Answer:

Sr(NO3)2 + Na2CO3 --------> SrCO3 + 2NaNO3

Total ionic equation;

Sr^2+ + NO3^- + Na^+ + CO3^2- -----> SrCO3 + 2NaNO3

Net ionic equation;

Sr^2+ + CO3^2- -----> SrCO3

Explanation:

The molecular equation shows the reactions of the compounds to give the products. It shows the molecular formula of reactants and products.

The total ionic equation shows the ions that recombine to form the products of the reaction.

The net ionic shows the major ionic reaction that took place in the system.

Hence, the net ionic equation explicitly shows the major species that are involved in a reaction, while a complete ionic equation includes the spectator ions.

Four moles of Argon gas are at a pressure of 1.90 atm, and the temperature is 50 degrees C. What is the volume of the gas?
soldier1979 [14.2K]
N = 4 moles of Ar2, P = 1.90 atm, V = ?
T = 50C = 273 + 50K = 323K
PV = nRT --> V = nRT/P
V = (4)(.0821)(323)/1.90
V = 106.07/ 1.9
V = 55.8 L

Match each term with its definition.
padilas [110]

Answer:

The position of an equilibrium always shifts in such a direction as to relieve a stress applied to the system -Le Chåtelier's principle

A molecule that donates a proton when it encounters a proton acceptor.- Bronsted-Lowry acid

Occurs when a reaction involving an acid and its conjugate base is combined with a second reaction involving a base and its conjugate acid.- Neutralization

It ionizes completely when dissolved in water.- Strong acid

The shift in the position of equilibrium caused by the addition of a participating ion.- Common ion effect

It only partially ionizes when dissolved in water.- Weak electrolyte

It is capable of acting as either an acid or a base depending upon the solute- Amphoteric solvent

The act of self-ionization of a solvent to produce both a conjugate acid and a conjugate base.- Auto-protolysis

A chemical species that bears both positive and negative charges.- Zwitterion

Explanation:

In the answer box we have various chemical terminologies and their definitions. In answering the question, you must carefully read through each definition, then check what option best matches that definition from the options provided.

Each definition applies only to one terminology as you can see in the answer above.
