How would you distinguish between calcium hydrogen carbonate and sodium hydrogen carbonate without using any lab chemical
No chemical. Use a flame test. NaHCO3 will give the bright yellow color of sodium while Ca(HCO3)2 will give the orange-red color of Ca. Works every time.
Well, wondering if water is considered a lab chemical here. Heat each separately to decompose, then stir each of the decomposed results into water. One decomposition will dissolve, one will not. Figure out the decomposition's..

Boil 5 ml of both calcium hydrogen carbonate
To distinguish between calcium hydrogen carbonate (Ca(HCO3)2) and sodium hydrogen carbonate (NaHCO3) without using any lab chemicals, you can focus on a few key characteristics.
1. Solubility: Calcium hydrogen carbonate is only slightly soluble in water, while sodium hydrogen carbonate is highly soluble. You can conduct a simple solubility test by adding a small amount of each compound separately to water and observing the extent of their dissolution. Calcium hydrogen carbonate will appear as a cloudy suspension in water, whereas sodium hydrogen carbonate will dissolve completely, resulting in a clear solution.
2. Reaction with acids: Both compounds react with acids, releasing carbon dioxide gas. However, the rate of the reaction can differ. Calcium hydrogen carbonate reacts more slowly compared to sodium hydrogen carbonate. You can perform an acid test by adding a few drops of vinegar or lemon juice to separate samples of each compound. The calcium hydrogen carbonate sample will produce carbon dioxide gas more slowly, resulting in a gradual effervescence, while the sodium hydrogen carbonate sample will produce a quicker and more vigorous release of gas.
It's important to note that these tests can provide a good indication but are not foolproof. For a definitive identification, laboratory tests with appropriate chemicals and equipment are required.
