Answer:
The energy content of substances is related to the physical state in which the substance exists. Molecules of gases are always in motion as they possess very high kinetic energy, hence, they exist as gases. Liquid molecules are less energetic than gas molecules, hence they have less flow than gases. Solid molecules on the other are fixed at a place because they possess very low kinetic energy and can only vibrate about their fixed positions.
Explanation:
The three states in which matter exist are solid, liquid and gas.
Solids are made of molecules that are closely packed together and held together by strong intermolecular forces. The particles in a solid possess very low kinetic energy and are not free to move about but can only vibrate and rotate about their fixed positions.
Liquids particles are able to move about as they possess enough kinetic energy to limit or reduce the strength of the intermolecular forces binding them together. Thus, liquids can flow.
The particles in a gas are relatively far apart and possess kinetic energy more than the particles of a liquid or solid. The intermolecular forces binding particles of gas together are weak due to the very high kinetic energy of yhe gas particlest
Answer:
The claim is untrue.
Explanation:
Given the information from the question. We need to evaluate the claim.
According to the phase rule we have F= C-P+2
In this particular situation, the forms are completely allotropic .In order words, they are conjured through the same chemical composition. Thus constituents C= 1, P=4 for four phases and the number variables is 2. As a result, F= C-P+2 =1-4+2= -1. Therefore, the claim is untrue.
Aldehyde is a group of organic compounds with the general form of RCHO. Oxidation of aldehyde can lead to the formation of the carboxylic acids, with the general form of RCO₂H.
With this oxidation, the typical reagents promoting the oxidation are chromic acids, chromate salts, permanganate, etc.
Answer:
(a) 0.575 m;
(b) 0.527 m
Explanation:
Let's use the freezing point depression law in each of these cases.
(a) According to the law:
Rearrange the equation for molality, b:
NaCl is an ionic substance, 1 mole of it dissociates into 2 moles of ions, sodium ion and chloride ion, this means the van 't Hoff factor i = 2.
Here:
is the initial freezing point of water,
is the final freezing point of water.
For water:
Applying the equation
(b) Applying the same equation for the same salt and the same conditions, except a new freezing point, we would expect to obtain:
Elemental sulfur occurs as octatomic molecules, 63.2 g F2 are needed to react completely with 17.8 g S8 to produce SF6 .
<h3>What is octatomic molecules?</h3>
When stable under normal temperature and pressure circumstances, an octatomic element is a chemical element that has eight atoms arranged in a group. Sulfur, symbol S8, is the classic example, but red selenium is also an octatomic element that is stable at ambient temperature.
A molecule with eight sulfur atoms has a puckered ring or crown structure. Sulfur is in an octet state when it contains two more electrons than the six in its outermost shell. Sulfur has an atomic number of 16 and an electrical configuration of 2, 8, 6.
Other elements (S, Se, and Te) exist as octatomic solids while oxygen is a diatomic gas at normal temperature.
