Answer:

The correct alternative is "Option a".

Explanation:

Oxidation has become a mechanism whereby the physicochemical properties transform attributed to the formation of O₂.

  • The connection involving magnesium as well as O₂ requires the oxidation of the component named magnesium.
  • Even before exposed to the air, silicon is oxidized as well as generates silicon dioxide.

Other possibilities are not connected to the scenario in question. So Choice A is the best option.

Using two different instruments I measured the length of my foot to be 27 centimeters and 27.00 centimeters. Explain the differe
Sophie [7]

Answer:

As you used two diferent instruments, one is more sensitive than the other.

Explanation:

The sensitivity of an instrument is the minimum amount of magnitude that can be  differentiate a measurement system.

In method A, you got 27 cm, so if in method B, you got 27.00, method B is more sensitive. It's like saying that one system measures more than the other

When the following equation is balanced, what is the coefficient for NaNO3?
notka56 [123]

The coefficient for NaNO₃ = 6

<h3>Further explanation </h3>

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:  

• 1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.  

• 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product  

• 3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

Reaction

AI(NO₃)₃ +Na₂SO₄ → Al₂(SO₄) + NaNO₃

give coefficient

aAI(NO₃)₃ +bNa₂SO₄ → Al₂(SO₄)₃ +c NaNO₃

Al, left=a, right=2⇒a=2

N, left=3a, right=c⇒3a=c⇒3.2=c⇒c=6

Na, left=2b, right=c⇒2b=c⇒2b=6⇒b=3

The equation becomes :

2AI(NO₃)₃ +3Na₂SO₄ → Al₂(SO₄)₃ +6NaNO₃
