Two quantities in the ideal gas equation that are directly proportional are Pressure and Temperature
In ideal gas law, PV = nRT
A quantity can be directly or indirectly proportional to each other. In case of directly proportional, if one quantity increases other would also increases and vice versa. In the case of indirectly proportional, the opposite happens i.e., increase in one quantity would result in decrease of another.
As we can see in the ideal gas law, increase in pressure (P) would increase number of moles (n) and Temperature (T). Similarly, increase in volume (V) would also increase number of moles (n) and Temperature (T).
If the law was rearranged, we can observe that increase in pressure would decrease the volume and vice versa.

describe dehydration synthesis. in your answer, use starch synthesis as an example. be sure your answer includes the roles of starch, glucose, polymers, monomers, water, and covalent bonds in the process.
The chemical process known as dehydration synthesis, also known as a condensation reaction, involves the covalent bonding of two molecules to create a new molecule while simultaneously releasing a water molecule.
Complex carbohydrates, proteins, DNA, and RNA are just a few of the molecules that are formed via dehydration synthesis processes and are crucial to human health.
Dehydration synthesis forms covalent bonds between sugar molecules. The hydroxyl (-OH) group from one reactant joins with the hydrogen atom from the other to generate water throughout the reaction, while the leftover oxygen forms a glycosidic bond that binds the two molecules together. Repeated dehydration synthesis of individual glucose molecules (monomers) can result in the formation of a polymer, which is a long chain or branched chain structure.
Dehydration synthesis processes, in which one monomer establishes a covalent connection to another monomer (or expanding chain of monomers), release a water molecule in the process, are frequently used to create large biological molecules. Dehydration stands for the loss of the water molecule and synthesis for the development of a new bond, making it easy to recall what occurs.
The methods through which monomers can combine to produce polymers are quite diverse. For instance, starch, cellulose, and glycogen are all made up of glucose monomers. These three polysaccharides, which are categorized as carbohydrates, were created as a result of several glucose monomer-to-glucose dehydration synthesis processes. These three distinct polysaccharides, however, have varied characteristics and functions because of the way that glucose monomers combine, particularly the positions of the covalent connections between linked monomers and the orientation (stereochemistry) of the covalent bonds.

What do substances that conduct electricity once they are dissolved have in common?
Answer:
They are ionic compounds.
Explanation:
Ionic compounds are made from a metal element and a nonmetal element. Ionic compounds have bonds that are the transfer of their electrons. They consist of a positively charged and negative charged ion.
When ionic compounds are dissolved in water, this means that the bonds from the compound are broken and now they will be bonding with the water molecules in water.
The electricity in the solution happens when these ions are moving around freely in water.
acid flux is designed to be used on nonelectrical metal joints such as radiators and must be removed after the soldering process so that the joint does not corrode.
It is true that acid flux is used on non-electrical metal joints, such as radiators but need to be removed so that the joint does not corrode after soldering.
Acid flux must be removed after soldering in order to prevent corrosion of the junction and is intended to be used on non-electrical metal connections, such as radiators.
A substance called acid soldering flux is applied to the joint between two pieces of metal to clean and shield it.
Fluxing achieves three objectives: it lessens oxidation, enhances electrical contact, and promotes uniform solder flow. Flux helps eliminate oxidation from the electrical lead you are soldering and blocks airflow to the lead, preventing additional oxidation.
Water-soluble flux is another name for organic acid flux. These organic acids, including citric, lactic, and stearic acid, are used to make this sort of flux. After that, organic solvents like alcohol or isopropyl are added to the acids. Metal oxides can be removed more successfully using organic acid flux.
As a result, it is accurate to say that acid flux must be removed after soldering in order to prevent corrosion of the joint on non-electrical metal components like radiators.

In accordance with Hess's law, the total enthalpy of the reaction in question would be -200 kJ.
Hess's law (also known as Hess's law of constant heat summation) states that regardless of the multiple steps or stages of a reaction, the total enthalpy change for the reaction is the sum of all stages. This means that if the reaction has two steps, their individual changes in enthalpy contribute to the total change in enthalpy for the sum reaction. In this case, one step is exothermic (-658 kJ), and the other is endothermic (458 kJ), but the overall reaction is still exothermic (-658 kJ + 458 kJ = -200 kJ) because the absolute value for enthalpy change in the first reaction is greater than the absolute value for enthalpy change in the second reaction.

One mole of iron _____.
has the same mass as one mole of lead.
cannot be compared to lead because it is magnetic.
has less mass than one mole of lead.
has more mass than one mole of lead.
Answer:
One mole of O2 will have approximately the same mass as one mole of methanol (CH3OH).
Recall that: mole = mass/molar mass
Thus, one mole O2 will have a mass of:
mass = mole x molar mass
= 1 x 32
= 32 g
One mole of CH3OH = mass/molar mass
mass = 1 x 32
= 32 g
Hence, 1 mole of O2 will have the same mass (32 g) as 1 mole of CH3OH
As a reminder, the atomic mass of an atom equals the mass of a mole of this atom.
Just so you know, a mole is defined as a quantity of 6.02x10^{23} things.
We know that the atomic mass of Oxygen is 16 so one mole of O2's mass is 16*2=32g.
So I guess we need to figure out something which a mole of will weight 32 g.
You can pick Ethanol which formula is CH3OH.
C has an atomic mass of 12
H has an atomic mass of 1
O has an atomic mass of 16
So one mole of CH3OH weights 12+(3*1)+16+1=32g which is the same amount.

1-bromo-2-methylpropane undergoes an Sn2 reaction with the methoxide to yield 1-methoxy-2-methylpropane (isobutyl methyl ether) and the bromide ion. Please see the reaction mechanism shown in the attached material.
Alkyl halides are excellent electrophiles because of the polar carbon-halogen bond that provides both the electrophilic carbon atom and the excellent leaving group in the form of the halide ion. When attacked by a nucleophile (such as the methoxide ion), they undergo an Sn2 reaction (bimolecular nucleophilic substitution).
The reaction mechanism of an Sn2 reaction consists of a single phase: the simultaneous attack by the nucleophile and the abstraction of the leaving group. This process implies that there is a transition state that contains a quasi-pentavalent carbon atom, as one bond is forming and the other is being dissolved.
