We can find the mass of ammonia using the ideal gas law equation,
PV = nRT
where
P - pressure - 2.15 atm x 101 325 = 2.18 x 10⁵
V - volume - 3.00 x 10⁻³ m³
n - number of moles
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature in kelvin - 15.0 °C + 273 = 288 K
substituting these values in the equation
2.18 x 10⁵ Pa x 3.00 x 10⁻³ m³ = n x 8.314 Jmol⁻¹K⁻¹ x 288 K
n = 0.273 mol
number of moles of NH₃ is 0.273 mol
molar mass of NH₃ - 17.0 g/mol
mass pf ammonia present - 0.273 mol x 17.0 g/mol = 4.64 g
mass of NH₃ present is 4.64 g
Answer:
El rendimiento de tubérculos de la papa es vulnerable a las altas temperaturas y se ve desafiado por el aumento asimétrico de las temperaturas diurnas y nocturnas. Este estudio tuvo como objetivo evaluar la fotosíntesis, el crecimiento de biomasa, la distribución de la masa de tubérculos y el rendimiento de tubérculo seco en papas cosechadas temprano que se cultivaron en el campo bajo condiciones de alta temperatura diurna y nocturna durante diferentes etapas de crecimiento.
If a biodegradable plastic or bioplastic ends up in a landfill site it will never decompose. In landfill sites waste is essentially mummified, in a complete absence of light and oxygen. Food that has ended up in landfill will not biodegrade, so there is no hope for biodegradable plastics or even bioplastics.So it is bad.
<span>The mass of the nail would increase, because the iron is adding oxygen to its chemical composition. This would increase the overall mass. If the mass increases from 23.2g to 24.1g, then the increase would be the difference between the two masses, or 0.9g.</span>
