(a) Is a weak Brønsted-Lowry base necessarily a weak Lewis base? Explain with an example.
anyanavicka [17]

Yes, all Bronsted-Lowry bases are Lewis bases, however no longer all Lewis bases are Bronsted-Lowry bases.

<h3>What is a susceptible Brønsted-Lowry bases?</h3>

A susceptible Brønsted-Lowry base indicates very little tendency to acquire a proton.

Weak Brønsted-Lowry bases consist of H2O, Cl- and NO3-. For example, the chloride ion is a vulnerable Brønsted-Lowry base:

<h3>What is the distinction between a Brønsted-Lowry base and a Lewis base?</h3>

Whereas the Brønsted-Lowry and the Arrhenius classifications are primarily based on switch of protons, Lewis acidity and basicity are primarily based on the sharing of an electron pair. Lewis acids can be given an electron pair, whilst Lewis bases can donate an electron pair.

Why would a scientist method of data collection change based on where they conduct their experiment?
serious [3.7K]

Answer: scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis.

Explanation:

When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.

Consider some unknown compound containing only copper and oxygen. In order to determine the empirical formula, a sample of the c
Lina20 [59]

The number of mole of copper in the sample is 0.008 mole.

Mole is simply defined as the unit of amount in a substance.

The mole of a substance can be obtained by dividing the mass of the subtance by its molar mass i.e

Mole = mass / molar mass

With the above information, we can obtain the mole of copper in the compound as follow:

Mass of copper = 0.5066 g

Molar mass of copper = 63.5 g/mol

<h3>Mole of copper =? </h3>

Mole = mass / molar mass

Mole of copper = 0.5066 / 63.5

<h3>Mole of copper = 0.008 mole </h3>

Therefore, 0.008 mole of copper was initially present in the compound.

Similarities of ancient and modern philosophy​
quester [9]
A big difference is that for the Greeks philosophy was almost a fresh start. For us, doing philosophy cannot avoid taking into consideration what the great thinkers of the past have thought (or how they have thought).

_______ is the amount of heat necessary to raise the temperature of 1 gram of a substance by 1 degree Kelvin. A. A calorie B. En
Maksim231197 [3]
<h2>The required option d) "specific heat" is correct.</h2>

Explanation:

  • To raise the temperature of any substance or material of certain mass to respective temperature it requires some amount of heat.
  • Specific heat is the amount of heat necessary to raise the temperature of the substance of 1 gram to 1 Kelvin.
  • It is the amount of heat which is required to raise the temperature per unit mass to per unit temperature.
  • Thus, the required "option d) specific heat" is correct.
