Which statement describes the bonds in iron sulfate, FeSO4?

Chemistry
1 answer:
Feliz [49]2 years ago

___

Regarding the bonds in FesO₄, Fe and S have an ionic bond, while S and O have covalent bonds.

Elements form bonds to increase their stability. The main types of bonds are:

  • Metallic bonds: they are formed between metals and the electrons are in a delocalized cloud.
  • Ionic bonds: they are formed between metals (lose electrons) and nonmetals (gain electrons)
  • Covalent bonds: they are formed between nonmetals, which share electrons.

Regarding the bonds in FesO₄:

  • Fe is a metal and S a nonmetal, thus they will form ionic bonds.
  • S and O are both nonmetals, thus they will form covalent bonds.

Regarding the bonds in FesO₄, Fe and S have an ionic bond, while S and O have covalent bonds.

Which of the following solvent pairs could be used in a solvent pair recrystallization (in general, not for this specific reacti
lilavasa [31]

Answer:

(a) Ethyl acetate and hexane, and (c) methanol and methylene chloride.

Explanation:

re-crystallization is a technique used to purify solid compound.   Ethyl acetate and hexane are good solvent pair for recrystallization because they are miscible with each other due to their good differences in polarity. ethyl acetate has polarity of 77 while hexane has 68.

water and diethyl ether are not good solvent pair for recrystallization because water and diethyl ether are immiscible. They have very far polarity values. water has 100 while diethyl ether has 35

Which type of property can be observed only by changing a substance into a different substance
Nana76 [90]

Chemical Property

<u>Explanation:</u>

When a substance is changed into another substance, may be due to addition of some other substance or removal of water from that substance.

* its identity changes

*its reactivity changes

*reactivity towards water, air and many other substances will change

*its chemical composition changes

and all these changes occurs due to the chemical properties.

If the physical property changes then there will be change in the state of matter, but its boiling point, melting point , reactivity towards water, air and other substances will not change, and it will not lose its identity.

A chemist dissolves 248mg of pure hydrochloric acid in enough water to make up 140mL of solution.Calculate the pH of the solutio
evablogger [386]

Answer : The pH of the solution is, 1.31

Explanation : Given,

Mass of HCl = 248 mg = 0.248 g      (1 mg = 0.001 g)

Volume of solution = 140 mL

Molar mass of HCl = 36.5 g/mole

First we have to calculate the concentration of hydrochloric acid.

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

\text{Molarity}=\frac{\text{Mass of }HCl\times 1000}{\text{Molar mass of }HCl\times \text{Volume of solution (in mL)}}

Now put all the given values in this formula, we get:

\text{Molarity}=\frac{0.248g\times 1000}{36.5g/mole\times 140mL}=0.0485mole/L=0.0485M

The concentration of HCl is, 0.0485 M

As we know that, HCl dissociates to give hydrogen ion and chloride ion.

The dissociation reaction is:

HCl\rightarrow H^++Cl^-

Concentration of HCl = Concentration of H⁺ = Concentration of Cl⁻ = 0.0485 M

Now we have to calculate the pH of the solution.

pH : It is defined as the negative logarithm of hydrogen ion concentration.

Mathematically,

pH=-\log [H^+]

pH=-\log (0.0485)

pH=1.31

Therefore, the pH of the solution is, 1.31
