To my Ex:

You hate me, but I still love you. I know your with someone else, but I'm still happy for you. Live on, and mabye we'll see each other in some restraunt in France, and you'll have your family, and I'll have mine, and we'll smile at each other but go our separate ways.

(Yes, I used a Batman quote.)

What volume would 3.00 moles of neon gas have at 295 K and 645 mmHg?
LUCKY_DIMON [66]

Answer:

V = 85.619 L

Explanation:

To solve, we can use the ideal gas law equation, PV = nRT.

P = pressure (645 mmHg)

V = volume (?)

n = amount of substance (3.00 mol)

R = ideal gas constant (62.4 L mmHg/mole K)

T = temperature (295K)

Now we would plug in the appropriate numbers into the equation using the information given and solve for V.

(645)(V) = (3.00)(62.4)(295)

(V) = (3.00)(62.4)(295)/645

V = 85.619 L

Complete and balance the molecular equation for the reaction of aqueous sodium carbonate, Na 2 CO 3 , and aqueous nickel(II) chl
pantera1 [17]

Answer:

NiCl2 (aq) + Na2CO3 (aq) ---> NiCO3 (s) + 2NaCl (aq)

Explanation:

Soluble ionic compounds exist as ions in solution.

Na 2CO3, will contain Na2CO3 (aq) --> 2Na ^+ (aq) + CO2 ^-3 (aq)

The same way, a solution of calcium chloride,  

CaCl 2, will contain CaCl2 (aq) --> Ca2^+ (aq) + 2Cl^−  (aq)

Mixing both solution, the calcium cations  

Ca 2^+ , will apir up with the carbonate anions,  CO2^−3 , and form the Insoluble calcium carbonate, CaCO ^3, which precipitates out of solution.

The complete ionic equation, which features all the ions that are present in solution, will be like this

2 Na^+ (aq) + CO2^−3 (aq) + Ca2^+ (aq) + 2Cl^−  (aq) --> CaCO 3 ↓ (s)  + 2Na^+ (aq) + 2Cl^− (aq)

Notice that you have two sodium cations and two chloride anions on the products' side, which is why you have  2NaCl

NiCl2 (aq) + Na2CO3 (aq) ---> NiCO3 (s) + 2NaCl (aq)
