Answer:

37.5 L

Explanation:

Initial Volume, V1 = 15L

Initial Pressure P1 = 4.5 atm

Final Pressure, P2 = 1.8 atm

Final Volume V2 = ?

The relationship between these variables is given as;

P1V1 = P2V2

V2 = PIV1 / P1

Inserting the values;

V2 = 4.5 * 15 / 1.8

V2 = 37.5 L

Answer: The new volume is 37.5L

Explanation:

The question is solved using the principle and formula of a gas law known as the Boyle's law. Boyle's law states that provided the temperature remains constant, the volume of a given mass of gas is inversely proportional to its pressure. Expressing the statement mathematically:

P ∝ 1/V, (where p is equal to pressure and V is volume)

Therefore PV = a constant

If a gas at pressure P1 and Volume V1 changes at constant temperature to pressure P2 and volume V2 then:

P1V1 = P2V2.

Using the formula to solve the question:

P1 = 4.5atm

P2 = 1.8atm

V1= 15L

V2 = ?

V2 = P1V1/P2

V2= 4.5 × 15 /1.8

V2 = 67.5/1.8

V2 = 37.5 L

Therefore the new volume is 37.5L

Explanation:

Explanation:

The balanced equation of the reaction is given as;

Mg(OH)2 (s) + 2 HBr (aq) → MgBr2 (aq) + 2 H2O (l)

1. How many grams of MgBr2 will be produced from 18.3 grams of HBr?

From the reaction;

2 mol of HBr produces 1 mol of  MgBr2

Converting to masses using;

Mass = Number of moles * Molar mass

Molar mass of HBr = 80.91 g/mol

Molar mass of MgBr2 = 184.113 g/mol

This means;

(2 * 80.91 = 161.82g) of HBr produces (1 * 184.113 = 184.113g) MgBr2

18.3g would produce x

161.82 = 184.113

18.3 = x

x = (184.113 * 18.3 ) / 161.82 = 20.8 g

2. How many moles of H2O will be produced from 18.3 grams of HBr?

Converting the mass to mol;

Number of moles = Mass / Molar mass = 18.3 / 80.91 = 0.226 mol

From the reaction;

2 mol of HBr produces 2 mol of H2O

0.226 mol would produce x

2 =2

0.226 = x

x = 0.226 * 2 / 2 = 0.226 mol

3. How many grams of Mg(OH)2 are needed to completely react with 18.3 grams of HBr?

From the reaction;

2 mol of HBr reacts with 1 mol of Mg(OH)2

18.3g of HBr =  0.226 mol

2 = 1

0.226 = x

x = 0.226 * 1 /2

x = 0.113 mol

According to the concept of Avogadro's number, there are 0.527×10²³molecules in  3.5 g of NaOH​.

Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.

It has a SI unit of reciprocal mole whose numeric value is expressed in reciprocal mole which is a dimensionless number and is called as Avogadro's constant.It relates the volume of a substance with it's average volume occupied by one of it's particles .

According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.

Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number.Number of molecules= 3.5/40×6.023×10²³=0.527×10²³molecules .

Explanation:

Avogadro's number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number.

Examples of herbivores are buffalo, elk, some bird species, mice, squirrels, rabbits, and many more.

To solve this, we must know each and every concept behind herbivores and  carnivores. Therefore, herbivores include cows, goats, giraffes, sheep, and zebras etc.

Herbivores, often known as herbivorous animals, are creatures that eat plants, leaves, fruits, and other plant-based foods for nourishment. They are classified as primary eaters and are found at levels 2 or above in the food supply chain.

Herbivores include cows, goats, giraffes, sheep, and zebras. Interestingly, there really are herbivores who specialize in eating on specific parts of the plant; for example, frugivores are herbivores that graze on fruits, whereas folivores are herbivore that eat on leaves.

Therefore, herbivores include cows, goats, giraffes, sheep, and zebras etc.

Explanation:

I think it's right. :)

When the pH increases suddenly in the flask at that point is a base no longer added during a titration.

Titration is a typical quantitative chemical analysis procedure used in laboratories to quantify the concentration of a specified analyte. The titrant or titrator is a reagent that is produced as a standard solution with a known concentration as well as volume.

The pH scale, which originally stood for "potential of hydrogen," is used to describe the acidity as well as basicity of aqueous solutions. The pH of acidic solutions is lower than that of basic as well as alkaline solutions.
