In this reaction, ammonia molecules (NH3) act as a base because they
(1) accept hydrogen ions (H+)
(2) accept hydroxide ions (OH-)
(3) donate hydrogen ions (H+)
(4) donate hydroxide ions (OH-)
Answer:
1. accept hydrogen ions (H+)
Explanation:
In the given reaction, NH3 acts as a base because it accepts hydrogen ions (H+) from the acid HCl to form the conjugate acid NH4+. Therefore, the correct answer is 1. accept hydrogen ions (H+).
B. Photovoltaic
C. Hydrophobic
D. Hydroelectric
Answer: Option (D) is the correct answer.
Explanation:
When kinetic energy of falling water is converted to electricity then the generated power is called hydroelectric power.
In a hydroelectric plant, a reservoir is used to store water in a dam. This dam is located on a river. When water is released from this reservoir then it flows through the turbine. As a result, this turbine spins and activates a generator which produces electricity.
Thus, we can conclude that hydroelectric power is generated by converting the kinetic energy of falling water to electricity.
73 Draw a structural formula for the ethanol formed during this reaction.
74 Describe how the catalyst, zymase, speeds up this reaction.
75 Determine the total mass of ethanol produced when 270. grams of glucose reacts completely to form ethanol and 132 grams of carbon dioxide.
Answer:
A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change
Which type of chemical reaction does this equation represent?
(1) synthesis
(2) decomposition
(3) single replacement
(4) double replacement
Answer: Option (3) is the correct answer.
Explanation:
When a more reactive element or atom replaces a less reactive atom then this type of reaction is known as single displacement reaction.
In the given reaction, potassium iodide reacts with fluorine and results in the formation of potassium fluoride and iodine.
Here, fluorine being more reactive displaces iodine from potassium iodide.
Therefore, it is a single replacement or displacement reaction.
The given balanced equation represents a single replacement reaction.
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.
Let's consider the following balanced equation.
2 KI + F₂ → 2 KF + I₂
Which type of chemical reaction does this equation represent?
The given balanced equation represents a single replacement reaction.
