The answer to your question would be sound because dogs have excellent hearing so when it hears loud thunder it was a frightened reaction
The balanced reaction that describes the decomposition of nitroglycerin to produce carbon dioxide, nitrogen, water and oxygen is expressed: <span>4c3h5(no3)3(l) = 12co2(g)+ 6n2(g) +10h2o(g) + o2(g). Hence for every 4 moles of nitroglycerin used, 12 moles of carbon dioxide is produced. When 25 grams of CO2 is produced, we convert this to mass and multiply by 4/12 and multiply again with the molar mass of nitroglycerin. The answer is 42.99 grams nitroglycerin.</span>
Matter can only me transformed, but not created or destroyed.
Answer:
151 g/mol
Explanation:
When a nonvolatile substance is added to a solvent, the freezing point of the solvent is changed, which is called cryoscopy. When temperature change can be calculated by:
ΔT = Kf*W
Where Kf is the molal freezing point constant of the solvent and W is the molality of the solution.
For cyclohexane, Kf = 20.2 °C/molal, and the freezing point is 6.4 °C, so:
6.4 - 1.05 = 20.2 * W
20.2W = 5.35
W = 0.26485 molal
The molality is:
W = m1/m2*M1
Where m1 is the mass of the solute (in g), m2 is the mass of the solvent (in kg), and M1 is the molar mass of the solute. So:
0.26485 = 2.00/0.05M1
0.0132425M1 = 2.00
M1 = 151 g/mol
Chlorine is used as a disinfectant to wastewater treatment
plants. The addition of chlorine to the final treated water is because to make
sure that some of the microorganisms not killed during treatment is eliminated.
It is consumed before it is released to the environment to ensure that
microorganisms and other marine life are not killed in the process too.
