If the bond energy between atoms is very high the the bond between the atoms is strong.

<h3>What are chemical bonds?</h3>

Chemical bonds are formed wen two atoms are combined together. The chemical bonds are responsible for holding the atoms together. These chemical bonds could be ionic or covalent in nature. Coordinate bonds have hybrid behavior between ionic and covalent bond types.

We know that the bond energy refers to the energy that must be supplied in order to break the bonds. A high bond energy implies that it takes a whole lot of energy to break the bond. If it takes a lot of energy to break the bond, then the bond must be a strong bond which holds the two atoms together in the compound. Hence, if the bond energy between atoms is very high the the bond between the atoms is strong.

Answer:

2. precipitate is formed

Explanation:

In this reaction barium nitrate and sodium sulfate solutions react to form a barium sulfate precipitate.Barium and sulfate ions will react to give barium sulfate precipitate where as the sodium and nitrate ions are spectator ions.

The net ionic equation after removing unchanged ions from each side of the full ionic equation will be;

Atoms of iron (fe) and sulfur (s) form iron sulfide (fes) when the iron atom donates electrons to the sulfur atom. the type of b

marysya [2.9K]

Answer:

The type of bond formed in FeS would be <u>Polar Covalent Bond</u>.

Explanation:

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

Less than 0.4 then it is Non Polar Covalent Bond

Between 0.4 and 1.7 then it is Polar Covalent Bond

Greater than 1.7 then it is Ionic Bond

For Fe and S,

E.N of Sulfur = 2.58

E.N of Iron = 1.83

________

E.N Difference 0.75 (Polar Covalent Bond)

A silver block, initially at 57.2 ∘C, is submerged into 100.0 g of water at 24.8 ∘C, in an insulated container. The final temper

Masteriza [31]

Answer:

96.5 grams is the mass of the silver block.

Explanation:

Heat lost by iron will be equal to heat gained by the water

$-Q_1=Q_2$

Mass of iron = $m_1=?$

Specific heat capacity of silver= $c_1=0.240 J/g^oC$

Initial temperature of the silver= $T_1=120^oC$

Final temperature = $T_2=T=26.5^oC$

$Q_1=m_1c_1\times (T-T_1)$

Mass of water= $m_2=100.0 g$

Specific heat capacity of water= $c_2=4.184 J/g^oC$

Initial temperature of the water = $T_3=24.8 ^oC$

Final temperature of water = $T_2=T=26.5^oC$

$Q_2=m_2c_2\times (T-T_3)$

$-Q_1=Q_2$

$-(m_1c_1\times (T-T_1))=m_2c_2\times (T-T_3)$

On substituting all values:

$-(m_1\times 0.240 J/g^oC\times (26.5^oC-57.2^oC))=100.0 g\times 4.184 J/g^oC\times (26.5^oC-24.8^oC)$

we get, $m_1 = 96.5 g$

96.5 grams is the mass of the silver block.

molecular orbital theory correctly predicts paramagnetism according to mo theory, overlap of two p atomic orbitals produces .oxy

Mkey [24]

Overlap of two p atomic orbital produces oxygen gas ,o2 because it has two unpaired electron and explains paramagnetism.

O2 molecules have two unpaired electrons Materials in which all the electrons are paired are diamagnetic. It repel a magnetic field.Para magnetic and diamagnetic materials do not act as permanent magnets. Molecular orbital theory provides an explanation of chemical bond that explains paramagnetism of the oxygen molecule. It also explains the bonding in a other molecule. O2 molecule has two unpaired electron. Electrons creates magnetic field as it goes to the ground state and also spin.MO theory describes the distribution of electrons in molecules same as the distribution of electrons in atoms described using atomic orbital.
