Answer:
The answer would be C. 1852.3
Explanation:
Answer:
Acids:
Bases:
Explanation:
According to the Bronsted-Lowry acid-base theory, an acid is a proton donor and a base is a proton acceptor. In this case, notice that donates a proton, since after it loses a proton, it becomes a chloride anion. Therefore, is a Bronsted acid.
Similarly, is a proton acceptor and, therefore, a Bronsted base, since it becomes .
If we look at the reverse reaction, chloride can gain a proton to become , meaning it's a conjugate base.
Finally, is a conjugate acid, since it can donate a proton to chloride.
40.6 kJ of heat energy had been emitted.
CO(g) + 2H2(g) CH3OH(l)CO volume, V (CO), equals 15 L or 0.015 m3.
Temperature = 85 0C = 85 + 273 = 358 K Pressure = 112 kPa = 112,000 PaPV = nRT n= 112000 0.015 / 8.314 358 n(CO) = 0.56 moles,
according to the ideal gas law.H2 volume is 14.4 L or 0.0144 m3
T = 750C + 273 K = 348 K n(H2) = 99191.84 0.0144 m3 / 8.314 348 K = 0.49 moles of H2 Pressure = 744 torr = 99191.84 Pa
Hydrogen is the limiting reagent, according to the calculation above.CH3OH = H2 = 0.49/2 = 0.245 m-238.6 (-110.5) = -128.1 kJ/mol for H(rxn) = H(f) (CH3OH) - H (rxn)
We must now multiply H(rxn) by the number of moles of methanol.
E = H(rxn) n(CH3OH) = 128.1 0.245 = 40.6 kJ.

I think the correct answer is option 3. CaCl2 is the compound that is an electrolyte when dissolved in water. An electrolyte is a substance that conducts electricity in solution. Calcium Chloride when in solution dissociates into ions which allows the flow of current in the solution.
The outer ear is responsible in carrying sound waves to the the tympanic membrane aka the eardrum, which vibrates when sound waves hit it.
