Answer:

2 HNO3 + CaCO3 = Ca(NO3)2 + H2O + CO2

Explanation:

Given Equation :

HNO_3 + CaCO_3 = Ca(NO_3)_2 + H_2O + CO_2

Balanced Equation

2 HNO_3 + CaCO_3 = Ca(NO_3)_2 + H_2O + CO_2

What is the volume, in Liters, of 0.765 mol of carbon monoxide gas at STP?
aivan3 [116]

Answer:

The volume at STP of 0,765 moles of carbon monoxide gas is 17, 125 L.

Explanation:

We use the ideal gas formula, with the constant R = 0.082 l atm / K mol. The STP conditions are : 1 atm pressure and 273 K temperature. Solve for the formula, V (volume):

PV=nRT ---> V= (nRT)/P

V= (0,765 mol x0,082 l atm/ K mol x 273 K)/ 1 atm

<em>V= 17, 12529 L</em>

List the following molecules in order of increasing boiling point: Br2, Cl2, F2, I2.
Andrej [43]

Answer:

1. None of these have hydrogen bonding.

2. None of these have dipoles.

3. Bigger molecules will have stronger London dispersion forces. So I2 has the strongest forces,

and F2 will have the weakest. Correspondingly, I2 will have the highest boiling point and F2 will have the lowest boiling point.

Answer: F2, Cl2, Br2, I2
