Answers

Answer 1

The difference between the calculated voltage (based on standard potentials) and the actual voltage required to cause electrolysis is called overvoltage.

Electrolysis

Electrolysis is the technique of causing a chemical change in a substance by passing an electric current through it. The substance either loses or gets an electron during the chemical transition (oxidation or reduction). The procedure is carried out in an electrolytic cell, a device made up of positive and negative electrodes that are kept apart and submerged in a solution with ions that are both positively and negatively charged. The chemical that needs to be converted might either be dissolved in the solution or could form the electrode. The negatively charged electrode (cathode) receives electrical current (i.e., electrons), which travels there and combines with the components of the solution to convert them (reduced).

What is one off the differences in how the leading and lagging strands of dna molecules synthesize?

Answers

The basis of the difference between the leading and lagging strand is that DNA polymerase can join new nucleotides only to the 3' end of the growing strand.

The leading strand is the new DNA strand that continually extends from 5' to 3'. On the lagging strand, Okazaki fragments develop and are linked by DNA ligase activity. DNA polymerase can only attach new nucleotides to the 3' end of the developing strand, which forms the basis of the distinction between the leading and lagging strands.

Therefore, "DNA polymerase can link additional nucleotides exclusively to the 3' end of the developing strand" is the appropriate response.

Is copper and silver nitrate a physical change or Chemical change

Answers

Explanation:

One of the most fascinating chemical experiments is the reaction between silver nitrate and copper wire in water. Characterised by fractal-like precipitates, this experiment is a stunning example of a simple redox reaction.

Copper reacting with silver nitrate is a chemical change. In a chemical change, new substances are formed with different chemical properties.

Copper (Cu) is a metal, and silver nitrate is a compound made of silver (Ag), nitrogen (N), and oxygen (O).When copper is added to silver nitrate, a reaction occurs. The copper atoms react with the silver nitrate molecules, resulting in the formation of new substances.

The reaction produces copper nitrate  and silver (Ag) as products.Copper nitrate is a compound formed by the combination of copper, nitrogen, and oxygen, while silver remains unchanged.

The color of the solution changes, indicating a chemical reaction has taken place. Copper nitrate is usually a blue-green color, while silver is a metallic silver color.The chemical properties of the substances involved in the reaction are altered. Copper, being a metal, is malleable and conducts electricity, whereas copper nitrate is a compound and does not possess these properties.

Thus, the reaction between copper and silver nitrate is a chemical change because new substances with different properties are formed.

The percentage composition of an organic acid is found to be 39.9% C, 6.7% H, and 53.4% O. The molar mass for the compound is 60.0g/mol. What is the molecular formula

Answers

Answer:

C₂H₄O₂

Explanation:

To find the molecular formula of the organic acid, you need to (1) determine the mass of each element (from the given percents), then (2) convert grams of each element to moles (via atomic masses), then (3) find the empirical formula, and then (4) find the molecular formula.

(Step 1)

39.9% C -----> 39.9 g C

6.7% H -----> 6.7 g H

53.4% O -----> 53.4 g O

(Step 2)

Atomic Mass (C): 12.011 g/mol

Atomic Mass (H): 1.008 g/mol

Atomic Mass (O): 15.988 g/mol

39.9 grams C             1 mole
----------------------  x  ----------------------  = 3.32 moles C
                                12.011 grams

6.7 grams H              1 mole
--------------------  x  ---------------------  =  6.65 moles H
                              1.008 grams

53.4 grams O              1 mole
----------------------  x  ----------------------  =  3.34 moles O
                                15.998 grams

(Step 3)

The empirical formula is made up of the lowest possible amount of each element in the molecule. These amounts can be found by dividing the molar value of each element by the smallest molar value. In this case, the smallest molar value is 3.32 moles C. The calculated values make up the subscripts in the empirical formula.

3.32 moles C / 3.32  =  1 mole C

6.65 moles H / 3.32  =  2 moles H

3.34 moles O / 3.32  =  1 mole O

Empirical Formula: CH₂O

(Step 4)

To find the molecular formula, you first need to determine the molar mass of the empirical formula. Once you have this value, you need to determine how much you need to scale the formula up by. In this case, the molar mass of the empirical formula is half of the molar mass of the molecular formula. Therefore, you need to multiply the amount of each element in the molecule by 2.

Molar Mass (CH₂O): 12.011 g/mol + 2(1.008 g/mol) + 15.998 g/mol

Molar Mass (CH₂O): 30.025 g/mol

30.025 g/mol x 2 = 60.05 g/mol

CH₂O x 2 = C₂H₄O₂

Two liquids are in a graduated cylinder - liquid a has a density of 1.004 g/cm3 and liquid b has a density of 0.6223 g/cm3 . assuming that they do not mix, which liquid is on top and which liquid is on bottom? where would you expect to find the plastic cube from question #2 if it is dropped into the graduated cylinder with these two liquids?

Answers

Liquid B is expected to be at the top while liquid A is found at the bottom.

What is density?

The term density has to do with the ratio of the mass of a substance to its volume. Now given that the density of a substance actually shows how much heavy the substance is, it is not difficult to understand that a material that has a low density will flat at the top of a material that has a lower density.

Here we are told that the two liquids do not mix. If they do not mix then it follows that they must have formed a two phase system in which one is at the top of the other. The one that is at the top must have the lower density.

Thus, liquid B is expected to be at the top while liquid A is found at the bottom. From the density of the plastic cue, the cube will be at the top.

Considering the Charles's law, the volume at 22.8 °C is 10.9978 L.

Charles's law

Charles's law establishes the relationship between the temperature and the volume of a gas when the pressure is constant.

Charles's law says that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases, and as the temperature decreases, the volume of the gas decreases. That is, the volume is directly proportional to the temperature of the gas.

Mathematically, Charles' law is a law that says that when the amount of gas and pressure remain constant, the ratio between volume and temperature will always have the same value:

[tex]\frac{V}{T} =k[/tex]

Considering an initial state 1 and a final state 2, it is fulfilled:

[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]

Volume at -22.8 °C

In this case, you know that:

V1= 12 LT1= 0 °C= 273 KV2= ?T2= -22.8 °C= 250.2 K

Replacing in Charles's law:

[tex]\frac{12 L}{273 K} =\frac{V2}{250.2 K}[/tex]

Solving:

V2= [tex]250.2 K x\frac{12 L}{273 K}[/tex]

So, it will take two HCl to neutralize one Ba(OH)2.

Hence, equation for this reaction is

2HCl(aq) + Ba(OH)2(aq) ===> BaCl2(aq) + 2H2O(l).

Which of the following choices represents a balanced chemical equation?

Answers

Answer:

the correct answer: 2Ca3(PO4)2 + 6SiO2 -> P4O10 + 6CaSiO3

Explanation:

Ionic compounds are ______ at room temperature and generally have ______ melting and boiling points.

Answers

Thus all ionic compounds are solids at room temperature and generally they have very high melting and boiling points.

There are strong electrostatic attractive forces between the positive and negative ions in ionic solids. These extremely powerful forces must be overcome in order to melt the solid. As a result, all ionic compounds are solids at room temperature and have extremely high melting and boiling points.

E.g. MgF2 has a melting point of. 1261°C and a boiling point of 2239°C

The strong forces between the ions are difficult to break, which also explains why ionic compound crystals are hard. Ionic substances form massive ionic lattices with oppositely charged ions.

What are the characteristics of ionic compounds?

Ionic compounds are made up of charged particles known as ions. It has a massive lattice structure with strong electrostatic attraction forces. Giant ionic lattices are regular structures found in ionic compounds.

In Chemistry, some examples of ionic compounds are:

Sodium chloride.Sodium oxide.Lithium chloride.Aluminum chloride.Potassium bromide.
