Reaction of zinc metal in copper sulfate solution.

[tex]\begin{array}{ll}\text { Oxidation : } & \mathrm{Zn}(s) \rightarrow \mathrm{Zn}^{2+}(a q)+2 e^{-}\\\text {Reduction : } & \mathrm{Cu}^{2+}(a q)+2 e^{-} \rightarrow \mathrm{Cu}(s) \\\hline \text { Full Reaction : } & \mathrm{Zn}(s)+\mathrm{Cu}^{2+}(a q) \rightarrow \mathrm{Zn}^{2+}(a q)+\mathrm{Cu}(s)\end{array}[/tex]

Zinc is listed above copper on the activity series, this means that zinc is more easily oxidized than copper. That is why copper(II) ions can act as an oxidizing agent when put into contact with zinc metal. Ions of any metal that is below zinc, such as lead or silver, would oxidize the zinc in a similar reaction.

Answer:

Moles of tin = 0.37 mol

Explanation:

Given data:

Mass of tin oxide = 50 g

Moles of tin = ?

Solution:

Number of moles of SnO:

Number of moles = mass/molar mass

Number of moles = 50 g/ 134.71 g/mol

Number of moles = 0.37 mol

We can see there is only one mole of Sn is present in one mole of tin oxide.

Thus in 0.37 mol  of tin oxide,

0.37 mol × 1 = 0.37 mol of tin

Answer:

Light

Explanation:

Light is a good example of invisible particles. We cannot see light particles aka photon. We only know the light is present by the objects we see. Because we can only see objects when light reflects from them on our eyes.

Answer:

Normality of KOH = 0.1062 N

Note: The given question is not clearly stated. A related question below is answered and explained;

What is the NORMALITY of a solution of KOH if 45.18 mL are required to neutralize 0.3g of pure oxalic acid H2C2O4 . 2H2O?

Explanation:

Equation of the reaction: 2KOH + H₂C₂O₄.2H₂O --> K₂C₂O₄ + 4H₂O

molar mass 0f KOH = 56 g/mol; molar mass of H₂C₂O₄.2H₂O = 126 g/mol

Number of moles of in 0.3 g of H₂C₂O₄.2H₂O = mass/molar mass

number of moles = 0.3 g / 126 g/mol = 0.0024 moles

From the equation of reaction, 2 moles of KOH are required to neutralize 1 mole of H₂C₂O₄.2H₂O

Number of moles of KOH required to neutralize 0.0024 moles of H₂C₂O₄.2H₂O = 2 * 0.0024 = 0.0048 moles

Molar concentration of 45.18 mL solution of KOH containing 0.0048 moles of  KOH = number of moles/volume (L)

molarity of KOH solution = (0.0048/45.18 mL) * (1000 mL/1 L) = 0.1062 mol/L

Normality = n * molarity

where is the number of moles of OH⁻ ions produces from  mole of KOH = 1

Normality of KOH = 1 * 0.1062

Normality of KOH = 0.1062 N

#1 - A pure substance is either an element or a compound, making it different from a mixture. A sample of matter that has specific chemical and physical properties is the only one that fits here.

#2 - A pure substance is either an element or a compound, making it different from a mixture. Water is a compound, and thus this would be true.

#3 - An atom is the smallest unit of an element that keeps the properties of that element. Just refer to its definition.

#4 - A molecule is two or more atoms held together by chemical bonds . Again, just refer to its definition.

#5 - A chemical bond is the attractive force that holds atoms together . Jus refer to its definition.

#6 - Molecules are most definitely not all the same size, especially given the huge number of them. This would be false.

#7 - A compound is a pure substance made up of two or more different types of atoms joined by chemical bonds . Just refer to its definition.

#8 - Compounds always form in a fixed ratio, so this would be false.

#9 - If by directly, the problem means with the naked eye, this would be true.

#10 - False. It's reversed.

#11 - A crystal is a substance in which the particles are arranged in an orderly, geometric, and repeating pattern . Just refer to its definition.

#12 -True; to be more specific, they are covalent network solids.

Explanation:

B. Kids should go to school for 12 years.

Scientific statements are those statements that must be falsifiable which means that able to be proven false while on the other hand, tautology is a statement that is true. The sun revolves around the earth” is an example of scientific statement because this statement can be falsifiable in the light of evidences and researches. Hypothesis is a statement that may be true or false. We can verify it by doing experiments.

So we can conclude that option B is the sentence that represents a scientific statement.

on the left side of the arrow

The reactants in the chemical equation located on the left side of the arrow. Option D is correct.

The arrow in the chemical equation represents the direction of the chemical reaction, and it separates the reactants from the products.

A chemical equation is a symbolic representation of a chemical reaction, showing the starting materials (reactants) and the resulting substances (products). The general form of a chemical equation is as follows:

Reactants → Products

Reactants: The reactants are the substances present at the beginning of the chemical reaction. They are the starting materials that undergo a chemical change or reaction to produce new substances. Reactants were written on the left side of the arrow.

Arrow: The arrow in the chemical equation points from the reactants to the products, indicating the direction of the reaction. It symbolizes the transformation of reactants into products during the chemical reaction.

Products: The products are the substances formed as a result of the chemical reaction. They are the new compounds or elements that are produced by rearranging the atoms of the reactants. Products were written on right side of the arrow.

For example, let's consider the combustion of methane (CH₄) in oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O):

CH₄ (methane) + 2 O₂ (oxygen) → CO₂ (carbon dioxide) + 2 H₂O (water)

In this chemical equation, methane (CH₄) and oxygen (O₂) are the reactants, and they are located on the left side of the arrow. The products, carbon dioxide (CO₂), and water (H₂O), are located on the right side of the arrow.

Hence, D. is the correct option.

Answer:

Mass = 12.27 g

Explanation:

Given data:

Mass of NaCl are required = ?

Volume of AgNO₃ = 346 mL (346 mL× 1L/ 1000 mL = 0.346 L)

Molarity of AgNO₃ = 0.607 M

Solution:

Chemical equation:

NaCl  + AgNO₃     →    NaNO₃ + AgCl

Number of moles of AgNO₃:

Molarity = number of moles / volume in L

0.607 M = number of moles / 0.346 L

number of moles =  0.607 M × 0.346 L

number of moles =  0.21 mol

now we will compare the moles of NaCl and AgNO₃.

                       AgNO₃         :          NaCl        

                           1                :            1

                       0.21              :            0.21

Mass of NaCl:

Mass = number of moles × molar mass

Mass = 0.21 mol × 58.44 g/mol

Mass = 12.27 g

Hot springs are hot because of geothermal heat.  The Hot springs are acidic because hydrogen sulfide and carbon dioxide get in touch with water they evaporate which causes acid.

Explanation:

Ionic and covalent bonds can occur in substances that have a repeating lattice structure.

Ionic bonds are formed when an atom donates electron (s) to another atom. Covalent bonds, on the other hand, are formed when two atoms share electrons to complete their octet states.

Ionic compounds are formed from a combination of metal and non-metal atoms. They usually have crystalline lattice structures with high melting points.

Covalent compounds are formed between non-metal atoms. They can also have lattice structures but generally have lower melting points because the forces holding the molecules together are weaker.

The percent  by volume of a solution

Solution

Percent Volume (% v/v) : volume (ml) of solute/100 ml of solution ⇒ ratio of the volume of the solute to total volume of the solution

[tex]\tt \%solute(v/v)=\dfrac{solute~volume}{solution~volume}\times 100\%[/tex]

solute= Ethanol

solvent=water

Solution = solute+solvent

Total volume of the solution :

[tex]\tt =volume~of~Ethanol+solume~of~water\\\\=50~ml+210~ml\\\\=260~ml[/tex]

Percent by volume :

Explanation:An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms. ... Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals.      

Answer:

Explanation:

Given data:

Mass of alcohol = 400 g

Specific heat capacity of alcohol = 2.43 J/g°C

Initial temperature of alcohol = 16°C

Mass of water = 400 g

Specific heat capacity of water = 4.19 J/g°C

Initial temperature of water = 85°C

Final temperature of mixture = ?

Solution:

Equation:

m₁c₁ (T₂-T₁ ) = m₂c₂(T₂-T₁)

by putting values,

400 × 4.19  × (T₂ -  85°C) = 400 × 2.43  × (T₂ - 16°C)

1676  × (T₂ -  85°C) = 972 × (T₂ - 16°C)
