all of the other things are made up of atoms, not what atoms themselves are made of.  they are not large, and they make up all matter

An atom is made up of a nucleus and revolving electrons. Inside the nucleus protons and neutrons are located. Thus the components of an atom are protons, electrons and neutrons. Thus, option A is correct.

An atom is the basic unit of every substances. Atoms combine together to form molecules, molecules then forms compounds and so on.

The inner core of an atom is called nucleus which contains positively charged particles namely protons and neutral particles neutrons. There are circular paths of fixed energy surrounding the nucleus.

The circular paths around the nucleus is called orbits through which the electrons are revolving. Electrons are negatively charged particles and they neutralize equal number of positive charges.

A neutral atom have equal number of protons and electrons and this number is called its atomic number. The sum of number of protons and neutrons is called the mass number.

Hence, an atom is made up of protons, electrons, and neutrons and option A is correct.

Increasing the pressure and decreasing the temperature will decrease the partial pressure of carbon dioxide at equilibrium, while adding more MoO(s) and removing some CO(g) will have no effect on the partial pressure of carbon dioxide at equilibrium.

According to Le Chatelier's principle, when a system at equilibrium is subjected to a change in conditions, the system will shift to counteract the change and re-establish equilibrium. In this case, the changes that will affect the partial pressure of carbon dioxide at equilibrium are:
1) Increasing the pressure: If the pressure is increased, the system will shift to the side with fewer moles of gas to reduce the pressure. In this case, the system will shift to the left, decreasing the partial pressure of carbon dioxide at equilibrium.
2) Decreasing the temperature: Since the reaction is endothermic, decreasing the temperature will shift the equilibrium to the left, decreasing the partial pressure of carbon dioxide at equilibrium.
3) Adding more MoO(s): Adding more MoO(s) will not affect the partial pressure of carbon dioxide at equilibrium because it is a solid and does not affect the pressure of the system.
4) Removing some CO(g): Removing some CO(g) will shift the equilibrium to the left to replace the removed CO(g), decreasing the partial pressure of carbon dioxide at equilibrium.

Answer:

The volume will also decrease.

Explanation:

This illustration clearly indicates Boyle's law.

Boyle's law states that the volume of a fixed mass of gas is directly proportional to the absolute temperature, provided the pressure remains constant. Mathematically, it is represented as:

V & T

V = KT

K = V/T

V1/T1 = V2/T2 =... = Vn/Tn

Where:

T1 and T2 are the initial and final temperature respectively, measured in Kelvin.

V1 and V2 are the initial and final volume of the gas respectively.

From the illustration above, the volume is directly proportional to the temperature. This implies that as the temperature increases, the volume will also increase and as the temperature decreases, the volume also will decrease.

The molecular formula of a new protein found in a plant from the Brazilian rainforest that may be a treatment for Crohn's disease with an empirical formula of CH7NO2S3 and a molecular mass of 483 g/mol is C6H14N2O2S3. This is an Empirical formula

CH7NO2S3Molecular mass: 483 g/mol The molecular formula of a protein molecule indicates the actual number of atoms of each element present in one molecule. Thus, to calculate the molecular formula of the given protein, we need to find the actual molecular mass of the protein. To do so, we can find the ratio between the empirical and actual molecular masses as follows

Empirical formula mass = (12.01 × 1) + (1.01 × 7) + (14.01 × 1) + (32.06 × 3)Empirical formula mass = 12.01 + 7.07 + 14.01 + 96.18Empirical formula mass = 129.27 g/mol Actual formula mass/empirical formula mass = nActual formula mass = n × empirical formula mass483 g/mol/129.27 g/mol = n3.7366 = n ≈ 4n = 4Hence, the molecular formula of the protein is 4 times the empirical formula:C4H28N4O8S12Reducing the formula to the simplest whole-number ratio gives the are molecular formula: (C4H28N4O8S12) / 4 = C1H7N1O2S3C1H7N1O2S3 is not the molecular formula of the protein the because it has fractional subscripts. So, we can multiply all the subscripts by 6 to obtain a whole-number are the are ratio:C1H7N1O2S3 × 6 = C6H42N6O12S18Reducing the formula to the simplest whole-number ratio again gives the molecular formula:C6H14N2O2S3Hence, the molecular formula of the protein is C6H14N2O2S3.

The liquid solvent used in chromatography is known as the mobile phase.

In chromatography, the liquid solvent used is known as the mobile phase. The mobile phase is a liquid or a mixture of liquids that carries the sample through the stationary phase. It plays a crucial role in separating the components of a mixture based on their different affinities for the stationary phase.

The choice of solvent in chromatography depends on various factors such as the nature of the sample, the type of chromatography being performed, and the desired separation. Commonly used liquid solvents include water, methanol, ethanol, acetonitrile, and hexane.

For example, in thin-layer chromatography (TLC), a common technique used in chemistry labs, the mobile phase is typically a mixture of a nonpolar solvent (such as hexane) and a polar solvent (such as ethyl acetate or methanol). This combination allows for the separation of different compounds based on their polarity.

The liquid solvent used in chromatography is known as the mobile phase.

The answer provided is "mobile phase," which refers to the liquid solvent used in chromatography.

Chromatography is a technique used to separate and analyze the components of a mixture based on their differential affinities to a stationary phase and a mobile phase.

The mobile phase is the liquid or gas that carries the sample through the stationary phase.

In liquid chromatography, the mobile phase is typically a liquid solvent, such as a mixture of water and organic solvents.

The choice of mobile phase depends on the nature of the sample and the desired separation. Different solvents or solvent mixtures have varying polarities and elution strengths, allowing for selective separation of components.

The mobile phase moves through the stationary phase, which can be a solid adsorbent or a liquid-coated surface.

As the mobile phase passes through the stationary phase, the components of the sample interact differently with the stationary phase based on their chemical properties, resulting in separation.

Overall, the mobile phase plays a crucial role in chromatography by facilitating the movement and separation of sample components, allowing for their identification and analysis.

The fluorescent bulb has a better energy output than the regular bulb.

The main difference between the energy output of a fluorescent bulb and a regular (incandescent) bulb is their efficiency. Fluorescent bulbs are much more energy-efficient than incandescent bulbs because they convert a much higher proportion of the energy they consume into visible light, rather than heat.

Incandescent bulbs work by heating a filament inside the bulb until it glows, emitting light. However, this process is very inefficient, with most of the energy consumed being lost as heat. In contrast, fluorescent bulbs use a small amount of energy to excite a gas inside the bulb, which then emits ultraviolet (UV) light.

Explanation:

For the equilibrium; A + B ⇄C + D

At time = 0 secs, the concentration of products is zero while the concentration of reactants decreases steadily.

As time goes on, the concentration of the reactants continues to decrease while the concentration of products increases.

At equilibrium the concentration of both reactants and products are now the same because the rate of forward reaction is equal to the rate of reverse reaction are now the same.

The correct answer is (b) alpha helices and beta sheets are formed by hydrogen bonds between amino acids that are nearby in the linear amino acid sequence.

In an alpha helix, the amino acids are arranged in a spiral shape, with the N-H group of one amino acid hydrogen bonded to the C=O group of the amino acid four residues further along the chain. This creates a strong, stabilizing force that helps to keep the alpha helix in its shape.

In a beta sheet, the amino acids are arranged in a flat, sheet-like structure, with the N-H group of one amino acid hydrogen bonded to the C=O group of the amino acid four residues further along the chain, but on the opposite strand of the sheet. This creates a strong, stabilizing force that helps to keep the beta sheet in its shape.

In both cases, the hydrogen bonds are between amino acids that are nearby in the linear amino acid sequence. This is because the amino acids in a protein chain are linked together by peptide bonds, which are short chains of carbon and nitrogen atoms.

The N-H group of one amino acid is located directly next to the C=O group of the amino acid that is bonded to it by a peptide bond. This makes it possible for the N-H group to hydrogen bond to the C=O group of the amino acid four residues further along the chain.

The statements that alpha helices and beta sheets are formed by hydrogen bonds between amino acids that are far apart in the linear amino acid sequence, and that an alpha helix is formed by hydrogen bonds between amino acids that are nearby in the linear amino acid sequence, while beta sheets are formed by hydrogen bonds between amino acids further away from each other in the linear amino acid sequence are both incorrect.

Therefore, (b) alpha helices and beta sheets are formed by hydrogen bonds between amino acids that are nearby in the linear amino acid sequence is the correct answer.
