Answer:
CH₃CH₂CH₂OH → CH₃CH=CH₂ + H₂O
Explanation:
La ecuación que representa la reacción del alcohol 1-butílico (también llamado como 1-butanol o n-butanol) con H₂SO₄ como catalizador a altas temperaturas es:
CH₃CH₂CH₂OH → CH₃CH=CH₂ + H₂O
Los productos son agua y buteno.
Answer:
C. H2O (l) --> H2O (g)
Explanation:
Hello,
In this case, we need to remember that processes absorbing energy are those that have positive heat, it means, process that obtain energy from a certain source. In such a way, processes that need energy, in terms of phase chance are fusion, sublimation and evaporation, which are the change from solid to liquid, solid to gas and liquid to gas respectively. Therefore, for the given options, we can see that C. H2O (l) --> H2O (g) accounts for an evaporation process which actually absorbs energy.

Which of these events best fits the box labeled A?
A.destruction of cells
B.appearance of bacteria
C.creation of primitive plants
D.transformation of atmosphere
The rectangle A at the bottom will represent the appearance of bacteria as shown in the attached figure below. Therefore, option (B) is correct.
In biology, the origin of life can be described as the natural process by which life has arisen from non-living matter. The prevailing scientific hypothesis can be described as that the transition from non-living matter to living entities was not a single event.
An evolutionary process that can be involved in the formation of a habitable planet, is the prebiotic synthesis of organic molecules, molecular self-replication autocatalysis, and the emergence of cell membranes.
The study of abiogenesis or the origin of life objectives to determine how pre-life reactions gave origin to live under conditions different from those on Earth today. It uses tools from the fields of biology and chemistry, with recent approaches attempting a synthesis of many sciences.
Therefore, the flow charge will be like living matter → Chemical processes → the appearance of bacteria.

Answer:
New pressure = 42216.66 Pa
Explanation:
Given that,
Initial volume, V₁ = 5 m³
Final pressure, P₁ = 101320 Pa
Final volume, V₂ = 12 m³
We need to find the final pressure of the gas. We know that the relation between pressure and volume is given by :
So, the new pressure is equal to 42216.66 Pa.
(2) decomposition
(3) single replacement
(4) double replacement
The correct answer is (1) Synthesis
Explanation:
In chemistry, synthesis reaction occurs as two or more substance combine and form a single and complex product, due to this, synthesis reaction is also known as a direct combination, because different to decomposition or replacement reactions the final product includes the substances that were combined. For example, water (H2O) is formed through synthesis by mixing two atoms of hydrogen (H2) and one of Oxygen (H) which means the substances combined form a single substance. Thus, the type of reaction described is Synthesis reaction.
Explanation:
Acid rain is caused due to increase in nitrogen oxide and sulfur oxide into the atmosphere.
The amount of these oxides increases into the atmosphere due to increase in pollution.
Therefore, pollution is caused by humans. For example, pollution from sources like vehicles, industries, factories, labs etc leads to increase in the development of harmful gases.
Thus, the statement acid rain is caused by human activity is true.
