When 15.0 g of fluorite (CaF₂) reacts with excess sulfuric acid, hydrogen fluoride gas is collected at 744 torr and 25.5°C. Soli
8090 [49]

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 / 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 = (875 * 8.63) / (0.2 * 62.36)

T = 605.45K

The temperature will be 331.85 °C  which is  required to store the gas in an 8.63-L container at 875 torr.

how many monochloro substitution products are produced when the alkanes below are chlorinated? consider constitutional isomers o
Airida [17]

When the alkanes below are chlorinated they produce 3 monochloro substitution products. These isomers have the same chemical formula, but their atoms arrangements are different.

What are constitutional versus isomeric isomers?

Although structural (constitutional) isomers share the same chemical formula but their atoms are bonded in a different way. Stereoisomers have the same atomic configurations and chemical formulae. The groups' spatial orientation is the only thing which distinguishes the molecules distinguishes them from one another.

What are instances of stereoisomers?

According to the general definition of stereoisomers, stereoisomers are isomers with the same composition (i.e., the same parts), but different orientations in space. Stereoisomers are of two different types which are enantiomers and diastereomers.

Learn more about stereoisomers from the link given below.

How do you calculate the number of neutrons???? please help
vladimir1956 [14]

Answer:

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Atoms of which types of elements tend to gain electrons? Atoms of which types of elements tend to lose electrons?
ollegr [7]
Atoms of elements that are nonmetals tend to gain electrons and atoms of metallic elements tend to lose electrons. Metals have few electrons in their valence shells. By losing those electrons, these metals achieve noble gas configuration and satisfy the octet rule. Nonmetals that have close to 8 electrons in their valence shells readily accept electrons to achieve noble gas configuration. An example is the reaction between calcium and oxygen. Calcium is a metal and has 2 valence electrons. Oxygen is a nonmetal and has 6 valence electrons. Calcium gives up its two valence electrons and oxygen accepts them and an ionic bond is established resulting in the formation of anew compound namely calcium oxide.
