Answer:

2.86 × 10²⁴ atoms of gold

Explanation:

Given data:

Number of moles of gold = 4.75 mol

Number of atoms = ?

Solution:

The given problem will solve by using 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.

One moles of substance =  6.022 × 10²³ atoms

4.75 moles of gold = 4.75 × 6.022 × 10²³ atoms of gold

28.61 × 10²³ atoms of gold

2.86 × 10²⁴ atoms of gold

How many molecules are in 2.50 moles of h2o
aivan3 [116]
To find out how many molecules you have, you need to multiply the number of moles with Avogadros constant: 2.50 * 6.022 * 10²³ = 1.5055 * 10^24.

For the reaction 2H2O > 2H2 + O2 what is the total number of moles of O2 produced from the complete decomposition of 8 moles
LekaFEV [45]

Answer: Option C) 4 moles

Explanation:

The reaction below shows the decomposition of 2 moles of water to yeild 2 moles of hydrogen and 1 mole of oxygen respectively.

2H2O(l) --> 2H2(g) + O2 (g)

So, if 2 moles of H2O produce 1 mole of O2

8 moles of H2O will produce Z mole of O2

To get the value of Z, cross multiply

2 x Z = 1 x 8

2Z = 8

Z = 8/2

Z = 4

Thus, 4 moles of O2 is produced from the complete decomposition of 8 moles H2O .

Why do some elements form double and triple bonds during bonding
jekas [21]

Explanation:

Elements need a total of eight electrons to gain stability and look like a noble gas. So, they sometimes need sharing of two, four or even six electrons to complete their octate. So, they form double and triple covalent bonds. One more  the reason is the  interaction between the p orbitals of the combining atoms. for example  A double bond, as in ethene H2C=CH2, arises from one combination of the s orbitals and one combination of the p_y orbitals.
