how many grams of ethylene glycol, c2h4(oh)2, must be added to 600 g of water to yield a solution that will freeze at -7.55 oc?
For a solution to freeze at -7.55°C, 600g of water and 62.07 g/mol of generated ethylene glycol must be combined.
(ΔT)=k×m×i
Where k equals -12.9°C kg/mol, the freezing point constant
mol solute/kg solvent, where m is the molality
Your Van't Hoff factor is I and since ethylene glycol is a molecule that doesn't dissociate in water, I equals 1.
Technically, we also know ΔT, which is -7.55°C, as the typical freezing point of water is 0°C.
We will rearrange to solve for the molality since that is the only value we DO NOT have.
T/(k×i)=m
-12.9 °C/(-7.55 °C)kg/mol=m
mol/kg = 0.59 m
0.6 kilogram of water with 600.0 g (or 0.98 mol) of ethylene glycol
Since ethylene glycol has a molar mass of 62.07 g/mol, you would require 61.04 grams, or 0.98 g, to make a solution with a freezing point of -7.55 °C.

suppose you mix 100.0 g of water at 23.2 oc with 75.0 g of water at 71.9 oc. what will be the final temperature of the mixed water, in oc?
The final temperature of the mixed water is 17.43°C.
Principle of Calorimeter:
The body at a higher temperature releases heat while the body at a lower temperature absorbs heat. The principle of calorimetry indicates the law of conservation energy, i.e. the total heat lost by the hot body is equal to the total heat gained by the cold body.
From the calorimeter principle we have:
heat loss by hot water = Heat gained by the cold water
The formula for the heat gained or loss:
Q = m.c.ΔT
Q = heat gained or loss
c = specific heat
ΔT = temperature change
m1 = 100g
m2 = 75g
m2c ΔФ2 = m1c ΔФ1
75 × (71.6-T) = 100× ( T - 23.2)
5370 - 75T = 100T - 2320
175 T = 3050
T = 17.43°C
Therefore the final temperature is 17.43°C

who developed the idea of the atomic nature of matter
The idea of the atomic nature of matter was first developed by John Dalton.
He introduced the atomic theory, which proposed that matter was made up of tiny, indivisible particles called atoms. This theory was based on his observations and experiments on the behavior of gases
.Dalton's atomic theory had several postulates that helped explain the properties of matter. These postulates were:
All matter is made up of atoms, which are tiny, indivisible particles
.Each element is composed of atoms that are identical in size, shape, and chemical properties.
Atoms of different elements have different sizes, shapes, and chemical properties.
Atoms combine in fixed ratios to form compounds, and the ratios of their masses are related by whole numbers.
Atoms are indestructible and cannot be created or destroyed in chemical reactions
.However, Dalton's atomic theory was later modified and expanded upon by other scientists, including J.J. Thomson, Ernest Rutherford, and Niels Bohr, as new discoveries about the structure and behavior of atoms were made.

Which property of matter is conserved in chemical reactions and shown by balanced equations?
The property of matter that is conserved in chemical reactions and shown by balanced equations is known as the Law of Conservation of Mass. According to this law, mass can neither be created nor destroyed in a chemical reaction; it can only be transformed from one form to another.For instance, when two substances are combined, they react and form a new substance.
The products that are formed contain the same number of atoms as the reactants, but in different configurations. To keep track of the number of atoms on either side of the equation, we use coefficients, which indicate the number of molecules or atoms of each substance in the reaction. However, when a chemical equation is written, it must adhere to the law of conservation of mass.The law of conservation of mass is critical in chemical reactions because it ensures that the amount of reactants that go into a reaction equals the amount of products that come out of it. This means that the total mass of reactants must equal the total mass of the products. As a result, the balanced chemical equation must reflect this law.For example, consider the reaction between hydrogen gas and oxygen gas, which forms water. The balanced chemical equation is as follows:2H2 + O2 → 2H2OIn this reaction, two molecules of hydrogen gas react with one molecule of oxygen gas to produce two molecules of water. The coefficients in the balanced chemical equation indicate that two molecules of hydrogen and one molecule of oxygen combine to form two molecules of water, obeying the law of conservation of mass.In conclusion, the Law of Conservation of Mass is a fundamental principle in chemistry that is used to balance chemical equations. It is critical in chemical reactions because it ensures that the total mass of reactants equals the total mass of products, allowing scientists to accurately predict the outcome of a chemical reaction.For such more question on chemical reaction

A) increases the negative charge of an atom or compound
B) decreases the positive charge of an atom or compound
C) is independent of reduction
D) occurs when the electrons are lost from an atom or compound
Oxidation D) occurs when the electrons are lost from an atom or compound. Oxidation refers to a chemical reaction where there is a transfer of electrons from one substance to another.
During oxidation, the substance that loses electrons is known as the reducing agent while the substance that gains electrons is known as the oxidizing agent. When an atom or compound loses electrons during oxidation, it becomes more positively charged, and this results in a decrease in its negative charge.
For example, when iron rusts, it undergoes oxidation as it loses electrons to oxygen. The iron atoms lose their electrons, and as a result, they become positively charged. This causes the iron compound to have a more positive charge than it did before the oxidation process.
In summary, oxidation occurs when electrons are lost from an atom or compound, which results in a decrease in the negative charge of the compound or atom.

How many hydrogen are lost when a pi bond is formed?
When a pi bond is formed, one hydrogen is lost from each of the atoms involved in the bond formation. This is because a pi bond is formed when two parallel p orbitals overlap sideways, and each p orbital contains one electron.
Therefore, in order for the electrons to form a bond, one electron from each atom must be involved, leading to the loss of one hydrogen atom from each atom.
When a pi bond is formed, two hydrogen atoms are lost. This occurs because the pi bond involves the sharing of two additional electrons between two atoms, typically carbon, which results in the need to release two hydrogen atoms to maintain proper valence.
Valence is a term used in chemistry and physics to describe the number of electrons that an atom can gain, lose, or share in order to form a chemical bond with another atom. The valence of an atom is determined by the number of electrons in its outermost shell, or valence shell.
The valence of an atom is important because it determines its ability to form chemical bonds with other atoms. Atoms with a low valence (i.e. only a few electrons in their outermost shell) tend to lose those electrons and become positively charged ions, while atoms with a high valence (i.e. many electrons in their outermost shell) tend to gain electrons and become negatively charged ions.

Which action happens at the microscopic scale as the temperature of a substance decreases and it eventually freezes?
The speed of the particles rises with the temperature of the solid, liquid, or gas. The particles slow down with decreasing temperature.
A liquid can turn into a solid if it is cooled down far enough.
Why does a liquid become a solid when its temperature drops?The average kinetic energy of the molecules falls as a liquid cools.
The liquid eventually turns into a solid when the quantity of heat removed is sufficient to cause the molecules to be attracted to one another.
Freezing is the process of transitioning from a liquid to a solid.
It loses thermal energy when the liquid cools. Its constituent particles therefore decelerate down and converge.
