According to current theory, a major reason for bonding is to gain the stability of the octet formation. In order for an octet (8 parts) formation to be stable, there has to be a bond achieved among the elements which comprise it.

1. mol ratio of Al(NO₃)₃ : Na₂CO₃ = 2 : 3

2. Na₂CO₃ as a limiting reactant

<h3>Further explanation</h3>

Given

Reaction

2 Al(NO₃)₃ + 3 Na₂CO₃ → Al₂(CO₃)₃ + 6 NaNO₃

Required

mol ratio

Limiting reactant

Solution

The reaction coefficient in the chemical equation shows the mole ratio of the components of the compound involved in the reaction (reactants and products)

1. From the equation mol ratio of Al(NO₃)₃ : Na₂CO₃ = 2 : 3

2. mol : coefficient of Al(NO₃)₃ : Na₂CO₃ = 2 mole/2 : 2 mole/3 = 1 : 0.67

Na₂CO₃ as a limiting reactant (smaller)

A canoe displaces 100 L of water. Water weighs 9.8 N/L. What is the buoyant force on the canoe?
Setler79 [48]

Hey there!


The Buoyant force is going to be equal to the weight of the water displaced and it would be like this 100 L(9.8 N/L) = 980 N.

In 1808, John Dalton proposed a series of statements regarding the atom that became known as Dalton's postulates or Dalton's ato
Oduvanchick [21]

Answer:

The all 4 the given statements are part of Dalton's atomic theory.

Explanation:

Dalton's postulates or Dalton's atomic theory:

  • Matter is made up of small particles termed as atom.
  • Atoms are indivisible particle.
  • Atoms of different element have different masses and properties.
  • Atoms of the same element have the identical size, mass, and structure.
  • During chemical reaction, rearrangement of atoms takes place.
  • Atoms of different different combines together to form new compounds in simple whole number ratio.

The electronic transition in a hydrogen atom from n = 7 to n = 2 emits electromagnetic radiation having a longer wavelength than
Tema [17]

Answer: I'll leave the answer rounded to three sig figs.

mark me brainlist

So, you can say that in a hydrogen atom, an electron located on  

n

i

=

2

that absorbs a photon of energy  

4.85

⋅

10

−

19

 

J

can make the jump to  

n

f

=

6

.

Explanation:

The question wants you to determine the energy that the incoming photon must have in order to allow the electron that absorbs it to jump from  

n

i

=

2

to  

n

f

=

6

.

A good starting point here will be to calculate the energy of the photon emitted when the electron falls from  

n

i

=

6

to  

n

f

=

2

by using the Rydberg equation.
