Answer: Option (b) is the correct answer.

Explanation:

When a compound contains a strong bond between its combining atoms or molecules then the compound will have a high boiling point.

An ionic bond is a strong bond because it contains strong force of attraction between two oppositely charged atoms.  

For example, LiF is an ionic compound in which lithium is Li^{+} ion and fluorine is F^{-} ion.

Therefore, LiF compound will have strong force of attraction.

On the other hand, covalent compounds have weak bond due to sharing of electrons. Hence, they have low boiling point.

For example, CO_{2}, CCl_{4}, and H_{2} etc are covalent compounds.

Thus, we can conclude that LiF substance has the highest boiling point.

Answer: Lithium Fluoride

Explanation: Let’s see,,,
1. Obviously not hydrogen or carbon dioxide because they’re gas at room temp.
2. Lithium Fluoride is an ionic compound which means they have higher intermolecular forces and require more energy to break them, so it probably has a higher boiling point.

Determine which of the following statements is true:
alukav5142 [94]

Answer:

A. When an anhydrous salt becomes hydrated, it can change color.

Explanation:

The cobalt (II) chloride (CoCl₂) have a blue color in the anhydrous form while after hydration, most commonly it will form the hexahydrate, it will change its color to violet.

B. not really, if we take the cobalt (II) chloride in the anhydrous form the bond between cobalt and the chloride it is ionic.

C. nope, the mass is changed depending on the lost water mass

D. no, the mass will increase and sometimes as in the case of cobalt (II) chloride the color will change, so you have changes of the physical properties of the substance.

You have a 2.0 mL sample of acetic acid (molar mass 60.05 g/mol) of unknown concentration. You titrate it to its endpoint with 2
Katyanochek1 [597]

<u>Answer:</u> The mass of acetic acid used is 0.12 grams

<u>Explanation:</u>

To calculate the concentration of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is CH_3COOH

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is NaOH.

We are given:

n_1=1\\M_1=?M\\V_1=2.0mL\\n_2=1\\M_2=0.1M\\V_2=20.0mL

Putting values in above equation, we get:

1\times M_1\times 2.0=1\times 0.1\times 20.0\\\\M_1=\frac{1\times 0.1\times 20.0}{1\times 2.0}=1M

To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

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

Given mass of acetic acid = ? g

Molar mass of acetic acid = 60.05 g/mol

Molarity of solution = 1 M

Volume of the solution = 2.0 mL

Putting values in above equation, we get:

1mol/L=\frac{\text{Mass of acetic acid}\times 1000}{60.05g/mol\times 2.0}\\\\\text{Mass of acetic acid}=\frac{1\times 60.05\times 2}{1000}=0.12g

Hence, the mass of acetic acid used is 0.12 grams

Why can alkaline batteries not be recharged
LUCKY_DIMON [66]

Answer:

The biggest risk with recharging alkaline batteries is leakage. As you probably know, alkaline batteries leak even under normal circumstances. Internal off gassing, made worse by heat, creates pressure that can breach battery seals. Therefore, the risk of leakage is an even bigger risk when recharging.

Balance the following chemical equation:<br>__N2H4+<br>__O2 =<br>__NO2 +<br>__H2O​
Deffense [45]

The answer for the following question is mentioned below.

N_{2}H_{4} +3 O_{2} →2 NO_{2} +2 H_{2} O

the equation is balanced.

Explanation:

The steps required to balance a chemical equation is:

Firstly,write the formula of the compound/substance.

Secondly,count the number of atoms in each element on each side of the equation

Thirdly,Adjust the co-efficient.Balance the atoms or the ions present in the greatest number.

You may do this by finding the lowest common multiple of two.

Continue systematically to balance the atoms or ions on the rest of the side (i.e.)on the other side.

Lastly,check the number of atoms each elements is same on both the sides

From the equation:

Before balancing the equation:

N_{2} H_{4} + O_{2} → NO_{2} + H_{2} O

After balancing the equation:

N_{2}H_{4} +3 O_{2} →2 NO_{2} +2 H_{2} O

Therefore the given equation is balanced.
