How much mass would a mole of hydrogen molecules contain?
dsp73

Answer:

2.016 g/mol

Explanation:

Avogadro number

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

For H₂:

2.016 g of H₂ = one mole of hydrogen gas = 6.022 × 10²³ molecules of hydrogen

Give the stoichiometric coefficient for oxygen when the following equation is balanced using the lowest, whole-number coefficien
Mademuasel [1]

Answer: 2 \cdot CH_{4} O (l)+3 \cdot O_{2}(g) \rightharpoonup 2 \cdot CO_{2}(g) + 4 \cdot H_{2}O(l)

Explanation:

Let consider that one mole of diatomic oxygen is used. So, the stoichometric can be modelled by using three variables:

x \cdot CH_{4} O (l)+O_{2}(g) \rightharpoonup y \cdot CO_{2}(g) + z \cdot H_{2}O(l)

Where x,y,z are the required variables.

Now, three equations are constructed from the number of elements involved (Carbon, Hydrogen and Oxygen):

Carbon

x=y

Oxygen

x+2=2\cdot y + z

Hydrogen

4\cdot x = 2 \cdot z

The coefficients can be found by solving the abovementioned 3 x 3 Linear System:

x = \frac{2}{3}, y = \frac{2}{3}, z = \frac{4}{3}

The whole-number coefficients are determined by multiplying every coefficient by 3, then:

2 \cdot CH_{4} O (l)+3 \cdot O_{2}(g) \rightharpoonup 2 \cdot CO_{2}(g) + 4 \cdot H_{2}O(l)

Based on the contributions of early scientists, one can conclude that one discovery was ​
Anna11 [10]

Answer:

the discovery of atomic structure.

Explanation:

Rutherford was a famous scientist who gave his theory of atomic structure.

Ernest Rutherford was a great physicist who is well known for his pioneering studies and discoveries about atoms and radioactivity. Rutherford was considered to be the greatest experimentalist after Michael Faraday.

Rutherford's atomic model was one of the greatest discoveries which provided many answers and solutions to the structure of atom and molecules that our earth is surrounded of.

Rutheford discovered that an atom has a tiny mass of positively charged particles in the centre of the atom called nucleus and negatively charged electrons surrounds the nucleus.

Bohr joined Rutherford in his studies and discovered many new facts about the structure of the atom based on the Rutherford's model. Today atomic model is the product of Rutherford atomic structure.
