their size can vary from a few square meters to thousands of square kilometers."

"They can be seasonal, existing for a few months, or exist for hundreds of years or more. "

Explanation:

the first sentence is incorrect, many places that don't even get snow or cold weather have ponds and lakes. You wont find sea urchins, octopuses or starfish in ponds and lakes. Many lakes are not connected to the ocean.

" However, their size can vary from a few square meters to thousands of square kilometers."

"They can be seasonal, existing for a few months, or exist for hundreds of years or more. "-

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
