calculate the ratio of the fundamental frequencies for ethylene and deuterated ethylene

Metal atoms form metallic connections. Ionic bonds link metals to non-metals, whereas metallic bonds link a large number of metal atoms.

What distinctions may be made between metals and nonmetals?

The major distinction between metals and non-metals is that metals are frequently hard and effective heat- and electricity-conductors. Non-metals, however, are brittle and inadequate heat and electrical conductors.

While non-metals take electrons to produce anions, metals lose electrons and form cations. These ions' electrical attraction to one another causes them to form extraordinarily potent ionic connections. As a result, an ionic bond exists between a metal and a nonmetal.

Explanation:

Because boiling point is independent of liquid volume, the boiling point would not vary.

What is boiling point  ?

A liquid's boiling point changes depending on the pressure being applied; the normal boiling point is the temperature at which the vapor pressure is equal to the average atmospheric pressure at sea level (760 mm [29.92 inches] of mercury). Water boils at sea level at 100° C.

The temperature at which a liquid's vapor pressure equals the pressure around it and the liquid turns into a vapor is known as the boiling point of a substance

A liquid's boiling point varies depending on the atmospheric pressure in the area. The boiling point of a liquid is lower in a partial vacuum than it is at atmospheric pressure. A liquid's boiling point is lower under low pressure than it is under air pressure. As a result, water boils at 99.97 °C (211.95 °F) at sea level but at 93.4 °C (200.1 °F) at 1,905 m (6,250 ft) altitude under standard pressure. Various liquids will boil at different temperatures at a given pressure.

Because boiling point is independent of liquid volume, the boiling point would not vary.

In poorly sorted sediments, those with a larger range of grain sizes, the finer grains tend to fill the spaces between the larger grains, resulting in lower porosity. Primary porosity can range from less than one percent in crystalline rocks like granite to over 55% in some soils.

Explanation:

Explanation:

AH is negative because the reaction gives out heat (exothermic).

AS is negative because the total entropy of the reactants is greater than that of the products (there are 4 moles of gas on reactant side compared to only 1 mole on the product side). Thus, the reactants are said to be "messier" than the products.

AG is negative at lower temperatures because at low temperatures, -TAS is more negative, resulting in the negative sign of AG.

Explanation:

The image represent in malleable property of metal.

The image possibly represents the photoelectric effect of a metal, which is when it emits electrons after being exposed to electromagnetic radiation. Metals are also characterized by physical properties such as conductivity, malleability, metallic luster, and metallic bonding.

Based on your question, the image possibly represents the photoelectric effect, a key property of metals. This phenomenon occurs when a metal surface exposed to electromagnetic waves of a certain frequency absorbs radiation and emits electrons. These emitted electrons are called photoelectrons. Metals can also exhibit free electron model behavior, where electrons freely roam within the metal structure.

Metals possess unique physical properties like conductivity, malleability, and metallic luster. Malleability refers to the metal's ability to deform without breaking, while conductivity refers to the metal's ability to transfer heat or electricity. A metallic luster gives metals their characteristic shiny appearance.

Finally, metals are also known for their metallic bonding—a unique force that holds together the atoms within a metallic solid. Metallic bonding gives rise to many useful and varied bulk properties of metals.

The value of E°cell for the given balanced redox reaction is -1.23 V.

To calculate the standard cell potential (E°cell) for the given balanced redox reaction, we need to use the standard reduction potentials (E°red) of the half-reactions involved.

The balanced redox reaction provided is:

O2(g) + 2H2O(l) + 4Ag(s) → \(4OH^-\)(aq) + \(4Ag^+\)(aq)

We can split this reaction into two half-reactions:

Half-reaction 1: O2(g) + 2H2O(l) + \(4e^-\)→ \(4OH^-\)(aq)

Half-reaction 2: 4Ag(s) → 4\(Ag^+\)(aq) + \(4e^-\)

The standard reduction potential (E°red) for half-reaction 1 is 0.40 V (from tables).

The standard reduction potential (E°red) for half-reaction 2 is 0.80 V (from tables).

To calculate E°cell, we subtract the reduction potential of the anode (where oxidation occurs) from the reduction potential of the cathode (where reduction occurs):

E°cell = E°red(cathode) - E°red(anode)

E°cell = 0.80 V - 0.40 V

E°cell = 0.40 V

However, since the reaction is written in the opposite direction (reverse of the cell notation), the sign of E°cell is flipped:

E°cell = -0.40 V

Rounding to two decimal places, the value of E°cell for the given balanced redox reaction is -1.23 V.

According to the linear conversion equation20 degrees Celsius is equivalent to 68 degrees Fahrenheit.

To convert a temperature from degrees Celsius to degrees Fahrenheit, we follow the given formula. Let's break down the steps:

1. Multiply the temperature in degrees Celsius by 1.8.

  This step accounts for the conversion factor between Celsius and Fahrenheit. The value 1.8 represents the ratio of the size of a degree Fahrenheit to a degree Celsius.

2. Add 32 to the result.

  The addition of 32 is necessary because the zero point on the Fahrenheit scale is 32 degrees below the zero point on the Celsius scale. This adjustment aligns the two scales properly.

By combining these steps, we obtain the linear equation: F = 1.8C + 32, where F represents the temperature in degrees Fahrenheit and C represents the temperature in degrees Celsius.

Using this equation, we can convert any given temperature from Celsius to Fahrenheit. For example, if we have a temperature of 20 degrees Celsius, we can substitute C = 20 into the equation:

F = 1.8(20) + 32

F = 36 + 32

F = 68

The name of the organic compound is 2-methyl pentane. The given organic compound is a five-carbon system with a substitution at the C-2 carbon. The naming of an organic compound is done according to the rules given by IUPAC.

The given organic compound has 5 carbon in its main chain. So It has the root word Pent. Since, all the bonds are single bonds, the organic compound is saturated, hence it has the suffix -ane. Hence the unsubstituted straight chain is pentane.

Numbering is done from right to left, because when the numbering is from right to left, the substituted carbon gets C-2, when it is numbered from left to right, the substituted carbon gets C-4. So the numbering is from the right and the substituted carbon is C-2. The substituent is a single carbon system, a methyl substituent. So the organic compound is named 2-methyl pentane .

Direct contact between objects causes conduction or heat transfer. The heat is transferred inside the fluid during convection. Heat transfer in radiation happens by electromagnetic waves without the use of particles.

First, ascertain whether the two things are in contact. If they are, conduction is how heat is transferred between them. Determine whether there is a fluid medium, such as a liquid or gas, connecting the items if they are not in contact.

Evidence of heat transport is apparent. Convection is the phenomenon that causes the air to shimmer over radiators. Conduction is the phenomenon that causes you to feel warm when you place your hand on a spoon that has been sitting in a hot bowl of soup (radiation).

It takes approximately 100.704 years (since 1964) until only 9 percent of the original amount of radioactive strontium-90 absorbed remains.

The half-life of radioactive strontium-90 is given as 29 years, which means that every 29 years, the amount of radioactive strontium-90 is reduced by half.

To find the number of years it takes until only 9 percent of the original amount remains, we can set up the following equation:

(0.5)^(t/h) = 0.09

Where:

t represents the number of years since 1964 (the initial time),

h represents the half-life of 29 years, and

0.09 represents 9 percent.

Let's solve for t:

(0.5)^(t/29) = 0.09

Taking the natural logarithm (ln) of both sides:

ln[(0.5)^(t/29)] = ln(0.09)

Using the logarithmic property: ln(a^b) = b × ln(a):

(t/29) × ln(0.5) = ln(0.09)

Dividing both sides by ln(0.5):

t/29 = ln(0.09) / ln(0.5)

t = 29 × (ln(0.09) / ln(0.5))

Using a calculator, we can find the value of t:

t = 29 × (-2.40794561 / -0.69314718)

t = 100.704
