In some chemical reactions, electrons are transferred from one substance to another, but there is no net gain or loss of electro

ns during the reaction. These reactions involve the oxidation, or loss of electrons, of one substance, and the reduction, or gain of electrons, of another. This type of reaction is called a redox reaction. In neutral atoms, such as A and X, the number of protons equals the number of electrons. When atom A loses an electron, the positive charge of the nucleus becomes greater than the negative charge of the electrons, and the resulting ion has a net positive charge, forming a cation. In a reaction, the electron must be taken up by another atom, X , which results in more electrons than protons and a net negative charge on the atom, forming an anion. Mnemonic devices can help in remembering the definitions of oxidation and reduction. Two common mnemonic devices are LEO (Losing Electrons: Oxidation) says GER (Gaining Electrons: Reduction), and OIL (Oxidation Is Losing) RIG (Reduction Is Gaining). Identify the equations that show the oxidation of neutral atom A and the reduction of neutral a

Answer and Explanation:

The equation that depicts oxidation of neutral atom A is  shown below:

\rightarrow A^+ + e^-

This is because one species is losing electrons due to oxidation. The species possesses positively charged after losing electrons, the magnitude of which is proportional to the number of electrons lost.

The net charge will be equivalent on both sides of the equation, too.

Therefore all other options are not correct

The equation that depicts the decline of neutral atom X is

X + e^-  \rightarrow  X^-

It is how a cell gains electrons by reduction. The species obtains a negative charge upon possessing electrons, whose magnitude is equivalent to the amount of electrons gained.

The net charge will be equivalent on both sides of the equation, too.

Therefore all other options are not correct

A chemist heats 100.0 g of FeSO4 x 7H2O in a crucible to drive off the water. If all the water is driven off, what is the mass o
Ierofanga [76]
FeSO₄*7H₂O(s) = FeSO₄(s) + 7H₂O(g)

M(FeSO₄*7H₂O)=278.0 g/mol
M(FeSO₄)=151.9 g/mol

m(FeSO₄*7H₂O)/M(FeSO₄*7H₂O)=m(FeSO₄)/M(FeSO₄)

m(FeSO₄)=M(FeSO₄)m(FeSO₄*7H₂O)/M(FeSO₄*7H₂O)

m(FeSO₄)=151.9*100.0/278.0=54.6 g

m(FeSO₄)=54.6 g

If it takes three "breaths" to blow up a balloon to 1.2 l, and each breath supplies the balloon with 0.060 moles of exhaled air,
vesna_86 [32]
<span>It takes 3 breaths to get to 1.2 l. One breath is then (1.2 l) / 3 breaths = .4l/breath. To get to 3.0 l we need the difference from 1.2 l. 3.0-1.2 = 1.8 l. Divide the difference by liters/breath (.4) to get how many needed breaths. (1.8 l)/(.4 l/breath) = 4.5 breaths to get the balloon to 3.0 l. In total there were 3 breaths+ 4.5 breaths = 7.5breaths to get to 3.0 l. To find the total moles multiply 7.5breaths by .060 moles/breath 7.5 breaths*.060moles/breath = .45moles</span>

If 4.9 kg of CO2 are produced during a combustion reaction, how many molecules of CO2 would be produced?
solmaris [256]

Answer:

6.7 x 10²⁶molecules

Explanation:

Given parameters

Mass of CO₂  = 4.9kg  = 4900g

Unknown:

Number of molecules  = ?

Solution:

To find the number of molecules, we need to find the number of moles first.

 Number of moles  = \frac{mass}{molar mass}

          Molar mass of CO₂  = 12 + 2(16)  = 44g/mol

   Number of moles  = \frac{4900}{44}  = 111.36mole

A mole of substance is the quantity of substance that contains the avogadro's number of particles.

       1 mole  = 6.02 x 10²³molecules

     111.36 moles  =   111.36 x 6.02 x 10²³molecules   = 6.7 x 10²⁶molecules
