what did we discover with this experiment​

Yes, an electron cause an electromagnetic wave to vibrate.

One of the waves is propagated by simultaneous periodic variations of electric and magnetic field intensity and that includes radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Electromagnetic waves are produced when something vibrates—an electric charge that moves back and forth.

When an electric charge vibrates, the electric field around it changes. Because the electric charge is in motion, it also has a magnetic field around it.

This magnetic field also changes as the charge vibrates.

Therefore, an electron causes an electromagnetic wave to vibrate.

Answer:

atom

Explanation:

The smallest representative particle of an element is an atom.

Atoms are the fundamental building blocks of matter and the smallest unit of an element that retains the chemical properties of that element. Each atom consists of a nucleus at the center, composed of positively charged protons and neutral neutrons, surrounded by a cloud of negatively charged electrons.

Atoms combine to form molecules or ions through chemical reactions, but they themselves represent the basic structure and identity of an element. Each element has a unique number of protons in its nucleus, known as its atomic number, which determines its position on the periodic table and its distinct chemical properties.

The question requires us to complete the sentences regarding characteristics and properties of lipids.

First, we need to keep in mind what are lipids: these essential molecules to cell's membranes are typically made of a glycerol backbone, fatty acid "tails" (the hydrofobic part) and and a phosphate group (a hydrophilic part). The term "lipids" is commonly used as a synonym for "fats", which it isn't completely wrong as they share many properties (for example, lipids don't mix with water).

As they are organic molecules, all lipids have carbon, oxygen and hydrogen in their structure, while some of them can contain other elements (such as phosphorus for the phospate group and nitrogen).

Considering the information above, we can complete the sentences as:

1. "Lipids is a general term describing organic molecules that are insoluble in water".

2. "All lipids are made of carbon, hydrogen and oxygen, while some lipids contain other elements..."

Explanation:

Sacrificial protection is a corrosion protection method in which a more electrochemically active metal is electrically attached to a less active metal. The highly active metal donates electrons to replace those which may have been lost during oxidation of the protected metal.

Electroplating is a general name for processes that create a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current. The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution of a salt of the metal to be coated; and the anode (positive electrode) is usually either a block of that metal, or of some inert conductive material. The current is provided by an external power supply.

When you mix equal volumes of 1 M CH3COOH and 1 M NaOH, the resulting solution is not a buffer solution.

This is because a buffer solution requires a weak acid and its conjugate base or a weak base and its conjugate acid. The reaction between acetic acid (CH3COOH) and sodium hydroxide (NaOH) is a neutralization reaction.

The reaction produces sodium acetate (NaCH3COO) and water (H2O).CH3COOH + NaOH → NaCH3COO + H2OAcetic acid is a weak acid, and sodium hydroxide is a strong base. The reaction between a strong base and a weak acid produces a salt and water. The resulting solution is not a buffer solution.

Hence, the correct option is option (B). Notably, a buffer solution is a solution that resists changes in pH when small amounts of acid or base are added to it. A buffer solution contains a weak acid and its conjugate base or a weak base and its conjugate acid.

When a strong acid or strong base is added to a buffer solution, it reacts with the weak acid or weak base in the buffer solution, forming the conjugate base or conjugate acid, respectively. This helps to maintain the pH of the buffer solution.

An amino acid chain is also known as a monomer ultimately folds into a three-dimensional shape.

An amino acid chain, also known as a monomer, is the building block of proteins. Proteins are made up of one or more amino acid chains that are linked together. These chains ultimately fold into a three-dimensional shape, which determines the protein's function. The specific sequence of amino acids in a chain, as well as the way the chain folds, are determined by the genetic code. The folding process is influenced by various factors such as temperature, pH, and the presence of other molecules. The three-dimensional shape of a protein is crucial for its function, as it determines how the protein interacts with other molecules in the cell.

The number of molecules in 10.0 gram of NaOH is 15 * 10²².

To solve this question, we need to understand some terms of mole concept,

Mole - It is the amount of substance containing same number of molecules or atoms as there are atoms in 12 gram of carbon-12 isotope.

Molecules - It is group of atoms bonded together, representing the smallest fundamental unit of a chemical compound taking part in chemical reaction.

Molecular weight - The sum of atomic masses of all atoms in molecules.

Avogadro number - It is the number of atoms, ions, electrons, molecules in one mole of substance. It is represented as NA.

NA = 6.0 * 10²³ (approx)

To calculate the number of molecules, we apply the formulae,

no. of molecules = moles * NA

moles = weight / molecular weight

moles = 10.0 / 40

          = 0.25

Substituting this value to calculate number of molecules,

no. of molecules = 0.25 * 6.0 * 10²³

                            = 15 * 10²²

Therefore the number of molecules of in 10.0 g of NaOH is 15 * 10²².

The heat given off in the reaction is 4.62 kJ. This corresponds to the first option in the list of choices.

The given problem involves calculating the amount of heat released in the reaction between 40.0 mL of 1.00 M H2SO4 and 80.0 mL of 1.00 M NaOH at 20.00°C. The temperature of the solution increased to 29.20°C, and the mass of the solution is 120.0 g. The specific heat of the calorimeter and solution is 4.184 J/g•°C. To calculate the heat released in the reaction, we can use the formula q = m C_p Delta T, where q is the heat released, m is the mass of the solution, C_p is the specific heat of the solution and calorimeter, and Delta T is the change in temperature. In this case, we have the values of m, C_p, and Delta T, so we can substitute them into the formula and solve for q.

q = m C_p Delta T
q = 120.0 g x 4.184 J/g•°C x (29.20°C - 20.00°C)
q = 38.5 kJ

We will first use the given formula q = mcΔT to calculate the heat released in the reaction. We have the mass (m) of the solution as 120.0 g, the specific heat capacity (C) as 4.184 J/g°C, and the change in temperature (ΔT) as 29.20°C - 20.00°C = 9.20°C. Using these values, we get q = (120.0 g) * (4.184 J/g°C) * (9.20°C). Upon calculating, we find that q = 4620.96 J, which is equivalent to 4.62 kJ.

Explanation:

the passage describing a neutral atom of nitrogen-14 (N-14) is as follows:

Its nucleus comprises seven protons.

Its nucleus of it has seven neutrons.

Around the nucleus, there are seven electrons arranged in orbits.

Its protons make up its atomic number.

Protons and neutrons together make up their atomic mass.

What is nitrogen-14?

It is demonstrated that nitrogen-14 NMR spectra with spin I = 1 can be detected indirectly in powders spinning at the magic angle (MAS). The approach is based on the transmission of coherence to single- or double-quantum transitions of nitrogen-14 nuclei from a nearby nucleus with S = 1/2, such as carbon-13. Second-order quadrupole–dipole cross terms, also referred to as residual dipolar splittings, are responsible for coherence transfer. The second-order quadrupolar interactions of nitrogen-14 are shown to be responsible for the powder patterns in the two-dimensional NMR spectra. The nitrogen-14 quadrupolar coupling constant, CQ, and asymmetry parameter, Q, are obtained through spectra analysis. These variables may be connected to the solids' structure that contains nitrogen.
