Calcium Chloride reacts with sodium carbonate (aq) to form solid calcium carbonate and aqueous sodium chloride. Determine the volume of a 2.00M Calcium chloride solution that would be needed to exactly react with 0.0750L of 1.00M sodium carbonate. (Use BCA table)

1. Nitrogen and hydrogen combine at the same rate that ammonia breaks down.

2. Both calcium carbonate and sodium carbonate are being produced.
3. The reaction is reversible.
4. 300,000 km/s
5. The people are moving much slower than the speed of light so the ground acts as a frame of reference.

True or False?

Will Donald Trump be President in January 20, 2025?

False.

Why false?

As an AI language model, I cannot predict future events, and it is not known whether Donald Trump will be the President on January 20, 2025.

What is the true answer then?

I cannot provide a true answer because it is not predictable through factual information or data. The future outcome of such an event cannot be determined with certainty and is subject to changing circumstances and factors that may arise.

I have no idea what a BCA table is. BCA might be "beginning", "change", A?

mols mols Na2CO3 = M x L = 0.075
...CaCl2 + Na2CO3 ==> CaCO3 + 2NaCl
Convert mols Na2CO3 to mols CaCl2 by
0.075 mols Na2CO3 x (1 mol CaCl2/1 mol CaCl2) = 0.075 x 1/1 - 0.075. So now you know 0.075 mols Na2CO3 will require 0.075 mols CaCl2.
Then M = mols/L. You know mols CaCl2 and M CaCl2; solve for L
