Answer:
7.52 x 10²³ molecules N
Explanation:
multiply 1.25 mol of N2 by Avogadro's Number
16 g/ml
<h3>Further explanation</h3>
Given
mass = 32.40 g
volume = 2.0mL
Required
Density
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
ρ = density
m = mass
v = volume
Input the value :
ρ = 32.40 g / 2.0 ml
ρ = 16.2 g/ml
Rules for division: The least number of significant figures in the problem determines the number of significant figures in the answer.
32.40 = 4 sig.fig
2.0 = 2 sig fig
The answer must be 2 sig fig
So the answer = 16 g/ml
Answer:
Noble gases are the least reactive of all elements
Explanation:
because they have eight valence electrons, which fill their outer energy level
Hydrochloric Acid would best be described as an Arrhenius and BrØnsted-Lowrey acid.
<h3>
Is Hydrochloric Acid considered a
Brønsted-Lowry acid?</h3>
Hydrochloric Acid HCl(g) is the proton donor and therefore a Brønsted-Lowry acid.
<h3>
Is Hydrochloric Acid considered an Arrhenius
acid?</h3>
According to Arrhenius theory, hydrochloric acid is an acid which gives hydrogen ions in water but according to Bronsted-Lowry theory, hydrochloric acid is an acid because it donates a proton to the water molecule.
<h3>Is
Hydrochloric Acid considered a Lewis acid?</h3>
Hydrochloric acid (HCl) cannot be classified as a Lewis acid since it cannot accept an electron pair.
Thus, hydrochloric Acid would best be described as an Arrhenius and BrØnsted-Lowrey acid.
