Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
Explanation:
It will produce high concentration of hydrogen ions if acid ionises completely in water.
Answer is: <span>50 g of nitrogen has a volume of 40 liters at stp.
m(N</span>₂) = 50 g.
n(N₂) = m(N₂) ÷ M(N₂).
n(N₂) = 50 g ÷ 28 g/mol.
n(N₂) = 1,785 mol.
V(N₂) = n(N₂) · Vm.
V(N₂) = 1,785 mol · 22,4 L/mol.
V = 40 L.
Vm - molare volume on STP.
I think it would be B maybe
