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.

Is Acetaminophen ionic, molecular or organic compound

sergejj [24]

Answer:

Organic compound

Explanation:

Acetominophen's molecular formula is C8H9NO2. Right from the formula you can also see that the compound has C (carbon) in it, therefore making it an organic compound (in which the definition is that the compound contains carbon in it).

Please Explain. Why does salt water boil at a lower temperature than tap water?

nexus9112 [7]

We observe that heat capacity of salted water we will find that it is less than pure water. We now that it takes less energy to increase the temperature of the salt water 1°C than pure water. Which means that the salted water heats up faster and eventually reaches to its boiling point first.

What is the percent composition of carbon in heptane c7h16

Gnom [1K]

Answer: the percent composition of carbon in heptane is 83.9%

Explanation:

<u>1) Atomic masses of the atoms:</u>

C: 12.01 g/mol

H: 1.008 g/mol

<u>2) Molar mass of heptane:</u>

C₇H₁₆: 7 × 12.01 g/mol + 16×1.008 g/mol = 100.2 g/mol

<u>3) Mass of carbon in one mole of heptane:</u>

C₇: 7 × 12.01 g/mol = 84.07 g/mol

<u>3) Percent composition of carbon:</u>

% = (mass in grams of C) / (mass in grams of C₇H₁₆) × 100 =

= (84.07 g/ 100.2 g) × 100 = 83.9% ← answer

If the visible light spectrum is from 400 to 700 nm, would light with an energy of 2.79 x 10^-19 J be visible with the naked eye

sladkih [1.3K]

Answer:

713 nm. It is not visible with the naked eye.

Explanation:

Step 1: Given data

Energy of light (E): 2.79 × 10⁻¹⁹ J

Planck's constant (h): 6.63 × 10⁻³⁴ J.s

Speed of light (c): 3.00 × 10⁸ m/s

Wavelength (λ): ?

Step 2: Calculate the wavelength of the light

We will use the Planck-Einstein equation.

E = h × c / λ

λ = h × c / E

λ = 6.63 × 10⁻³⁴ J.s × 3.00 × 10⁸ m/s / 2.79 × 10⁻¹⁹ J

λ = 7.13 × 10⁻⁷ m

Step 3: Convert "λ" to nm

We will use the relationship 1 m = 10⁹ nm.

7.13 × 10⁻⁷ m × (10⁹ nm/1 m) = 713 nm

This light is not in the 400-700 nm interval so it is not visible with the naked eye.
