Displacement reaction
Because Al goes to SO4 and
Cu goes from SO4 to Cu
This happens because Al is more reactive (higher up in the reactivity series) than Cu
Answer:
The total pressure is 27.8 atm
Explanation:
From the ideal gas equation,
PV = nRT
P (total pressure) = nRT/V
n (total moles of gases) = (6/1 moles of hydrogen) + (15.2/14 moles of nitrogen) + (16.8/4 moles of helium) = 6+1.1+4.2 = 11.3 moles
R = 0.082057L.atm/gmol.K, T = 27°C = 27+273K = 300K, V = 10L
P = 11.3×0.082057×300/10 = 27.8 atm
Answer:
The sugar particles are so small that they have dissolved in the water, and can easily pass through the filter.
Planck suggested that light/energy was absorbed/released in certain amounts, called quanta.
