During the combustion of 5.000 g of octane, C8H18, 239.5 kcal is released. Write a balanced equation for the combustion reaction
lidiya [134]

The chemical equation for this combustion reaction is:

<span>C8H18  +  O2  -->  CO2  +  H2O</span>

 

Balancing by adding whole number coefficients:

<span>2 C8H18  + 25 O2  -->  16 CO2  + 18 H2O</span>

 

Including the phases:

<span>2 C8H18 (l)  + 25 O2 (g)  -->  16 CO2 (g) + 18 H2O (l)</span>

<span>where g is gas and l is liquid</span>

Which are the chemical properties of water?
Pachacha [2.7K]

Answer:

See explanation.

Explanation:

Hello,

In this case, we can realize that water has a very simple atomic structure which consists of two hydrogen atoms bonded to one oxygen atom. The nature of the atomic structure of water causes its molecules to have unique electrochemical properties. The hydrogen side of the water molecule has a slight positive charge whereas at the other side of the molecule a negative charge exists. This molecular polarity causes water to be a powerful solvent and is responsible for its strong surface tension.

Moreover, water is involved in several both inorganic and organic chemical reactions leading to hydration, for example, the conversion of alkenes to alcohols, the hydrolysis of acyl halides, anhydrides, esters and amides to carboxylic acids and the hydration of a raft of inorganic salts that exist as hydrates only, such as copper (II) sulfate pentahydrate and so.

Best regards.

7. What volume of a 0.10 mol/l HCl solution is needed to neutralize 10 ml of a 0.15
svp [43]

Answer: The volume of a 0.10 mol/l HCl solution needed to neutralize 10 ml of a 0.15 mol/l LiOH solution is 15 ml

Explanation:

To calculate the volume 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 HCl

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

We are given:

n_1=1\\M_1=0.10mol/L\\V_1=?mL\\n_2=1\\M_2=0.15mol/L\\V_2=10mL

Putting values in above equation, we get:

1\times 0.10\times V_1=1\times 0.15\times 10\\\\V_1=15mL

Thus the volume of a 0.10 mol/l HCl solution needed to neutralize 10 ml of a 0.15 mol/l LiOH solution is 15 ml
