A Lewis acid is an electron-pair acceptor.

Bronsted-Lowry bases are species that can accept a proton.

Arrhenius acid gives H^{+} ions.

<h3>What is acid?</h3>

An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).

A Lewis acid is therefore any substance, such as the H^+ion, that can accept a pair of nonbonding electrons.  In other words, a Lewis acid is an electron-pair acceptor.

Bronsted-Lowry bases are species that can accept a proton due to a high-energy pair of electrons being present.

According to Arrhenius, the acids are the hydrogen-containing compounds which give H^+ ions or protons on dissociation in water and bases are the hydroxide compounds which give OH^- ions on dissociation in water.

How many grams are in 0.90 mol Pd?*
maria [59]

Mass of Pd = 95.78 g which is close the the variant E) 95.89

Explanation:

To calculate the number of moles of palladium (Pd) we use the following formula:

number of moles = mass / atomic weight

mass = number of moles × atomic weight

mass of Pd = 0.90 × 106.42

mass of Pd = 95.78 g

A 0.500 g sample of C7H5N2O6 is burned in a calorimeter containing 600. g of water at 20.0∘C. If the heat capacity of the bomb c
Studentka2010 [4]

Answer:

22.7

Explanation:

First, find the energy released by the mass of the sample. The heat of combustion is the heat per mole of the fuel:

ΔHC=qrxnn

We can rearrange the equation to solve for qrxn, remembering to convert the mass of sample into moles:

qrxn=ΔHrxn×n=−3374 kJ/mol×(0.500 g×1 mol213.125 g)=−7.916 kJ=−7916 J

The heat released by the reaction must be equal to the sum of the heat absorbed by the water and the calorimeter itself:

qrxn=−(qwater+qbomb)

The heat absorbed by the water can be calculated using the specific heat of water:

qwater=mcΔT

The heat absorbed by the calorimeter can be calculated from the heat capacity of the calorimeter:

qbomb=CΔT

Combine both equations into the first equation and substitute the known values, with ΔT=Tfinal−20.0∘C:

−7916 J=−[(4.184 Jg ∘C)(600. g)(Tfinal–20.0∘C)+(420. J∘C)(Tfinal–20.0∘C)]

Distribute the terms of each multiplication and simplify:

−7916 J=−[(2510.4 J∘C×Tfinal)–(2510.4 J∘C×20.0∘C)+(420. J∘C×Tfinal)–(420. J∘C×20.0∘C)]=−[(2510.4 J∘C×Tfinal)–50208 J+(420. J∘C×Tfinal)–8400 J]

Add the like terms and simplify:

−7916 J=−2930.4 J∘C×Tfinal+58608 J

Finally, solve for Tfinal:

−66524 J=−2930.4 J∘C×Tfinal

Tfinal=22.701∘C

The answer should have three significant figures, so round to 22.7∘C.
