Which quantities are conserved in all oxidation-reduction reactions?

Chemistry
1 answer:
Simora [160]3 years ago
3 0

Answer:

Mass and charge is conserved

Explanation:

According to the law of conservation of mass, matter is neither created or destroyed. With the exception of nuclear reactions where mass is converted to energy thereby leading to an apparent loss in mass, this law applies to chemical reactions.

A redox reaction is a type of chemical reaction which involves a transfer of electrons. In a redox reaction, the mass of reactant particles is conserved. Also, as electrons are transferred between atoms, one donates and the other accepts. The charge of atoms depends on this gain or loss of electrons. A gain of electrons reduced the charge of an atom whereas a loss of electrons increases the charge. This two processes occur concurrently, therefore, charge is also conserved.

Whic of the following are causes of cataracts select all that apply
Dvinal [7]

Answer:

1.  Previous Eye Surgery .

Explanation:  

1. Your medical history can also affect your vulnerability to cataracts. For instance, a previous eye surgery can cause secondary cataracts. Other conditions including diabetes and excessive use of steroids accelerate the chances of cataracts once a person has already undergone previous eye surgeries.

A molecule has the empirical formula C4H6O. If its molecular weight is determined to be about 212 g/mol, what is the most likely
krok68 [10]

Answer:

The molecular formula is C12H18O3

Explanation:

Step 1: Data given

The empirical formula is C4H6O

Molecular weight is 212 g/mol

atomic mass of C = 12 g/mol

atomic mass of H = 1 g/mol

atomic mass of O = 16 g/mol

Step 2: Calculate the molar mass of the empirical formula

Molar mass = 4* 12 + 6*1 +16

Molar mass = 70 g/mol

Step 3: Calculate the molecular formula

We have to multiply the empirical formula by n

n = the molecular weight of the empirical formula / the molecular weight of the molecular formula

n = 70 /212 ≈ 3

We have to multiply the empirical formula by 3

3*(C4H6O- = C12H18O3

The molecular formula is C12H18O3

How many grams of sulfur must be burned to give 100.0 g of So2
andriy [413]

Answer:

50 g of S are needed

Explanation:

To star this, we begin from the reaction:

S(s) + O₂ (g) →  SO₂ (g)

If we burn 1 mol of sulfur with 1 mol of oxygen, we can produce 1 mol of sulfur dioxide. In conclussion, ratio is 1:1.

According to stoichiometry, we can determine the moles of sulfur dioxide produced.

100 g. 1mol / 64.06g = 1.56 moles

This 1.56 moles were orginated by the same amount of S, according to stoichiometry.

Let's convert the moles to mass

1.56 mol . 32.06g / mol = 50 g
