In the reaction above, how many moles of sodium chloride would be produced
if you started with 20 grams of magnesium chloride and excess sodium
phosphate? The equation is not balanced.
(If anyone can answer in depth if appreciate it )

Answers

Answer 1

Answer:

24.5 g of NaCl

Explanation:

We begin from the balanced reaction:

3MgCl₂ +   2Na₃PO₄  →    6NaCl   +  Mg₃(PO₄)₂

If the sodium phosphate is in excess, then the limting reagent is the magnessium chloride.

We convert mass to moles:

20 g . 1mol / 95.2g = 0.210 moles.

3 moles of MgCl₂ can produce 6 moles of NaCl

0.210 moles of salt, may produce (0.210 . 6) /3 = 0.420 moles

Ratio of reactant is twice the product

We convert the moles to mass:

0.420 mol .  58.45 g/mol = 24.5 g

Silver has two isotopes, one with 60 neutrons and the other with 62 neutrons. The natural abundance of these are 51.83% and 48.17% respectively. Give the chemical notation for each of these isotopes and calculate the average atomic mass for silver.

Answers

The average atomic mass of silver is approximately 108.3324. The mass of an atom is defined as its atomic mass.

How to calculate atomic mass ?

The two isotopes of silver are Ag-107 (60 neutrons) and Ag-109 (62 neutrons).

To calculate the average atomic mass of silver, we need to multiply the mass of each isotope by its natural abundance, then add these values together.

Ag-107 has a mass of 107

Natural abundance of 51.83%,

so its contribution to the average atomic mass of silver is 107 * 0.5183 = 55.8391

Ag-109 has a mass of 109 and a natural abundance of 48.17%,

so its contribution to the average atomic mass of silver is 109 * 0.4817 = 52.4933

The average atomic mass of silver is the sum of these two values,

which is 55.8391 + 52.4933 = 108.3324.

So, the average atomic mass of silver is approximately 108.3324.

Answers

The freezing point of a solution containing 10.0 g of glucose C6H12O6 in 100 g of H2O is -0.53°C.

What is freezing point?

Freezing point is the temperature at which a liquid turns into a solid. It is the temperature at which a liquid's vapor pressure is equal to the atmospheric pressure. The freezing point of pure water is 0°C (32°F), while most other liquids have different freezing points. Some liquids, such as ethanol, have a lower freezing point than water, while others, such as propylene glycol, have a higher freezing point.

Why does freezing point decrease when pressure increases?

Answers

When the pressure of a liquid is increased, so is the number of molecules that can fit into a given space.

What is freezing point?

Freezing point is the temperature at which a liquid turns into a solid. The freezing point of a substance is the temperature at which its molecules stop moving and form into a solid crystal. Generally, the freezing point of a liquid is lower than its boiling point. For example, water freezes at 32°F (0°C) and boils at 212°F (100°C).

This compression of molecules increases the interactions between them and weakens the intermolecular bonds that hold them together. This weakening of the bonds reduces the amount of energy needed to separate the molecules, causing the freezing point to decrease. In other words, when the pressure of a liquid increases, the molecules are more tightly packed and the freezing point decreases.

Acidic substances are typically easy to recognise by their sour flavours. A molecule that can donate an H+ ion and keep its energetic favorability even after losing H+ is a basic definition of an acid. Blue litmus paper is known to turn red when exposed to acids.

Bases, on the other hand, have a smooth consistency and a bitter flavour. A base that may dissolve in water is known as alkali. When these substances interact chemically with acids, salts are created. Red litmus has a history of becoming blue on bases.

What will be the freezing point of an aqueous solution containing 80.0 g of NaCl?

Answers

The freezing point of an aqueous solution containing 80.0 g of NaCl will be -21.2 °C.

What is aqueous solution?

An aqueous solution is a solution that consists of a solvent and solute, where the solvent is water. Water is able to dissolve many different types of molecules and ions, making it an ideal solvent for many applications. Aqueous solutions are ubiquitous in nature and form the basis of many biological processes. In chemistry, aqueous solutions are used as a medium to conduct chemical reactions, as they allow for the solubilization of reactants and products.

This is because NaCl is an electrolyte and increases the freezing point of a solution by lowering the vapor pressure. When NaCl dissolves in water, it separates into individual ions and the ions interact with the water molecules, making it harder for the water molecules to escape into the vapor phase, which in turn increases the boiling point and decreases the freezing point. The freezing point depression of an aqueous solution containing 80.0 g of NaCl can be calculated using the formula ΔTf = Kf·m, where Kf is the molar freezing point constant for water and m is the molality of the solution. The molality of the solution can be calculated by dividing the mass of the solute (NaCl) by its molar mass and then dividing that by the mass of the solvent (water). So, the molality of the solution is 0.522 mol/kg and the freezing point depression is -21.2°C.

Solubility is the ability of a substance to dissolve in a liquid. It is a measure of how much of a substance can be dissolved in a given amount of a liquid. Solubility is affected by temperature, pressure, and the presence of other substances. Different substances have different solubilities; for example, sugar is more soluble in water than salt.

This means that at this temperature, 36.0 g of NaCl will dissolve in every 100 mL of water, or 36.0 g of NaCl will dissolve in every liter of water. The solubility of NaCl is temperature dependent, meaning that the solubility will change as the temperature changes.

What is concentration?

Concentration is the ability to focus one's attention on a task or activity, blocking out distractions and remaining focused on the task at hand. It is a skill that helps us to stay focused and avoid being easily sidetracked. Concentration is often thought of as being a key factor in academic success, as well as having an important role in the workplace. It can also be beneficial in everyday life, helping us to stay organized and on top of our commitments and responsibilities.

Concentration is a skill that can be developed and improved with practice. Strategies such as setting specific goals, breaking down complex tasks into smaller steps, and taking regular breaks can help to improve concentration. Additionally, reducing distractions such as background noise, social media, and other forms of entertainment can help to create an environment that is more conducive to concentration. Finally, making sure to get enough rest and exercise can also help to improve concentration.
It is calculated by dividing the mass of the solute (15 grams) by the volume of the solution (5 liters). To put it another way, the concentration of the solution is 3 grams of solute for every liter of water. This type of concentration is commonly expressed as either g/L or mg/L (milligrams per liter).
