Answer:
B sediment
Explanation:
The excess mileage leads to additional pollution. Car exhaust contains toxic gases, and car fluids often leak (oil drips, antifreeze leaks, etc...). The exhaust also contains nitrogen oxide, which can lead to nutrient-related problems in the environment.
You need to find the moles of CaCl, you can either do a grams to mol conversion, OR, you can do the equation used in A without the last step which was converting it into the grams on CaCl. You get .00848146 mol CaCl. with that you can find the concentration using the molarity equation which is M=mol/L. M=.000848146mol/3.98 L. M=0.000213 or your teacher may want you to write it 0.000213 M CaCl. Hope I helped :)
Answer:
135.0 g
Explanation:
the block read 100, 30, and 5 putting those together makes 135.00 g
Answer:
2, 2, 1
Explanation:
The coefficient of H₂O will be 2 because we have 2 oxygens on the right side but only one on the left side. Now, we have 4 hydrogens on the left side but only 2 on the right side. To balance, we'll add a 2 as the coefficient of H₂. We don't need to change the coefficient of O₂ because the equation is already balanced.
Final answer, 2, 2, 1.
