In redox reactions, an oxidation half reaction shows the oxusetoon occurring while the reduction half reaction shows the reduction occurring in the overall reaction.

Redox reactions are reactions in which oxidation and reduction reactions occur together to the same extent.

A redox reaction can be split into two half oxidation and reduction reactions.

The half reactions of the given reactions are shown below:

Overall reaction;

[tex]A. Mg(s) + CoBr_2(aq) ⟶ MgBr_2(aq) + Co(s) \\ [/tex]

Oxidation half reaction:

[tex]Mg (s) ---> Mg ^{2+}(aq)[/tex]

Reduction half reaction:

[tex]Co^{2+} (aq) ---> Co (s)[/tex]

B. Overall reaction

[tex]Cu(s) + 2AuCl(aq) ⟶ CuCl_2(aq) + 2Au(s) \\ [/tex]

Oxidation half reaction:

[tex]Cu(s) ---> Cu^{2+}(aq)[/tex]

Reduction half reaction:

[tex]2Au^{+}(aq) ---> 2 Au (s)[/tex]

Therefore, redox equations can be spilt into oxidation and reduction half reactions.

Based on the data provided, the equation of the reaction is:

Enthalpy of neutralization is the heat change when one mole of hydrogen ions from an acid reacts with one mole of hydroxide ions from an alkali to produce one mole of water.

The equation of the reaction of KOH and HNO3 is given below:

[tex]KOH + HNO_3 \rightarrow KCl + H_2O[/tex]

1 mole of KOH reacts with 1 mole of HNO3 to produce 1 mole of water.

Volume of KOH = 30 mL = 0.03 L

moles of KOH = 0.03 × 0.234 = 0.00702 moles

Therefore, 0.00702 moles of water are produced

Heat produce = mass × specific heat × temperature difference

Volume of solution = 60 mL

density of solution = 1.0 g/mL

mass of solution = 60 mL × 1.0 g/mL = 60 g

Heat produced = 60 × 4.18 × 5.6

Heat produced = 1404.48 J

Enthalpy of neutralization = 1404.48 J/0.00702 moles

Enthalpy of neutralization = 200068.37 J/mol

Enthalpy of neutralization = 200 kJ/mol

Answer:

A - Cinder cone

B - Shield

C - Composite

Explanation:

Cinder cone volcanoes are formed when the volcano explodes and all the lava soldifies and falls steeply upon the sides of the mountain and forms cinders.

Shield volcanoes form when a centralized vent produces low-viscosity flows over a long period of time

Composite volcanoes are also called stratovolcanoes. They form when different types of eruptions deposit different materials around the sides of a volcano. Alternating eruptions of volcanic ash and lava cause layers to form. Over time these layers build up.

Answer:

About 64 grams of KClO₃.

Explanation:

Potassium chlorate dissociates according to the equation:
[tex]\displaystyle 2\text{KClO$_3$} \xrightarrow{\text{heat}} 2\text{KCl} + 3\text{O$_2$}[/tex]

To determine the amount of KClO₃ necessary to produce 25 grams of O₂, we can convert grams of O₂ to moles; moles of O₂ to moles of KClO₃;  and finally to grams of KClO₃.

The molecular weights of O₂ and KClO₃ are 16.00 g/mol and 122.55 g/mol.

Hence:

[tex]\displaystyle 25\text{ g O$_2$} \cdot \frac{1\text{ mol O$_2$}}{32.00\text{ g O$_2$}} \cdot \frac{2\text{ mol KClO$_3$}}{3\text{ mol O$_2$}} \cdot \frac{122.55\text{ g KClO$_3$}}{1\text{ mol KClO$_3$}} = 64\text{ g KClO$_3$}[/tex]

In conclusion, about 64 (to two significant digits) grams of KClO₃ is needed.

Answer:

CS2 + 3O2 -> CO2 + 2SO2

Explanation:

The rate of reaction of the magnesium ribbon in the dilute hydrochloric acid is 0.067 g/s.

Rate of reaction is the rate at which a reaction takes place. It is proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.

Mg(s) + 2HCI = MgCl2(aq) + H2(g)

Rate of reaction = mass of magnesium reacted/time taken

Rate of reaction =  2 g /30 s

Rate of reaction =  0.067 g/s

Thus, the rate of reaction of the magnesium ribbon in the dilute hydrochloric acid is 0.067 g/s.

The Ksp shows the extent of solubility of a substance in another. The solubility of the compound is 1.2 * 10^-7 M.

The term solubility shows the extent to which a substance dissolve in solution. The solubility of a substance is often typified by the Ksp of the substance.

Now;

ScF3(s) ⇄Sc^+(aq) + 3F^-

Ksp = [Sc^+] [F^-]^3

Ksp = x (3x)^3

Ksp = 27x^4

x = 4√5.81×10^−24/27

The ammonia molecule is a trigonal pyramidal and has 4 sp3 orbitals

Explanation:

Nitrogen has 5 valence electrons, Hydrogen takes up 3 bonds and there's a lone pair on top, and the gemoetry is structured in a way so the hydrogen atoms are facing down away from the lone pair and evenly spaced out between the other hydrogens.

The volume of gas occupied by 11 grams of nitrogen dioxide gas at STP is 5.15 L.

Ideal gas equation of any gas will be writen as:

PV = nRT, where

P = standard pressure = 1 atm

V = volume = ?

R = universal gas constant = 0.082 L.atm/K.mol

T = standard temperature = 273K

n is the moles of gas which can be calculated by using below equation as:

n = W/M, where

W = given mass = 11g

M = molar mass = 46 g/mol

n = 11 / 46 = 0.239mol

On putting values on the above equation, we get

V = (0.23)(0.082)(273) / (1) = 5.15 L

Hence required volume of gas is 5.15 L.

The molarity of the sample of the salt dissolved in the solution is determined as 0.1 M.

The molarity of the sample is the number of solutes dissolved in liters solution.

molarity = number of moles/Liters of solution

molarity = 0.2 moles / 2L

molarity = 0.1 M

Thus, the molarity of the sample of the salt dissolved in the solution is determined as 0.1 M.
