For the topic of conjugate acids and bases you know that the if you have an acid (sometimes labeled as HA), its conjugate base is HA minus one H⁺ ion (sometimes called a proton).  The conjugate base of HCl is Cl₋, the conjugate base of H₂SO₄ is HSO₄⁻, the conjugate base of CH₃COOH is CH₃COO⁻, and so on.  To find the conjugate acid of a base, you have to reverse that process.  The conjugate acid of HCO₃⁻ is H₂CO₃, the conjugate acid of NH₃ is NH₄⁺, the conjugate acid of PO₄³⁻ is HPO₄²⁻, and so on.  

examples:
HCl+H₂O⇒H₃O⁺+Cl⁻
acid=HCl, base=H₂O, conjugate base=Cl⁻, and conjugate acid=H₃O⁺

NH₃+H₂O⇒NH₄⁺+OH⁻
acid=H₂O, base=NH₃, conjugate base=OH⁻, and conjugate acid=NH₄⁺

I hope this helps.  Let me know if anything is unclear or you want me to explain anything further.

2. How is the layer of iridium used to tell the relative age of different rock strata and fossils?
Fantom [35]

Answer and Explanation:deposition has been occurring on earth for a very long time. as time goes by, more deposits form layers on the earth, including the remains of animals and plants that would later become fossils, burying the previous deposits in another layer of newer deposits. therefore it follows that layers which are found deeper are older than those found in layers near the surface....

The reaction of a Lewis acid with a Lewis base would most likely be accompanied by an increase in which item?
Leokris [45]

The correct option is COVALENT BONDS.

A Lewis acid is defined as a substance which accept a pair of electron while a Lewis base refers to a substance that donate an unshared pair of electrons to another chemical specie with which it shared the donated pair of electrons.

Lewis acid and Lewis base react together to form salt and water. This type of reaction is called neutralization reaction. The neutralization reaction of Lewis acid and Lewis base involves electron pairs transfer, thus, there is an increase in the number of covalent bonds during this reaction.

A cylinder with a movable piston originally has a volume of 2805 mL and is filled with nitrogen to a pressure of 4.00
Sergio039 [100]

This problem is providing the initial volume and pressure of nitrogen in a piston-cylinder system and asks for the final pressure it will have when the volume increases. At the end, the answer turns out to be 2.90 atm.

<h3>Boyle's law</h3>

In chemistry, gas laws are used so as to understand the volume-pressure-temperature-moles behavior in ideal gases and relate different pairs of variables.

In this case, we focus on the Boyle's law as an inversely proportional relationship between both pressure and volume at constant both temperature and moles:

P_1V_1=P_2V_2

Thus, we solve for the final pressure by dividing both sides by V2:

P_2=\frac{P_1V_1}{V_2}

Hence, we plug in both the initial pressure and volume and final volume in order to calculate the final pressure:

P_2=\frac{2805mL*4.00atm}{3864mL}\\ \\P_2=2.90atm
