How does acid react to water mixed with clorine eyedrops

Answer:

hydrochloric acid (HCl)

Explanation:

balanced equation: Ca(OH)2+2HCl -> CaCl2+2H2O

85.0/36=2.33 mol HCl

120/74=1.62 Ca(OH)2

2.33 mol HCl x 1 mol CaCl2/2 mol HCl = 1.165 mol CaCl2

1.62 mol Ca(OH)2 x 2 mol CaCl2/1 mol Ca(OH)2 = 3.24 mol CaCl2

Answer:

yh correct answer is A

Answer:

To determine whether a given single replacement will occur, you must use an “Activity Series” table. If the metal or the halogen is above the element it will replace based on the activity series, a single displacement reaction will occur. The video below summarizes an experiment conducted to compare the activities of three metals ( Mg, Cu and Zn ).

Explanation:

Single replacement reaction will occur if any more active specie will add on the solution.

Single displacement reactions are those reactions in which one element from the given molecule is displaced by some other element.

Generally displacement reactions are shown by metals when more reactive metal is added in the solution of any another metal. Then more reactive metal displaces the metal which is already present in the solution and reaction is taking place is shown by changing in color.

Hence single displacement reaction will occur when more reactive metal is added in any solution.

Answer:

The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.

Explanation:

Answer:

An acidic oxide reacts with water and produces acid. They are also called acid anhydride, which are oxides that react with water to form an acid, or with a base to form a salt. They are oxides of either nonmetal or of metals in high oxidation states. An oxide is a binary compound that we obtain upon the reaction of oxygen with other elements. Their chemistry can be systematically understood by taking an oxoacid and removing water from it until only an oxide remains. The resulting oxide belongs to this group of substances. Usually, it is the oxide of non-metals. For example, sulfurous acid (SO2), sulfuric acid (SO3), and carbonic acid (CO2) are acidic oxides. Thus, CO2 dissolves in water to give carbonic acid, and NO2 gives a mixture of nitrous and nitric acids. An inorganic anhydride (a somewhat archaic term) is an acid anhydride without an organic moiety.

Based on the dissolution equation of BaSO4, the solubility product, Ksp, expression of BaSO4 is: [Ba^{2+}] × [SO4^{2-}]

The solubility product, Ksp, of a substance is an equilibrium constant which expresses the product of the concentration of ions produced by a solute.

The solubility of a solute depends on temperature, thus solubility product also depends on temperature.

The balanced equation for the dissolution of barium sulfate is given below:

The solubility product for barium sulfate is given as;

The temperature change that indicates an increase in the average kinetic energy of the molecules in a sample is 255 K to 0°C.

Chemical reactions occur when particles of reactants react or collide with one another, hence, when particles collide faster, reaction also occurs faster.

One of the ways to make reactions occur faster i.e. increasing the average kinetic energy is by increasing the temperature.

The example that depicts an increase in temperature is 255K to 0°C, which is equivalent to 255K to 273K.

Species that have a lone pair of electrons often donate electrons by resonance while substituents that are electron deficient take away electrons by resonance.

The term resonace has to do with the movement of electron pairs in a molecule. Inductive effects has to do with the drawing of electron density towards an atom or bond.

The two effects depends on the nature of a substituent. For instance, species that have a lone pair of electrons often donate electrons by resonance while substituents that are electron deficient take away electrons by resonance.

The question is incomplete hence the exact nature of the substituents can not be determined.

In resonance, the species with lone pairs donate electrons while the substituent takes electrons away from another species when deficient by resonance.

When the electron donor or the withdrawal groups creates the electron density on the molecule then it is called the inductive effect. This results in the creation of permanent dipoles in the bonds of the molecules.

Atom attached to a benzene molecule with higher electronegativity than hydrogen atom then, it will be an acceptor while with lower electronegativity will be a donor.

The movement of the electron pair like lone pair and pi bond in a molecule by the delocalization is called the resonance effect. The electron donation and acceptance depend on the nature of the substituent molecule.

If the atom attached to the benzene molecule is electron-rich, it will be a donor, while the electron-deficient will accept the electron by the method of resonance effect.

Therefore, the nature of the substituent determines the resonance and the inductive effect.
