Which compound is most likely to contain ionic bonds? which compound is most likely to contain ionic bonds? mgf2 ch4 n2o?

1 answer:

6 0

Answer is: MgF₂, magnesium fluoride.
Magnesium fluoride is salt, ionic compound, because magnesium is metal from 2. group of Periodic table of elements and has low ionisation energy and electronegativity, which means it easily lose valence electons, fluorine is nonmetal with greatest electronegativity, which meand it easily gain electron, so magnesium cation (Mg²⁺) and fluorine anion (F⁻) are formed.

The chemical equation for the formation of ammonia is unbalanced.

galben [10]

Answer:

The answer to your question is 2 molecules

Explanation:

Unbalanced chemical reaction

H₂(g) + N₂(g) ⇒ NH₃ (g)

Reactants Elements Products

2 H 3

2 N 1

Balanced chemical reaction

3H₂(g) + N₂(g) ⇒ 2NH₃ (g)

Reactants Elements Products

6 H 6

2 N 2

From the balanced chemical reaction we conclude that when 3 molecules of hydrogen react with one molecule of nitrogen, 2 molecules of ammonia will be formed.

What is the thermochemical equation for the combustion of methane. Methane formula: CH4 (g) and the deltaH comb -891 (kJ/mol)

-Dominant- [34]

The thermochemical reaction for combustion of methane is the balanced chemical equation for the combustion reaction with the enthalpy change and states of the reactants included.
Combustion is when an organic compound reacts with O₂ to yield CO₂ and H₂O.
thermochemical reaction for combustion of methane is as follows;
CH₄(g) + 2O₂(g) --> CO₂(g) + 2H₂O(g) ΔH = -891 kJ/mol

what kind of attractive forces must be overcome to melt ice boil molecular bromine melt solid iodine and dissociate f2 into f at

Shkiper50 [21]

Answer: to melt ice= hydrogen bond must be broken, boiling of molecular bromine and the melting of solid iodine= dispersion force must be broken, and

dissociation of f2 into f atoms= covalent bond must be overcome.

Explanation:

(1).For the melting of ice, the hydrogen bond in ice is directional and linear. The Hydrogen bond in ice is as strong as covalent bond. Ice melts to form water that is the breaking of Hydrogen bonds plus the breakage of dispersion interactions.

Hydrogen bond is an electrostatic interactions between hydrogen atom that is bonded to a more electronegative atom for example, oxygen, Halogens and so on.

(2). and (3).;

For the boiling of molecular bromine and the melting of solid iodine and dissociate f2 into f atoms; iodine molecule is a non polar molecule,hence only dispersion force will be overcome. Iodine sublime because they have covalent bonds within the bonds.

To dissociate F2 molecule, the forces of the covalent bond must be broken.

Suppose that 25 g of each substance is initially at 27.0 °c. what is the final temperature of each substance upon absorbing 2.35

riadik2000 [5.3K]

Answer:

a. gold : 755.7°C.

b. silver: 418.7°C.

Explanation:

a. gold :

It is known that:

The amount of heat absorbed by gold = Q = m.c.ΔT.

where, m is the mass of Au (m = 25.0 g).

c is the specific heat capacity of Au = 0.129 J/g°C.

ΔT is the temperature difference = (final T - 27.0°C).

Q = 2.35 kJ = 2350.0 J.

∴ The amount of heat absorbed by Au = Q = m.c.ΔT = 2350.0 J.

∴ 2350.0 J = (25.0 g)(0.129 J/g°C)(final T - 27.0°C).

∴ 2350.0 J = 3.225 final T - 87.08.

∴ 3.225 final T = 2350.0 + 87.08 = 2473.

∴ final T = 2473/3.225 = 755.7°C.

b. silver:

It is known that:

The amount of heat absorbed by silver = Q = m.c.ΔT.

where, m is the mass of Ag (m = 25.0 g).

c is the specific heat capacity of Ag = 0.24 J/g°C.

ΔT is the temperature difference = (final T - 27.0°C).

Q = 2.35 kJ = 2350.0 J.

∴ The amount of heat absorbed by Ag = Q = m.c.ΔT = 2350.0 J.

∴ 2350.0 J = (25.0 g)(0.24 J/g°C)(final T - 27.0°C).

∴ 2350.0 J = 6.0 final T - 162.0.

∴ 6.0 final T = 2350.0 + 162.0 = 2512.

∴ final T = 2512/6.0 = 418.7°C.
