From the given pH, we calculate the concentration of H+:
[H+] = 10^-pH = 10^-5.5
We then use the volume to solve for the number of moles of H+:
moles H+ = 10^-5.5M * 4.3x10^9 L = 13598 moles
From the balanced equation of the neutralization of hydrogen ion by limestone written as
CaCO3(s) + 2H+(aq) → Ca2+(aq) + H2CO3(aq)
we use the mole ratio of limestone CaCO3 and H+ from their coefficients, which is 1 mole of CaCO3 is to react with 2 moles of H+, to compute for the mass of the limestone:
mass CaCO3 = 13598mol H+(1mol CaCO3/2mol H+)
(100.0869g CaCO3/1mol CaCO3)(1kg/1000g)
= 680 kg
The density does not change because it is still the same liquid as before
Elements with complete electron shells are most likely noble gases which have 8 valence electrons in their outer shell. So the letter farthest to the right should be the correct answer. Noble gases are found in group 18
The scientist should form a hypothesis and design an experiment.
This way they can properly follow the scientific process.
That statement is false
If the gaseous water molecules were greater than the liquid molecules ( which commonly happened if the temperature of the water is increased) , the water will evaporate
