Why is it important to have long term measurements when studying ecosystems

Chemistry

Because ecosystems don't change over one day, they change over a long period of time. Plus, something that happens may be because of more than just one change.

A 0.0200 M NaCl solution was formed when 38.0 grams of NaCl was dissolved in
satela [25.4K]

Answer: The volume of the solution formed will be 32.5 L. Explanation: Molarity is defined as the amount of solute present in 1 L of solution. The equation used to determine molarity of the solution follows: We are given: Molarity of the solution = 0.02 mol/L Mass of NaCl = 38 grams Molar mass of NaCl = 58.5 g/mol Putting values in above equation, we get: Hence, the volume of the solution formed will be 32.5 L.

How many grams of NH3 can be produced from 2.30 mol of N2 and excess H2.
MrRa [10]
<h3>Answer:</h3>

78.34 g

<h3>Explanation:</h3>

From the question we are given;

Moles of Nitrogen gas as 2.3 moles

we are required to calculate the mass of NH₃ that may be reproduced.

<h3>Step 1: Writing the balanced equation for the reaction </h3>

The Balanced equation for the reaction is;

   N₂(g) + 3H₂(g) → 2NH₃(g)

<h3>Step 2: Calculating the number of moles of NH₃</h3>

From the equation 1 mole of nitrogen gas reacts to produce 2 moles of NH₃

Therefore, the mole ratio of N₂ to NH₃ is 1 : 2

Thus, Moles of NH₃ = Moles of N₂ × 2

                                  = 2.3 moles × 2

                                  = 4.6 moles

<h3>Step 3: Calculating the mass of ammonia produced </h3>

Mass = Moles × molar mass

Molar mass of ammonia gas = 17.031 g/mol

Therefore;

Mass = 4.6 moles × 17.031 g/mol

         = 78.3426 g

         = 78.34 g

Thus, the mass of NH₃ produced is 78.34 g
