This is because intermolecular forces have a greater effect in a solution when bonding is present than in a vacuum when bonding is not present.

The attracting and repellent forces that develop between the molecules of a substance are known as intermolecular forces or IMF for short. Individual molecules of a substance interact with one another through the mediation of these forces.

Most of the physical and chemical features of matter are caused by intermolecular forces.

An intermolecular force is an attractive force that develops between the protons or positive parts of one molecule and the electrons or negative parts of another molecule. This force affects a substance's many physical and chemical properties. The strength of a material's intermolecular forces directly relates to the boiling point of that substance; the stronger the intermolecular forces, the higher the boiling point.

Answer:

T° = 453.6 K

Explanation:

Let's apply the Ideal Gases Law to solve the question:

Pressure . Volume = number of moles . R . T°

We replace data:

5.5 atm . 35.3L = 5.2 mol . 0.082 L.atm/mol.K .T°

T° = (5.5 atm . 35.3L) / (5.2 mol . 0.082 L.atm/mol.K)

T° = 453.6 K

The Ideal Gases Law contains the Absolute value of T° (Kelvin degrees)

So the final answer is: 453.6 K

You can also determine this, because the unit of R (Ideal Gases constant)

Based on the information, UV light is more likely to damage the material.

Due to the fact that the infrared light bounces off the quartz, which increases its energy, the quartz may become warm.

The colors of paper and fabric can deteriorate due to ultraviolet light from the sun. In the presence of ultraviolet light waves, the chemicals in colored dyes can degrade. Sunburns may also result from ultraviolet radiation.

-Iodine was placed after tellurium because it has a lower atomic mass

Answer: Moving?

Explanation:

108gm of hydrogen gas is present in2600ml container at 35-degree Celsius and at pressure of 165mm Hg.

Given data:

water = 2600ml

temp = 35°C & 95k

pressure = 165mm Hg & 0.162atm

From given information we apply ideal das equation to get moles.

PV = nRT

0.162atm * 2600ml = n 0.0821 * 95k

n = 54

Now we know 1 mole of hydrogen contain 2.016gm hydrogen.

In 54 moles we have 108gm hydrogen.

Diatomic elements are elements that exist as molecules composed of two atoms of the same element.

Diatomic molecules are molecules composed of two atoms, such as Oxygen (O2), Hydrogen (H2), Nitrogen (N2), and Fluorine (F2). Diatomic molecules are the most common type of molecules in nature and are found in all three states of matter (solid, liquid, and gas). Diatomic molecules contain only two atoms and do not contain any other elements or molecules.

This is in contrast to other elemental substances, which exist as individual atoms or molecules composed of different elements. Diatomic elements have unique chemical and physical properties due to the strong bond between the two atoms.

The zeroth law of thermodynamics describes the state where we can say what about the movement of heat between two substances

The Zeroth Law of thermodynamics is a basic law that describes the state in which two bodies are in thermal equilibrium. It states that if two bodies are in thermal equilibrium with a third body, then they are in thermal equilibrium with each other. In other words, it allows us to determine if two bodies are at the same temperature and if there is no heat flow between them. So, it describes the state where there is no movement of heat between two substances.

According to the concept of Avogadro's number and STP conditions volume in liters of the sample is 15,388.7.

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.

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 moles is obtained as, number of atoms/Avogadro's number=4.088×10²⁴/6.023×10²³=6.78 moles on substitution in formula of PV=nRT=V=6.78×8.314×273/1=15,388.7 liters.

Following is the list of primary secondary and tertiary alcohols.

Alcohols are chemical compounds made composed of an alkyl or aryl group and a hydroxyl group (ROH). A fundamental alcohol is a hydroxyl carbon with just one R group. If it contains two R groups, it is a secondary alcohol, and if it has three R groups, it is a tertiary alcohol.

Look at the carbon bonded to OH to identify whether an alcohol is primary, secondary, or tertiary. The alcohol is primary, secondary, or tertiary depending on how many other carbons are connected to that carbon. It is methanol if there are three hydrogens and no carbons, which is a rare combination.

Pyruvate is converted to lactate in anaerobic conditions by anaerobic glycolysis. During anaerobic respiration, two ATP molecules are produced.

What is the primary step in glycolysis?

The method by which glucose is metabolized to produce energy is known as glycolysis. It generates water, ATP, NADH, and two pyruvate molecules. It doesn't need oxygen to happen because it happens in a cell's cytoplasm. Both in aerobic and anaerobic organisms, it happens.

How is glycolysis referred to?

Gustav Embden, Otto Meyerhof, & Jakub Karol Parnas identified the Embden-Meyerhof-Parnas (EMP) pathway, which is the most typical kind of glycolysis.

Answer:

1 gram of H2 will be produced from 12 grams of Mg.

Explanation:

According to Stoichiometry, 0.5 moles of Mg are present. 1 mole of Mg produces 1 mole of H2, so 0.5 moles of Mg will produce 0.5 moles of H2. Multiplying molar mass of H2 i.e. 2 gram/mole with 0.5 moles, we can find the mass of H2 in grams which is 1 gram.

The order of [NO] is 2.

The rate law for a chemical reaction is an equation that describes how the rate of the reaction changes with respect to the concentrations of the reactants. In this case, the rate law for the reaction 2NO(g) + O2(g) → 2NO2(g) is Rate = k[O2][NO]^2.

The order of a reactant in a rate law is determined by the exponent to which its concentration is raised. In this case, the concentration of NO is raised to the power of 2, so the order of [NO] is 2. This means that the rate of the reaction is directly proportional to the square of the concentration of NO. Therefore, as the concentration of NO increases, the rate of the reaction will increase at a faster rate.

Being a highly chemically reactive metal having seven valence electrons and even a high attraction for electrons, bromine reacts quickly as well as violently with alkali metals, therefore is rarely found in nature pure.

Despite being a potent oxidizer, it is difficult to break down under typical circumstances. Fluorine was the strongest active halogen, followed by chlorine, bromine, as well as iodine.

Since bromine has a higher atomic radius over chlorine, it is much less reactive. Compared to chlorine, bromine does not hold electrons as tightly. This is supported by the fact that chlorine contains fewer electron shells, which causes the electrons to connect nearer to the nucleus.

Due to its lower reactivity, the bromine radical is so much more selective for such 2° radical. Cl• is much less picky and less selective since it is less stable as well as more reactive.
