The ans is C. Hydrogen, deuterium amd tritium are all isotopes of hydrogen. Isotopes only differ in their number of neutrons. Hence, the ans is c
Do you have a picture of the graph?
7.20594 x 10^20
First you must determine how many moles of P3O5 you have. This is done by using the formula
Number of moles (n) = mass in grams of substance (m) /divided by/ Molar mass (M) [this is the sum of the atomic mass of all atoms in the compound]
n = 0.170 / P (31 x 2) + O (16 x 5)
n = 0.170 / 142
n = 0.001197 moles
Then you use avagadros number 6.02 x10^23 this is the number of atoms in one mole of any substance. Since you have 0.001197 moles you multiply the number of moles by avagadros number
0.001197 x (6.02 x 10^23)
= 7.20594 x 10^20 atoms
Answer:
Correct option is B. It shows the ratio of elements in the compound.
Explanation:
Empirical formula is the simplest form of the chemical formula. It shows the simplest ratio of atoms in compounds. It is determined by %age of each element.
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.
