Answer:
the correct answer is B
Explanation:
Subduction: they present if or if two Convergent edges or subduction zones (destructive edges). Where two plates collide, due to having movements with opposite directions, the denser one sinks below the less dense one along what is known as the subduction zone; the subducting plate goes into the mantle, heating up and partially melting generating magma that rises to the surface. A subduction zone is characterized by deformation, volcanism, mountain formation, metamorphism, seismic activity, and significant mineral deposits.
This phenomenon occurs between oceanic plates or between a continental and an oceanic plate, since when there is a difference in density they subduct.
In the event that the edges of two continental plates collide, it would be OBDUCTION, which is another phenomenon other than subduction. mantle does not produce the correct subduction process, as the movement must be absorbed in some way, this is carried out by vertically deforming both plates, which are joined by a suture area, forming an inner mountainous belt and Suffering, in addition, numerous earthquakes. This process is very important, since it is the one that has given rise to the highest mountain ranges on Earth and is a very active process at present (Ex: Los Alpes, Los Montes Urales and Montes Himalaya).
Litmus paper is an indicator that changes color to identify the acidity or basicity of a certain substance. This changes color from blue to red for acids. Since given the same concentration of the compounds, the number of H⁺ in H₂SO₄ is approximately twice that of HCl.
Therefore, fewer drops of H₂SO₄ will be required in order to change the color of the litmus paper.
The given question is an incomplete question, the complete question is given below.
Use this equation to answer the questions that follow.
5 moles of oxygen gas are present. How many moles of 
will be produced with this amount of oxygen gas?
Answer : The moles of produced will be 3.33 moles.
Explanation : Given,
Moles of oxygen gas = 5 moles
Now we have to calculate the moles of .
The given balanced chemical equation is:
From the balanced chemical equation we conclude that,
As, 3 moles of 
gas react to produces 2 moles of gas
So, 5 moles of gas react to produces 
moles of gas
Therefore, the moles of produced will be 3.33 moles.
<h3>Answer:</h3>
H₂O
Explanation:
According to Arrhenius Concept of Acid and Base, "Acid is any specie which when dissolved in water ionizes to produce H⁺ ions".
Examples:
HCl → H⁺ + Cl⁻
H₂SO₄ → 2 H⁺ + SO₄²⁻
While, "Bases are those species which when dissolved in water produces Hydroxyl Ions (OH⁻)".
Examples:
NaOH → Na⁺ + OH⁻
Mg(OH)₂ → Mg²⁺ + 2 OH⁻
Given Options:
CH₃OH:
Methanol when dissolved in water does not dissociate as follow,
CH₃OH → H₃C⁺ + OH⁻
Hence, it does not behave as Arrhenius Base.
CH₃COOH:
Acetic acid when dissolved in water produces H⁺ ions and Acetate ions i.e.
CH₃COOH → CH₃COO⁻ + H⁺
Therefore, it can act as Arrhenius Acid instead of Arrhenius Base.
H₂O:
Water when dissolved in water dissociates as,
H₂O → H⁺ + OH⁻
As it is producing both H⁺ and OH⁻ ions therefore, it can act as both Arrhenius Base and Arrhenius Acid.
H₂NNH₂:
Hydrazine when dissolved in water can neither produce OH⁻ ions nor H⁺ ions hence, it is neither Arrhenius Base nor Arrhenius Acid,
According to the law of conservation of mass, what is the same on both sides of a balanced chemical equation?
A. the volume of the substances
B. the subscripts
C. the total mass of atoms
D. the coefficients
Answer:
A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.
Explanation:
Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. ... Use coefficients of products and reactants to balance the number of atoms of an element on both sides of a chemical equation.
Consider the balanced equation for the combustion of methane.
CH
4
+
2O
2
→
CO
2
+
2H
2
O
All balanced chemical equations must have the same number of each type of atom on both sides of the arrow.
In this equation, we have 1
C
atom, 4
H
atoms, and 4
O
atoms on each side of the arrow.
The number of atoms does not change, so the total mass of all the atoms is the same before and after the reaction. Mass is conserved.
Here is a video that discusses the importance of balancing a chemical equation.
