The correct answer for the question that is being presented above is this one: "CaCO3(s) <-> CaO(s) + CO2(g)." In this reaction will the point of equilibrium shift to the left when the pressure on the system is increased: <span>CaCO3(s) <-> CaO(s) + CO2(g)</span>
There are ten dL in one litre, so an ideal amount of lead in a litre of blood would be no greater than 400 micrograms (ug)
There's 1000mL in a litre, so we're looking at 0.4ug of lead or less in a millilitre. 1mol of lead atoms weighs about 207.2g, therefore there's about 2.907 × 10^21 atoms per gram, or about 1.163×10^14 atoms in 0.04ug. Therefore there should be no more than 1.2×10^14 atoms of lead per millilitre.
<span>Communication is the sharing of ideas and findings through writing and speaking, because you can process your experiment and collect data all you want, but until you share it with others and compare it with others, than is essentially useless. Open dialogue, open communications is where our ideas and findings really take form and become something worth while and productive to others.</span>
Answer:
No
Explanation:
There is a chart made just for density. It finds whatever liquid you want based on the density. 2 liquids cannot have the same density.
