CaCO3 + 2HCl > CaCl2 + CO₂ + H₂O​

Explanation:

This reaction is also known as double decomposition reaction.

HCl + CaCO3 + MgCO3 → H2O + H2 + CO2 + CaCl2 + MgCl2

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
