The polarity can be established using the electronegativity (obtained from the periodic table). The best and simplest approach to tell if a molecule is polar or non-polar, though, is to look at its molecule shape.
A molecule is considered to be polar if its core atom has a single pair of electrons. For instance, H2O is polar because the oxygen atom's lone pairs give it a non-symmetrical shape (bent or v-shaped molecular geometry). So, no lone pairs are non-polar, right? Wrong. Not all molecule having a single lone atom at their centre are non-polar. They might be linear or tetrahedral, for sure, but that depends on what is connected to the main atom. For instance, CCl2F2 is polar while CH4 is a non-polar chlorofluorocarbon.

What is pH ?
pH, a quantitative measure of the acidity or basicity of aqueous or other liquid solutions. Widely used in chemistry, biology, and agriculture, this term translates the concentration value of hydrogen ions (usually in the range of about 1 to 10-14 gram-equivalents per liter) into a number between 0 and 14. increase. At neutral (neither acidic nor alkaline), the concentration of hydrogen ions is 10−7 gram equivalents per liter, which corresponds to a pH of 7. Solutions below pH 7 are considered acidic.

A student is studying barium, a highly reactive element that is used in some paints. Which characteristic of barium is most closely related to its chemical reactivity?.
High ionization energy is the property of barium that is most directly connected to its chemical reactivity.
Has barium a high level of reactivity?There are two valence (outermost) electrons in each of their atoms. Because it is in period 5 or row 5, barium has valence electrons in its fifth shell, although they can be lost very quickly.
This explains why oxygen and other electronegative substances, like barium, make it so reactive. In a nutshell, when atom size increases, the ionization energy drops.
Barium is larger and has higher energy levels than strontium because it is in a different period—the sixth—than strontium, which is in a different period. As a result, barium will have a lower ionization energy.

Stereoisomers and constitutional isomers typically have the same connectivity but different spatial configurations. Although structural isomers share the same molecular formula, their atoms are bound differently. The atomic configurations and chemical formulae of the stereoisomers are identical.
What distinguishes structural and conformational isomers from one another?Two major groups of isomers are constitutional isomers and stereoisomers (molecules of the same chemical formula). Stereoisomers and constitutional isomers typically have the same connectivity but different spatial configurations.
Although structural isomers share the same molecular formula, their atoms are bound differently. The atomic configurations and chemical formulae of the stereoisomers are identical. Only the groups' spatial orientation within the molecule distinguishes them from one another.
Stereoisomers known as isomeric isomers are those that cannot be changed into one another by rotating a molecule around a single bond. Geometric isomers and optical isomers are the two different categories of these configurational isomers.
Cis-trans isomers are another name for geometric isomers. Alkanes tend to exhibit this form of isomerism more frequently than other alkanes.
When two identical groups (connected to the vinyl carbon atoms) are present, geometric isomerism refers to whether they are on the same side of the double bond or the other. It is referred to as the cis-isomer if the two identical groups are on the same side and as the trans-isomer if they are on opposite sides.

which combination of ionic charge and ionic radius give the largest lattice enthalpy for an ionic compound?
Combination of ionic charge and ionic radius give the largest lattice enthalpy for an ionic compound are:
Ionic charge = high, Ionic Radius = small
Understanding Ionic bondsUnderstanding Ionic bonds Ionic bonds occur due to the handover of electrons to form positive ions and negative ions whose electron configuration is the same as that of the noble gases. Positive ions and negative ions are bound by an electrostatic force. The resulting compounds are called ionic compounds. One example that we often encounter everyday is table salt.
Well, the chemical formula for table salt is NaCl (Sodium chloride). In solid NaCl there is a bond between Na⁺ ions and Cl⁻ ions by electrostatic forces, so it is called an ionic bond. The crystal form of NaCl is a series of Na⁺ ions and Cl⁻ ions. One Na⁺ ion is surrounded by six Cl⁻ ions and one Cl⁻ ion is surrounded by six Na⁺ ions .
Formation of Ionic bondEach element must try to have an electron configuration like that of a noble gas, either by releasing electrons or accepting electrons, so that it is stable. This electron handover event occurs in the NaCl compound/ table salt.
Na belongs to group IA where IA has 1 valence electron, so that to be stable IA must release 1 electron. If you look at the electron configuration, 11Na: 2, 8, 1. So when removing 1 electron, the last electron becomes 8 (according to the octet rule). Due to removing 1 electron, the originally neutral Na becomes charged +1 (Na⁺).
The reaction:
Na → Na⁺ + e⁻ (meaning Na loses 1 electron, see the electron is to the left of the arrow)

The 4s orbital in the electronic configuration of a germanium should be filled first before 3d orbital because 4s orbital has a less energy than 3d orbital.
The electronic configuration of element is written in the order which is given in the attached image. The order of filling electron is given by Madelung rule in which electrons tries to achieve the order which fills the energy sublevels of atoms. According to the Aufbau principle, electrons occupy the lowest energy sublevel.
In other words, the orbital with a smaller value of n+l will be filled first. The n and l value for 4s orbital is 4 and 0 respectively. The n and l value for 3d orbital is 3 and 2. Hence, their n+l value will be
4s=(4+0)=4
3d=(3+2)=5
Hence, the electronic configuration of germanium should be written as 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰.

In suspension the solute does not dissolve in liquid and when placed on table for sometime and it will settle down at the bottom of the beaker and we can separate particles of solute easily from solvent through filtration and the colloid particles of solute does not dissolve in liquid neither it is settle down and it float through the solvent and in solution the particles of solute dissolve in to the solvent and we cannot identify them as separate we cannot separate them by filtration and in compound the two element combine to form a new thing and resultant compound have two new or different properties other than its ingredients so the correct answer is suspension

the combustion of liquid octane, c8h18, in the presence of gaseous oxygen yields carbon dioxide and liquid water.what are the reactants in the reaction described
Any hydrocarbon may be completely burned to produce carbon dioxide and water.
What byproducts are produced during octane combustion?Octane, or C8H18, is a component of the fuel that powers your automobile. Octane burns to produce CO2 and water when it is burnt. The availability of oxygen is the primary component in the process. In an oxygen-free environment, combustion is impossible.
2 water molecules to 2 carbon dioxide molecules make up the molar ratio. For every mole of water in the molecule H2O, there are two moles of hydrogen atoms.
Carbon monoxide (CO) and water are byproducts of the incomplete combustion of octane, C8H18.
Carbon dioxide and water are the byproducts of a complete combustion process of any fuel.
