Describe and identify the type of reaction that occurs between potassium carbonate and nitric acid

2. A. Based on your results, why do you think that HCI was a stronger electrolyte then acetic acid? (Hint - How does the fact that acetic acid is a weak acid, which only partially dissociates in water, while HCl is a strong acid which completely

A population in an ecosystem cannot grow indefinitely. There are limiting factors in each ecosystem that keep a population within a certain size range.

The phase change that is reverse of evaporation is

Calculate the molar mass of the following using the periodic table: 1.) HCl 2.) ZnF2 3.) K2CO3 4.) FePO4 5.) Cu2S

O identify a liquid substance, a student determined its density. using a graduated cylinder, she measured out a 45-ml sample of the substance. she then measured the mass of the sample, finding that it weighed 38.5 g.
