in which type of compound are ionic bonds most commonly seen? in which type of compound are ionic bonds most commonly seen? organic inorganic
An ionic compound's two distinct ions separate from one another when it is dissolved in water.
Organic chemicals are typically not ionic. The vast majority of organic compounds have covalent connections. Covalent molecules are not made with ions. They are one molecule when there are no net charges (although may have charge separation).
Compounds of carbon and hydrogen that may or may not also contain other elements are referred to as organic substances. There are also some ionized organic compounds. Cyclopropenyl chloride, as an example. Ionic compounds conduct electricity due to the presence of ions in their aqueous state. The majority of organic materials, however, do not dissolve in water. But other compounds do dissolve easily, such as ethyl alcohol. As one can see, the terms "ionic" and "organic" are not equivalent or even mutually exclusive. In terms of organic and inorganic, respectively, ionic and covalent are equivalent notions. Both organic and inorganic compounds can be in ionic or covalent states. There would only be a broad distinction between organic and ionic if covalent and inorganic were assumed for organic and ionic for inorganic, respectively. Therefore, the decision would be between ionic and covalent molecules.

how is electronegativity used in determining the ionic and doric relevant character of the bonding between two elements
How polar a link will be depends on how differently electronegative two atoms are from one another. Since there is no variation in electronegativity in a diatomic molecule with two identical atoms, the bond is nonpolar or pure covalent.
What is polar and non polar?
Polarity is the term used to describe objects that differ at either end. Some molecules also contain positive and negative ends, and when this occurs, we refer to those molecules as being polar. We refer to someone as non-polar if they don't. Polar objects can be drawn to or repelled by one another (opposite charges attract, alike charges repel).

why did the big bang not produce a significant proportion of elements heavier than helium?
The big bang did not produce a significant proportion of elements heavier than helium because the temperatures and densities present in the early universe were not sufficient to support the fusion of heavier elements.
During the first few minute of the big bang, the universe was composed of mostly hydrogen and helium, with very small amounts of lithium and beryllium. As the universe expanded and cooled, the denser regions of the universe collapsed to form the first stars. Inside these stars, the intense pressure and heat generated by nuclear fusion reactions allowed for the production of heavier elements, such as carbon and oxygen. However, elements heavier than helium, such as iron and nickel, require even higher temperatures and densities to be produced, which can only be found in the cores of supernovae. Therefore, the big bang alone did not produce a significant proportion of elements heavier than helium.

consider the following reaction at equilibrium. what effect will increasing the volume of the reaction mixture have on the system? 2 h2s(g) 3 o2(g) 2 h2o(g) 2 so2(g) a) the reaction will shift to the right in the direction of products. b) no effect will be observed. c) the reaction will shift to the left in the direction of reactants. d) the equilibrium constant will decrease. e) the equilibrium constant will increase.
Option (a) is correct. If a reaction is at equilibrium and we will increase the volume of the reaction then the Reaction will shift to the right in the direction of product.
The Reaction is,
2H2S(g) + 3O2(g) ----> 2H2O(g) + 2SO2(g) a)
According to Le Chatelier's principle, if a dynamic equilibrium is disturbed by changing the conditions the position of equilibrium shifts to counteract the change to reestablish an equilibrium. If a chemical reaction is at equilibrium and experiences a change in pressure, temperature or concentration of products or reactants, the equilibrium shifts in the opposite direction to offset the change. A change in one of the variables that describe a system at equilibrium produces a shift in the position of the equilibrium that counteracts the effect of this change.
We are increasing pressure here. Reaction will try to decrease the pressure. Hence it will move in a direction which have lesser gaseous molecules. Here product has less gaseous molecule. So equilibrium will move to right. Equilibrium moves to product side.

The identity of the gas, given that 3.33 g occupies a volume of 1.365 L at 95 °C and 790 torr is chlorine gas (Cl₂)
How do I determine the identity of the gas?First, we shall determine the number of mole of the gas. This is obtained as follow:
Volume (V) = 1.365 L Temperature (T) = 95 °C = 95 + 273 = 368 KPressure (P) = 790 torr = 790 / 760 = 1.039 atmGas constant (R) = 0.0821 atm.L/Kmol Number of mole (n) =?PV = nRT
1.039 × 1.365 = n × 0.0821 × 368
Divide both sides by (0.0821 × 368)
n = (1.039 × 1.365) / (0.0821 × 368)
n = 0.0469 mole
Finally, we shall determine the identity of the gas as follow:
Mole of gas = 0.0469 mole Mass of gas = 3.33 gMolar mass of gas =?Molar mass = mass / mole
Molar mass = 3.33 / 0.0469
Molar mass of gas = 71 g/mol
From the above calculation, we can see that the molar mass of the gas is 71 g/mol.

Pressure has little effect on the solubility of liquids and solids because they are almost incompressible True.
Liquids and solids show little change in solubility with changes in pressure. As expected, gases increase in solubility with increasing pressure. Henry's Law states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.
External pressure has little effect on liquid and solid solubility. In contrast, the solubility of a gas increases as the partial pressure of the gas above the solution increases.
Solubility is a measure of the concentration of dissolved gas particles in a liquid and is a function of gas pressure. Increasing the gas pressure increases the number of collisions and increases the solubility, and decreasing the pressure decreases the solubility.

Explanation:
Sparking can be caused by defective cooktop elements, loose connectors, a wire with frayed insulation or a broken wire arcing over to the appliance metal frame, says Appliance Repair. If the cause of the sparking is a broken wire or a wire with frayed insulation, do not attempt to splice the wire; you must replace it. Repair Clinic suggests checking the spark ignition switches, as they might be defective and in need of replacing.

Which equation violates the Law of Conservation of Matter?
O A. 2 H₂SO3 + 4 H₂Se --> Sе6 + 6 H₂O
B. Al2(SO4)3 + 3 Ca(MnO4)2 → 2 Al(MnO4)3 + 3 CaSO4
5 HI 2 HIO3 --> 3 12 + 3 H₂O
Answer:
The equation that violates the Law of Conservation of Matter is 5 HI + 2 HIO3 --> 3 12 + 3 H₂O
Explanation:
This equation shows the formation of three molecules of iodine (I2) from two molecules of hydrogen iodate (HIO3) and five molecules of hydrogen iodide (HI), but it does not account for the atoms of iodine that are used to form the three molecules of iodine. According to the Law of Conservation of Matter, the total number of atoms of each element must be the same on both sides of a chemical equation, but in this equation, there are more atoms of iodine on the left-hand side than on the right-hand side. This means that the equation is not balanced, and it violates the Law of Conservation of Matter. The other equations listed are balanced and do not violate this law.
