Answer : The products of the acid-base reaction between $HClO_3$ and LiOH are, $LiClO_3$ and $H_2O$

Explanation :

Neutralization reaction : It is a type of chemical reaction in which an acid react with a base to give salt and water as a product that means it reacts to give a neutral solution. It is also known as acid-base reaction.

The acid-base reaction will be:

$HClO_3+LiOH\rightarrow LiClO_3+H_2O$

Therefore, the products of the acid-base reaction between $HClO_3$ and LiOH are, $LiClO_3$ and $H_2O$

A 25 liter gas cylinder contains 10 mole of carbon dioxide. Calculate the pressure, in atm, of the gas at 325K.

Arada [10]

<u>Answer:</u> The pressure of carbon dioxide gas is 11 atm

<u>Explanation:</u>

To calculate the pressure of gas, we use the equation given by ideal gas equation:

PV = nRT

where,

P = pressure of the gas = ?

V = Volume of gas = 25 L

n = number of moles of gas = 10 mole

R = Gas constant = $0.0821\text{ L atm }mol^{-1}K^{-1}$

T = temperature of the gas = 325 K

Putting values in above equation, we get:

$P\times 25L=10mol\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times 325K\\\\P=11atm$

Hence, the pressure of carbon dioxide gas is 11 atm

Solutions with low pH values have which of these properties?

telo118 [61]

Answer:

The correct option is C.

Solutions with low pH values have sour taste.

Explanation:

Low pH value show acidic property which can be define as , -log of conc. of hydrogen ion.

Acid has following properties

Sour taste
Turn blue litmus into red
corrosive

-OH group: Base have OH groups. So it is not correct option so it not correct for low pH i.e. acid

turns litmus paper blue: Base turn red litmus into blue, so it not correct for low pH i.e. acid

feels slippery: Bases are mostly slippery like soap

tastes sour: Sour taste is for acid and bitter taste is for base. So it is correct option for acid

Both compounds A and B have molecular formula C6H14. Monochlorination of compound A results in the formation of two constitution

Katarina [22]

Answer:

The name of the two compounds will be:

A :2,2-dimethylbutane

B: 3-methylpentane

Explanation:

The compounds are the isomers of hexane as per the given molecular formula.

There is no unsaturation or no ring is present in the compound.

Constitutional isomers are the one which have different arrangement of chain.

The possible compounds are shown in the figure with the products of monochlorination of the two isomers.

Thus there are five possible isomers of hexane.
