Answer:
A I believe this is the answer I do not know look at the picture I attached
It’s b . The magnesium will dissolve and the copper will be deposited
Molar mass of N = 14 g/molMolar mass of O2 = 32 g/molAdding both masses = 46 g/molActual molar mass/ Empirical molar mass = 138.02 / 46 = 3Now multiplying this co effecient with empirical fomula NO2 = 3(NO2) = N3O6So according to above explanation,D) N3O6, is the correct answer.
Production of materials and transportation are the examples of three carbon emission.
Extraction and production of purchased materials and transportation of purchased fuels are the examples of three carbon emission. Scope 3 emissions refers to all indirect emissions that occur in the chain of the reporting company that is included in both upstream and downstream emissions.
Big machineries are used for the production and extraction of materials as well as the transportation requires fossil fuels for working which releases carbondioxide gas in the atmosphere so we can conclude that production of materials and transportation are the examples of three carbon emission.
Answer:
2.28 M
Explanation:
Step 1: Given data
Percent by mass (%m/m): 20.0 %
Density (ρ): 1.114 g/mL
Step 2: Calculate the percent by volume (%m/v)
We will use the following expression.
Step 3: Calculate the moles of solute in 100 mL of solution
The molar mass of phosphoric acid is 97.99 g/mol. The moles corresponding to 22.3 g are:
Step 4: Calculate the molarity of the solution
0.228 moles of solute are in 100 mL (0.100 L) of solution. The molarity of the solution is:
