Relate the strength of a weak acid to the strength of a conjugate base.

Chemistry
1 answer:
Elenna [48]3 years ago
4 0

Answer:

There is a relationship between the strength of an acid (or base) and the strength of its conjugate base (or conjugate acid): The stronger the acid, the weaker its conjugate base.  The weaker the acid, the stronger its conjugate base.  The stronger the base, the weaker its conjugate acid.

explanation

The strength of an acid and a base is determined by how completely they dissociate in water. Strong acids (like stomach acid) break down or dissociate in water. Weak acids maintains their protons in water.

Explain the working principle of a clinical thermometer ​
bagirrra123 [75]

Answer:

A clinical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own.

Answer:

  • 75.5 g O₂ (g) can be produced from 42.6 g of H₂O (g)

Explanation:

<u>1) Balanced chemical equation (given):</u>

  • 2H₂O(g) → 2H₂(g) + O₂(g)

<u>2) Mole ratios:</u>

  • 2 moles H₂O(g) : 2 moles H₂(g) : 2 moles O₂(g)

<u>3) Calculate the number of moles of reactant (H₂0):</u>

  • number of moles = mass in grams / molar mass

  • molar mass of water: 18.015 g/mol

  • mass in grams of water: 42.6 g

  • number of moles = 42.6 g / 18.05 g/mol = 2.36 moles H₂O

<u>4) Set a proportion using the mole ratio  O₂ to H₂O and the actual number of moles of H₂O:</u>

  • 2 moles O₂ / 2 moles H₂O = x / 2.36 moles H₂O

  • x = 2.36 moles O₂

<u>5) Convert 2.36 moles O₂ to grams:</u>

  • mass in grams = number of moles × molar mass

  • mass = 2.36 moles × 32.00 g/mol = 75.5 g O₂

50 atoms, 15 were isotope A, 30 were isotope B, and 5 were isotope C, which isotope would be the most abundant?
Juliette [100K]

The most abundant isotope among the given Isotopes will be Isotope B

<h3>How to calculate percentage abundance of isotopes ?</h3>

To calculate the percent abundance of each isotope in a sample of an element, we usually divide the number of atoms of a particular isotope by the total number of atoms of all isotopes of that element and then multiply the result by 100.

  • For  Isotope A ;

% Abundance =  15/50 x 100

                        =  30 %

  • For  Isotope B ;

% Abundance =  30/50 x 100

                        =  60 %

  • For  Isotope A ;

% Abundance =  5/50 x 100

                        =  10 %

Hence, The most abundant isotope among the given Isotopes will be Isotope B.
