Question- For questions such as whether if something is soluble in water, base or acid, whats the most convienient way to approach this with mostly inspection?
Example - is lead carbonate soluble in water, base or acid?
I am not able to get the correct answer please help me

Gaseous ammonia (NH3, 2.00 L, 703.8 torr, 23.8C) reacts with aqueous sulfuric acid (H2SO4, 0.500M, 175mL) to produce solid ammonium sulfate. 4.8275 g of product is isolated.
two excited triplet states are found 13814 and 15891 cm^-1 above the ground state. calculate the Helmholtz energy for this molecule at room tempreature and 1 atm.
If 141 mL of wet H2 is collected over water at 24°C and a ba?rometric pressure of 738 torr, how many grams of Zn have been consumed.
According to the valence bond theory, which of the following molecules involves sp2 hybridization of orbitals on the central atom?
Assume that the buret represenst H+ ions, the flask represents OH- ions, and you are carrying out a titration of the base with the acid.
Aluminum and oxygen react according to the following equation: 4 Al (s) + 3 O2 (g) → 2 Al2O3 (s) What mass of Al2O3, in grams, can be made by reacting 4.6 g Al with excess oxygen
A certain amount of glucose, C6H12O6 burned in oxygen, and produced 22 grams of carbon dioxide, CO2. How many grams of water was produced at the same time?
a) Explain the octet rule. b) Briefly describe two situations which are exceptions to the octet rule; include relevant chemical formulas to support your descriptions.
Based on your answer to (1), would you be more or less confident about your density measurement if you used the smaller sample volume, rather than the normal 8 mL sample volume? Briefly explain.
An alloy containing Al is analyzed. All the solution reacts with 212mL of 0.493M HCl in the 2.500g sample of alloy. calculate the mass percent of Al in the alloy.
HCL solution has a lower concentration than what is indicated. will this result indicate the presence of more or less moles of base in the antacid
