The complete question; At atmospheric pressure a balloon contains 2.00 l of nitrogen gas, how would the volume change if the kelvin temperature was only 75 % of its original value?
The change in volume would be;
original volume × percentage
= 2 ×0.75 = 1.5 L
Thus the volume would change by 1.5 L
Answer:
A
Explanation:
Surface water percolates downwards to join the aquifer or the water table ultimately forming ground water
Answer:
a) 0.000273 mol /L
b) 0.000244 mol/L
c) 0.0001044 mole
Explanation:
The partial pressure of oxygen in the atmosphere =
1 atm % of atm O2 atm
a) Solubility mole / L
b) The solubility of oxygen in water exposed to air at 0.89 atm = mole / L
c) Oxygen released from 4.70 L of water in an unsealed container If=
Concentration mole
The binding energy is calculated from the product of the mass defect and the square of the speed of light. First, we need to calculate for the mass defect. We do as follows:
m = mass products - mass of reactantsm = 33*1.00867 + 27*1.00728 - 59.9338 m = 0.54887
E = mc^2 = 0.54887 (3x10^8)^2 = 4.94x10^16 J
