a quantity of zinc reacts with sulfuric acid and produces 0.10g of hydrogen. how many particles of zinc are required socratic.or

alekssr [168]

Answer:

grams of zinc required = 3.24 g

Particles of zinc required = $2.99\times 10^{22}$

Explanation:

Given that:-

Mass of hydrogen gas produced = 0.10 g

Calculation of the moles of $H_2$ as:-

Mass = 0.10 g

Molar mass of $H_2$ = 2.016 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{0.10\ g}{2.016\ g/mol}$

$Moles= 0.0496\ mol$

According to the reaction shown below:-

$Zn+H_2SO_4\rightarrow ZnSO_4+H_2$

1 mole of hydrogen gas is produced when 1 mole of zinc reacts

So,

0.0496 mole of hydrogen gas is produced when 0.0496 mole of zinc reacts

Moles of Zinc required = 0.0496 moles

Molar mass of zinc = 65.38 g/mol

mass= Moles*Molar mass = $0.0496\ moles\times 65.38\ g/mol=3.24\ g$

Also, 1 mole of Zinc contains $6.023\times 10^{23}$ particles

0.0496 mole of Zinc contains $0.0496\times 6.023\times 10^{23}$ particles

Particles of zinc required = $2.99\times 10^{22}$

What is the percent s character in an sp^2 hybridized orbital? 25% 33% 50% 67% 75%

Brums [2.3K]

Answer:

The correct option is: B. 33%

Explanation:

Orbital hybridisation refers to the mixing of atomic orbitals of the atoms in order to form new hybrid orbitals. The concept of orbital hybridization is used to explain the structure of a molecule.

The sp² hybrid orbitals are formed by the hybridization of one 2s orbital and two 2p orbitals. <u>The three sp² hybrid orbitals formed have 33% s character and 67% p character.</u>

Answer:

hope this helps have a amazing day! :)

Explanation:

Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions.
