Nesterboy [21]

Answer:

ΔHreaction = 263.15 kJ/mol

Explanation:

The reaction is as follow:

OH + CF₂Cl₂ → HOF + CFCl₂

You need to calculate the enthalpy of reaction and for this it is necessary to know the standard enthalpies for each of the compounds. These enthalpies are as follows and can be found in your textbook or on the Internet.

ΔHreaction = ∑ΔHproducts - ∑ΔHreactants

delta(H)_{reaction} =((1*(-97.8)+(1*(-92))-((1*39)+(1*(-491.15))=263.15kJ/mol

Which nonmetal would an ion of Ca2+ MOST LIKELY ionically bond with in a 1:1 ratio? A) one atom of neon B) one atom of carbon C)
GalinKa [24]
Ca2+ would bond to any element in a 1 to 1 ratio that had an equal and opposite charge.

Neon is a noble gas, and doesn’t form bonds m

Carbon isn’t typically found in ion state, but if it did, it would likely by C4+

Flouring in ionic state is F1-, so you would need 2 flourines to cancel the 2+ charge of Calcium

Then the only option left would be Oxygen which, when in ion form is found be 2-

Is a solution a homogeneous or heterogeneous mixture
Alja [10]

Answer:

Solutions are always homogeneous.

Explanation:

Solution:

Solution are considered homogeneous because in solution the ratio of solute and solvent remain the same throughout the solution. Both solute and solvent are chemically combined and form a new substance.

In solution the particles of solute can not be seen through naked eye.

When the light is passed through the solution it can not scattered.

Example:

When salt is dissolve in water it makes a solution.

The solution also exist in gaseous form. For example oxygen and many other gases dissolved in nitrogen also form a solution.

Mixture:

In mixture substance are physically combined. In mixture every every individual particle retain their properties.

It can be consist of solid, liquid and gas.

Examples:

Sand in water is also a mixture.

Oil in water form mixture.
