A burner system, a basket, and an envelope are components shared by all hot air balloons. The size and shape of the envelope, the deflation mechanism, the shape and design of the basket, and the arrangement, style, and number of burners are all different.

The balloon will sink if the pilot leaves the valve open long enough. In essence, the sole controls are heat to raise the balloon and ventilation to lower it.

The pilot opens the vent that allows air out of the balloon canopy after locating a good landing area. The balloon began to drop as a result.

A hole known as a parachute vent can be found at the top of a hot air balloon. Pulling a rope to open it causes heated air to be released, causing the balloon to drop. The pilot has complete control over how much hot air is injected into the balloon, enabling flawless control.

Explanation: Set up the equilibrium table, find x and from there find your Kc=(Co)^2*(O2)/(O2)^2

Answer: -40

Explanation:

equation:

t = 1.8t+32

move variable to one side

t x -1.8t=32

add like terms

-.8t = 32

change decimal to fraction

-4t/5 = 32

multiply 5 to both sides

-4t = 160

devide -4

t = -40

Law of conservation of mass states that in a closed system, the mass would be the same.

In a reaction, the compounds’ undergoing reaction is called reactants and the resultant of the reaction is called products.

Word equation uses words instead of chemical formulas. The skeleton equations use chemical formulas without mentioning the state of the compounds or the concentration. In balanced chemical reaction, mass and charge would be balanced.

Law of conservation of mass is similar to law of conservation of energy. It says that in a closed system, the mass would remain the same as mass is neither created nor destroyed.

[tex]H_{2}O[/tex]  →  [tex]H_{2} + O_{2}[/tex]

In this reaction, [tex]H_{2}O[/tex] is the reactant which has a mass of 18. H₂ and O₂ are the products with mass of 2 and 16 respectively.

In word equations, equation 1 can be written as

Water → Hydrogen + Water

In skeleton equation,

H₂0 → H₂ + O₂

In balanced chemical reaction,

2 H₂0 → 2 H₂ + O₂

The element's Atomic number , which has 5 protons, 6 neutrons, and 2 electrons (the atomic number is the number of protons) =  5

the number assigned to a chemical element according to its atomic number in the periodic system, which places the elements in ascending order of the number of protons in their nuclei. As a result, the atomic number is also the number of protons, which in a neutral atom is always equal to the amount of electrons.

Protons and neutrons are added to determine an element's mass number. The only number that may change while maintaining the identity of an element is the number of neutrons for that element (because the atomic number is the number of protons).

Mass number = protons + neutrons

Given:

5 protons,

6 neutrons

2 electrons

Atomic number = ?

We know that the Mass number = protons + neutrons:

Mass number = protons + neutrons

Mass number = 5 + 6:

The wavelength of a yellow light with a frequency of 5.2 x 10¹4 Hz is 6 × 10⁻⁷.

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles. This length is typically defined in wireless systems in meters (m), centimetres (cm), or millimetres (mm) (mm).

When electromagnetic radiation such as radio waves, light waves, or infrared (heat) waves travel through space, they leave behind distinctive patterns. Each wave has a distinct size and shape. Wavelength is the separation between peaks (high points).

By measuring the distance between any two identical locations on adjacent waves, the wavelength can always be found. When a longitudinal wave is present, the distance between one compression and the next is measured to determine the wavelength.

γ = λf

λ = γ / f

= 3 × 10 ⁸ / 5 × 10 ⁴

= 0.6 × 10⁻⁶

λ = 6 × 10 ⁻⁷

Thus, The wavelength of a yellow light with a frequency of 5.2 x 10¹4 Hz is 6 × 10⁻⁷.

The mass number of the third isotope, given the data from the question is 34

The mass number of the third isotope can be obtained as illustrated below:

Relative atomic mass = [(Mass of 1st × Abundance of 1st) / 100] + [(Mass of 2nd × Abundance of 2nd) / 100] + [(Mass of 3rd × Abundance of 3rd) / 100]

32.133 = [(32 × 92.4) / 100] + [(33 × 1.9) / 100] + [(Mass of 3rd × 5.7) / 100]

32.133 = 29.568 + 0.627 + (Mass of 3rd × 0.057)

32.133 = 30.195 + (Mass of 3rd × 0.057)

Collect like term

32.133 - 30.195 = Mass of 3rd × 0.057

1.938 = Mass of 3rd × 0.057

Divide both sides by 0.057

Mass of 3rd = 1.938 / 0.057

Mass of 3rd = 34

Thus, we can conclude that the mass of the 3rd isotope is 34

Using complex-forming processes, complexometric titrations are primarily used to identify metal ions. Despite the fact that a variety of complexing agents can be utilized for this purpose, in actuality, the titrants are virtually always compounds with iminodiacetic acid functional groups. Titration is done in a solution with a pH of 10 (with an ammonium buffer added to promote the complexation of the [tex]Ca^{2+}[/tex]   and [tex]Mg^{2+}[/tex] ions).

Since eriochrome black T forms deep red-wine-colored complexes with just a very small portion of the [tex]Mg^{2+}[/tex] ions, it is employed as the indication to show the end point.

Two monosaccharides are bonded together by a condensation reaction in which glycoside bonds form between the monosaccharides and release the water molecule. In a specific, A reaction, fructose, and glucose molecules combine to generate sucrose (disaccharide).

In the case of the B reaction, two distinct amino acids (monomers) combine to generate a third molecule, a dipeptide; the bond formed between these two molecules is known as a peptide bond (amine group of first amino and cool group of second amino acid). This reaction is also condensation and results in the formation of water molecules. The fact that both create water molecules and dimers from two monomers is shared in this region.

Monosaccharides (from Greek monos: single, saccharin: sugar) are the most fundamental molecules (monomers) from which all carbohydrates are formed.
