diatomic elements are important. what makes them different from other elemental substances?

Answers

Answer 1

Other elemental substances in that they consist of two atoms of the same element, bonded together.

What is Diatomic elements?

Diatomic elements are chemical elements that exist in the form of two atoms held together by covalent bonds. The most common elements that exist as diatomic molecules are hydrogen, oxygen, nitrogen, fluorine, chlorine, bromine, and iodine. These elements are found in nature and play important roles in the formation of compounds used in everyday life.

This bond is usually covalent in nature, and the two atoms form a stable molecule. This type of molecule is very stable and present in the form of gas, at room temperature and pressure. Examples of diatomic elements are hydrogen, oxygen, nitrogen, fluorine, chlorine, and bromine. Due to the fact that these elements are already in a stable, two-atom form, they exhibit different chemical and physical properties than other elements. For example, diatomic oxygen is highly reactive and can easily combine with other elements, while diatomic nitrogen is relatively inert. This difference in reactivity is due to the fact that the two atoms in the diatomic form share electrons more easily than atoms in other elemental forms.

What is the function of a climograph?

Answers

Answer:

A climograph is a graphical representation of the climate of a particular location over a period of time. It typically shows the average temperature and precipitation for a specific location over the course of a year, with the temperature plotted on the y-axis and the months of the year plotted on the x-axis.

The primary function of a climograph is to provide a visual representation of the climate of a particular location, which can be useful for understanding the weather patterns and temperature ranges that are typical for that location. Climographs can also be useful for comparing the climate of different locations, as they provide a convenient way to see how temperature and precipitation patterns differ from one place to another.

Climographs show monthly average temperatures and precipitation totals on a single graph. Rather than showing measured data for specific time periods—like the graphs you generated in Part A—climographs show long term averages for all 12 months of the year.

What is amino acids?

Organic substances that possess both amino and carboxylic acid functional groups are known as amino acids. Although hundreds of amino acids occur in nature, the alpha-amino acids that constitute proteins are by far the most significant. The genetic coding contains only 22 alpha amino acids. Amino acids are chemicals that make proteins when they combine. The building blocks of life are amino acids and proteins. Amino acids are left over after proteins are digested or broken down. To support the body, the human body utilizes amino acids to build proteins: Food should be broken down.

Here,

As the pH is given as 7.4 and pK of His is given as 6.00. There will occur a positive charge on His when it's pH < pK therefore, it is neutral at the given pH.

As the pK value of Lys is 10.53 that is greater than the pH of 7.40. Therefore, charge on Lys is positive.

As the pK value of Asp is 3.65 which is less than the pH value of 7.40. Hence, Asp has a negative charge.

Therefore, we can conclude that His and Lys are deprotonated but Asp will be protonated.

The activation energy of a first order reaction is 83. 5kJ/mol. The rate constant is 3. 54x10^-5s^-1 at 45 C. What is the rate constant at 65 C?

Answers

The rate constant at 65 C is k65= 4.8 x 10^-5 s^-1 .Below is the explanation for the answer

To find the rate constant at a different temperature, you can use the Arrhenius equation, which relates the rate constant to the activation energy and the temperature. The equation is:

k = A * e^(-Ea/RT)

where
k is the rate constant,
A is the pre-exponential factor (also known as the frequency factor),
Ea is the activation energy,
R is the universal gas constant,
T is the absolute temperature.

We are given that the activation energy is 83.5 kJ/mol and the rate constant at 45 C is 3.54 x 10^-5 s^-1. To find the rate constant at 65 C, we can substitute these values into the equation and solve for k.

k = A * e^(-Ea/RT)
k = 3.54 x 10^-5 s^-1 * e^(-(83.5 kJ/mol) / (8.314 J/mol*K * (45 + 273.15 K))

However, A is a constant that we don't know. To find the rate constant at 65 C, we can use the fact that the rate constant is proportional to the temperature. Therefore, we can find the ratio of the rate constants at 65 C and 45 C, then multiply it by the rate constant at 45 C to find the rate constant at 65 C.

k65/k45 = (T2/T1)^n
where
k65 is the rate constant at 65 C
k45 is the rate constant at 45 C
T2 is the temperature in Kelvin (65 + 273.15)
T1 is the temperature in Kelvin (45 + 273.15)
n is the order of the reaction, which is 1 in this case

we can find the rate constant at 65 C is:
k65 = k45 (T2/T1)^n
k65 = 3.54 x 10^-5 s^-1 * ( (65 + 273.15) / (45 + 273.15) )^1

k65= 4.8 x 10^-5 s^-1

C. volume (ml) of 10.00 M copper(II) nitrate that must be diluted with water to prepare 750.0 ml of a 2.500 M solution (enter to 4 significant figures)
D. Are the following instructions for diluting a 10.0 M solution to a 1.00 M solution correct: "Take 100.0 mL of the 10.0 M solution and add 900.0 mL water"? enter either true or false

Answers

(A) Vol. of solvent is 119.8 ml, (B) Molarity (M) of sol. is 5.00 M, (C) V1 of copper nitrate solution is 187.5 ml, (D) The instruction given is false.  

(A). To calculate the volume (ml) of a 2.25 M potassium hydroxide solution that contains 15.0 g of solute, we can use the formula:

The unit of measurement for molarity (M) is moles of solute per liter of solvent.

Rearranging the formula to solve for liters of solvent:

Molecularity = moles of solute / liters of solvent (M)

We know that the molar mass of potassium hydroxide (KOH) is 56.1 g/mol. To find the moles of solute, we can divide the given mass (15.0 g) by the molar mass of KOH:

15.0 g / 56.1 g/mol = 0.2679 moles

Now we can plug this value into the formula above:

Liters of solvent = 0.2679 moles / 2.25 M

Liters of solvent = 0.1198 L or 119.8 ml (rounded to 3 significant figures)

(B). To calculate the molarity of a solution containing 1.25 moles of glucose in 250. ml of solvent, we can use the formula:

The unit of measurement for molarity (M) is moles of solute per liter of solvent.

Plugging in the given values:

Molarity (M) = 1.25 moles / 0.250 L

Molarity (M) = 5.00 M

(C). To calculate the volume of a 10.00 M copper(II) nitrate solution that must be added to water to prepare 750.0 ml of a 2.500 M solution, we can use the formula:

M1V1 = M2V2

Where M1 and V1 are the concentration and volume of the original solution, and M2 and V2 are the concentration and volume of the final solution.

We know that the final solution has a volume of 750.0 ml and a concentration of 2.500 M, so we can plug in these values for V2 and M2:

M1V1 = 2.500 M x 750.0 ml

Now we can solve for V1 (the original volume) by rearranging the formula:

V1 = M2V2 / M1

V1 = (2.500 M x 750.0 ml) / 10.00 M

V1 = 187.5 ml (rounded to 4 significant figures)

(D). The instructions "Take 100.0 mL of the 10.0 M solution and add 900.0 mL water" are not correct for diluting a 10.0 M solution to a 1.00 M solution.

To achieve this dilution, you would need to take a smaller volume of the 10.0 M solution and add a larger volume of water, because the final volume should be larger than the starting volume.

For example, you could take 10.0 mL of the 10.0 M solution and add 90.0 mL of water, which would give you a final volume of 100.0 mL and a concentration of 1.00 M. The instruction given above is false.

Diatomic elements are elements that exist in nature as molecules made up of two atoms of the same element, such as H2, O2, N2, and F2.

A diatomic atom is one that cannot exist on its own. There are no single O atoms floating around in the sky. Because O atoms must exist in pairs, oxygen occurs as O2. These atoms are too unstable to live on their own.

This elements are different from other elemental substances because they are composed of multiple atoms of the same element, rather than a single atom or a mixture of different elements.
