Part B Write the balanced chemical equation for the neutralization reaction that occurs when an aqueous solution of hydrobromic

acid (HBr) is mixed with an aqueous solution of lithium hydroxide (LiOH). Indicate the physical states of the reactants and products using the abbreviations (s), (l), (g), or (aq) for solids, liquids, gases, or aqueous solutions, respectively. Express your answer as a chemical equation.

Answer:

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

Explanation:

A neutralization reaction is a process in which an acid, aqeous HBr reacts completely with an appropriate amount of base, aqueous LiOH to produce salt, aqueous LiBr and water, liquid H2O only.

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

Acid + base → Salt + Water.

During this reaction, the hydrogen ion, H+, from the HBr is neutralized by the hydroxide ion, OH-, from the LiOH to form the water molecule, H2O.

Thus, it is called a neutralization reaction.

On a .75-meter table sits a book whose mass is .5 kilograms. How
Pie

Answer:

P.E = 3.675  J

Explanation:

Given data:

Height of table = 0.75 m

Mass of book = 0.5 kg

Potential energy = ?

Solution:

Formula:

P.E = mgh

g =acceleration due to gravity =  9.8 m/s²

by putting values,

P.E = 0.5 kg× 9.8 m/s² ×0.75 m

P.E  = 3.675 kgm²/s²

J = kgm²/s²

P.E = 3.675  J

A scientist has two samples of gas: The first sample contains one mole of argon atoms and has a mass of 39.948 g; the second sam
V125BC [204]

There are 6.022 × 10²³ atoms in 39.948 g of argon and 4.0026 g of helium.

Explanation:

39.945 g/mole is the molar mass of argon so 39.948 g of argon are equal to 1 mole of argon.

4.0026 g/mole is the molar mass of helium so 4.0026 g of helium are equal to 1 mole of helium.

We know that Avogadro's number tell us the number of particles in 1 mole of substance which is 6.022 × 10²³.

So in 39.948 g of argon and 4.0026 g of helium contains the same number of atoms, 6.022 × 10²³.

Find the density of a gas at STP if it’s molar mass is 112g/mol
AleksandrR [38]

Answer:

D= 5 g/L

Explanation:

M= D x Vm

M is the molar mass = 112g/mol

D is the density

Vm is the molar volume whuch is 22.4L at STP

now substitute;

112 = D x 22.4

D= 112\22.4

D= 5 g/L
