Answer:
E=hcλ or E=hν , where h is Planck's constant i.e, energy is directly proportional to frequency and inversely proportional to wavelength.
El ácido sulfúrico es un ácido fuerte y por eso disocia completamente. La concentración de H+ será igual a la concentración de ácido sulfúrico (0.000475 M).
Para encontrar el pH, calcula -log[H+] = -log(0.000475) = 3.323
Para encontrar el pOH, sabes que pH + pOH = 14, y por eso pOH = 14 - pH = 14 - 3.323 = 10.677.
Answer:
grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
Explanation:
The molecular weight of acetylene is 26.04 g/mol
Molecular weight of carbon is equal to 12.011 g/mol
Two carbon atom produces one acetylene molecule.
Thus, 2 * 12.011 g/mol of carbon is used to produce 26.04 g/mol of acetylene,
Amount of carbon required to produce 59.8 grams of acetylene
grams/mol
grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
