When 15.6 g of fluorite (caf2) reacts with excess sulfuric acid, hydrogen fluoride gas is collected at 709 torr and 25.5Â°c. sol

lianna [129]

The reaction equation is:

CaF₂ + H₂SO₄ → 2HF + CaSO₄

The molar ratio between fluorite and hydrogen fluoride is 1 : 1.

The moles of fluorite supplied are:

Moles = 15.6 / 78.07
Moles = 0.200

The moles of hydrogen fluoride produced will be 0.2.

Now, we may use the ideal gas equation to determine the temperature:

PV = nRT
T = PV/nR

T = (899 * 7.4) / (0.2 * 62.36)

T = 533.40 K

The temperature will be 260.25 °C

Benzene is an organic chemical compound with the molecular formula C6H6. In the benzene molecule, carbon atoms form a ring with

Sergeu [11.5K]

Answer:

$sp^2$

Explanation:

Hello,

The six-carbon benzene ring contains two types of bonds: C-C and C-H bonds, that are $sp^2$ -hybridized σ bonds, and the six π bonds that form the aromatic ring. The σ bonds form from one $s$ orbital and two $p$ orbitals from each carbon, which then bond the carbon to the two carbons on either side and the carbon's single hydrogen. The remaining $p$ orbital from each carbon atom sticks out above and below the plane of the ring; these $p$ orbitals overlap sideways, rather than lengthwise, to form the aromatic π bond system.
