Hello!

The molarity of the HBr solution is 0,172 M.

Why?

The neutralization reaction between LiOH and HBr is the following:

HBr(aq) + LiOH(aq) → LiBr(aq) + H₂O(l)

To solve this exercise, we are going to apply the common titration equation:

M1*V1=M2*V2

M1=\frac{M2*V2}{V1}= \frac{0,215 M * 37,5 mL}{47 mL}=0,172 M

Have a nice day!

An ordered list of chemical substances is shown.
alina1380 [7]

Answer : The correct option is, (C) 2, 4 and 5.

Explanation :

Combustion reaction : It is a type of reaction in which a hydrocarbon react with an oxygen molecule to give carbon dioxide, water as a product.

For example : Methane react with oxygen to give carbon dioxide and water.

CH_4+2O_2\rightarrow CO_2+2H_2O

In the given list of chemical substances, CuO,Cu_2O,Li_2O are in oxide form. They can not be both reactant and product of a single combustion reaction.

In the given list, C_2H_5NH_2 is the only hydrocarbon which shows a combustion reaction. That means C_2H_5NH_2 react with O_2 to give CO_2,H_2O and N_2 as a product.

The balanced combustion reaction of C_2H_5NH_2 is,

20C_2H_5NH_2+40O_2\rightarrow 40CO_2+7H_2O+10N_2

Therefore, the correct answer is, (C) 2, 4, and 5.

Why is all matter affected by gravity ​
Vlad [161]

Answer:

Explanation:

Gravity:

It is the force by which the elements of matter pulls together.

Explanation:

The gravity is depend upon the mass of matter. The more mass of object the more will be the gravitational force.

The earth is most heavier than all other matter that's why all matter pulls towards the earth.

For example;

when we walk on the earth, it pull us. Our mass is less as compared to the earth that's why we fall back on the earth instead of moving upward because our pull is negligible because of greater difference in masses. The earth mass is very high.

The gravitational force is inversely proportional to the square distance of interacting objects.

As the two objects are more distance apart from each other the less will be the gravitational force.
