How many grams of lithium hypochlorite are there in 1.35 mol?

Chemistry
1 answer:
kow [346]2 years ago
3 0

Hey there!:

Molar mass  lithium hypochlorite (  LiClO ) = 58.4 g/mol

Therefore:

1 mole LiClO --------------------- 58.4 g

1.35 moles LiClO --------------  ( mass LiClO ) ??

So:

1.35 * 58.4 / 1  => 78.84 g of LiClO


Hope that helps!

Answer:

In science, sound is defined as the transfer of energy from a vibrating object in waves that travel through matter. Most people commonly use the term sound to mean what they hear when sound waves enter their ears. The tree above generated sound waves when it fell to the ground, so it made sound according to the scientific definition

Nitrogen monoxide, NO, reacts with hydrogen, H₂, according to the following equation.
Anvisha [2.4K]

Answer : The rate law for the overall reaction is, Rate=k[NO]^2[H_2]

Explanation :

Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

As we are given the mechanism for the reaction :

Step 1 : 2NO+H_2\rightarrow N_2+H_2O_2    (slow)

Step 2 : H_2O_2+H_2\rightarrow 2H_2O     (fast)

Overall reaction : 2NO+2H_2\rightarrow N_2+2H_2O

The rate law expression for overall reaction should be in terms of NO\text{ and }H_2.

As we know that the slow step is the rate determining step. So,

The slow step reaction is,

2NO+H_2\rightarrow N_2+H_2O_2

The expression of rate law for this reaction will be,

Rate=k[NO]^2[H_2]

Hence, the rate law for the overall reaction is, Rate=k[NO]^2[H_2]

Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous butane into gaseous carbon d
Phantasy [73]

Answer:1.

1.Balanced equation

C4H10 + 9 02 ==> 5H20 +4CO2

2. Volume of CO2 =596L

Explanation:

1.Combustion of alkane is the reaction of alkanes with Oxygen. And the general equation for the combustion is;

CxHy +( x+y/4) O2 ==> y/2 02 + xCO2

Where x and y are number of carbon and hydrogen atoms respectively.

For butane (C4H10)

x=4 and y=10

Therefore

C4H10 + 9 02 ==> 5H20 +4CO2

2. Mass of butane = 0.360kg

Molar mass of C4H10 = ( 12×4 + 1×10)

= 48 +10=58g/mol= 0.058kg/mol

Mole = mass/molar mass

Mole = 0.360/0.058= 6.2moles

From the stoichiometric equation

1mole of C4H10 will gives 4moles of CO2

Therefore

6.2moles of C4H10 will gives 4 moles of 24.8 moles of CO2

Using the ideal gas equation

PV=nRT

P= 1.0atm

V=?

n= 24.8mol.

R=0.08206atmL/molK

T=20+273=293

V= 24.8 × 0.08206 × 293

V= 596L

Therefore the volume of CO2 produced is 596L

Question 1 (True/False Worth 2 points) (04.03 LC) When Pb and AlCl3 react together, lead (Pb) can replace aluminum (Al) in the c
aivan3 [116]

Answer:

For 1: The correct answer is false.

For 2: The correct answer is Na_3PO_4+3KOH\rightarrow 3NaOH + K_3PO_4, because K retains the same charge throughout the reaction.

For 3: The correct answer is Zn+H_2SO_4\rightarrow ZnSO_4 + H_2

For 4: The correct answer is a single replacement reaction takes place because sodium is more reactive than hydrogen.

For 5: The correct answer is False.

For 6: The correct answer is it is a single replacement reaction, and the cations in the two ionic compounds are different.

Explanation:

  • <u>For 1: </u>

This type or reaction is based on the reactivity series. If the metal which lies above in the series will replace the metal which lies below in the series easily.

From the reactivity table attached below, we know that lead lies below in the series to Aluminium and hence, it will not replace in the reaction.

Pb+AlCl_3\rightarrow \text{No reaction}

Hence, the correct answer is False.

  • <u>For 2: </u>

A balanced equation is defined as the equation in which there are same number of atoms present on the reactant side and the product side.

The balanced equation always follow Law of Conservation of Mass.

So, from the given options, the below equation is the balanced equation because K retains the same charge throughout the reaction.

Na_3PO_4+3KOH\rightarrow 3NaOH + K_3PO_4

  • <u>For 3:</u>

A single displacement reaction is a type of chemical reaction in which one element replaces another element in a chemical reaction. The element which is more reactive will replace the less less reactive element.

This is explained by reactivity series as the metal which lies above in the series will replace the metal which lies below in the series easily. From the given equations, the equation which is a type of single displacement reaction is:

Zn+H_2SO_4\rightarrow ZnSO_4 + H_2

Ba(OH)_2+H_2SO_4\rightarrow BaSO_4 + 2H_2O : This equation is a type of double displacement reaction.

2Mg+O_2\rightarrow 2MgO  : This equation is a type of combination reaction.

H_2O+CO_2\rightarrow H_2CO_3 : This equation is a type of combination reaction.

  • <u>For 4:</u>

A single displacement reaction is a type of chemical reaction in which one element replaces another element in a chemical reaction.

A+BC\rightarrow AC+B

A double displacement reaction is a type of chemical reaction in which exchange of ins takes place.

AB+CD\rightarrow AD+BC

In the question, it is asked that sodium metal is reacting with water to produce hydrogen gas and sodium hydroxide. This reaction is a type of single displacement reaction because sodium is more reactive than hydrogen as shown in the reactivity series.

2Na+2H_2O\rightarrow H_2+2NaOH

  • <u>For 5: </u>

A single displacement reaction is a type of chemical reaction in which one element replaces another element in a chemical reaction. This reaction will not follow when an element replaces similar element.

Hence, the statement is False.

  • <u>For 6:</u>

For the reaction:

\text{Metal + Ionic compound}\rightarrow \text{Metal + Ionic compound}

It is a type single replacement reaction as the cations in the two ionic compounds are different.

For Example:

3Na+AlCl_3\rightarrow 3NaCl+Al

Where, Sodium and Aluminium are the cations and chlorine is an anion.
