The most stable oxidation state (oxidation number) for manganese is 2+, which has a pale pink color, and many manganese(II) compounds are COMMON, such as manganese(II) sulfate (MnSO4) and manganese(II) chloride (MnCl2). The 2+ oxidation state is the state used in living organisms for essential functions; other states are toxic for the human body. The 2+ oxidation of manganese RESULTS from removal of the TWO 4s electrons, leaving a HIGH spin ion in which all five of the 3d orbitals contain a SINGLE electron.Hey Mate!!!! Here is your answer ♣️

A PERCENT V/v SOLUTION is calculated by the following FORMULA USING the milliliter as the base measure of volume (v):% v/v = mL of solute/100 mL of solution.Example:X % = 5.0 mL HCl/100 mL of solution.X/100 = 5.0/100.100X = 500.X = 5.0% % v/v.

its small size, the carbon atom can FORM multiple bonds, i.e., double and TRIPLE bonds with not only carbon but with atoms of other elements like oxygen, nitrogen, etc. Due to its small size, the carbon atom can form multiple bonds, i.e., double and triple bonds with not only carbon but with atoms of other elements like oxygen, nitrogen, etc. The formation of these multiple bonds gives rise to a VARIETY in the carbon COMPOUNDS.

ic product of water is the product of concentration of OH− and H+ ions. Due to the self-ionization of water it can act as both acid and BASE. When an acid or base is added to the water the IONIC product of the water REMAINS constant, but the concentration of ions changes for different types of solution.

znco3 is a normal salt.Explanation:As normal salt is a salt formed by the COMPLETE replacement of replaceable HYDROGEN atoms from an acid so $N{a_3}P{O_4}$is a normal salt.

tion:AS with all these PROBLEMS, we assume (for simplicity) 100⋅g of UNKNOWN compound.And thus there are 85.7%×100⋅g12.011⋅g⋅mol−1 with respect to CARBON, i.e. 7.14⋅mol⋅C And 14.3%×100⋅g1.00794⋅g⋅mol−1 with respect to hydrogen, i.e. 14.1⋅mol⋅H .And thus the empirical formula , the simplest whole number ratio that defines constituent elements in a SPECIES is CH2 .Now the molecular formula is alway a whole number multiple of the empirical formula :empirical formula×n = molecular formula So (12.011⋅g⋅mol−1+2×1.00794⋅g⋅mol−1)×n=84⋅g⋅mol−1.So n=6 , and molecular formula = 6×CH2 = C6H12

nitude of the equilibrium constant, K, INDICATES the extent to which a reaction will proceed: If K is a large NUMBER, it MEANS that the equilibrium concentration of the products is large. In this CASE, the reaction as written will proceed to the right (resulting in an increase in the concentration of products)PLEASE mark me brain mark list

Carbon is TETRAVALENT elementExplanation:The reason why carbon is tetra VALENT is because there are 4 ELECTRONS in it valence shell which allows him NEITHER to donate or nor to get an electron but to share them due to which most covalent compounds contain carbon..It has electronic configuration of -- 1s2 2s2 2p6 3s2 3p2Mark it as the brainliest dear

The Hess's law states that the total enthalpy change during a complete CHEMICAL reaction is the same regardless of the path taken by the chemical reaction. ... Thus, it can be clearly SEEN that no matter what path we follow, the total enthalpy change in the reaction is always the same.Explanation:PLEASE mark me as brainliest.

Hess's law of heat SUMMATION states that if two or more thermochemical EQUATIONS can be added TOGETHER to give a final equation, then the heats of reaction can ALSO be added to give a heat of reaction for the final equation. Explanation:Please mark me as brainliest.
