Explanation:
An alkali is able to "cancel" out an acid. What is the other word for "cancelling out the acid"? * a) neutralise b) overcome c) nullify d) become acidic
Answer:
the correct answers is "neutralize"
Explanation:
When an acid is related to a base or also called an alkali and they reach a pH of 7, this acid will be neutralized or it will be canceled as the question says.
This happens so it reaches an equilibrium between both compounds, where the solution medium where these two compounds are is NEITHER ACID NOR BASIC, that is why it is called NEUTRAL medium.
Whenever you read that the pH of a solution is balanced, a neutralized acid, or a ph7 it means that the solution is NEUTRAL.

Which equation represents fermentation? 1. C2H4 + H2O → CH3CH2OH 2. C2H4 + HCl → CH3CH2Cl 3. C6H12O6 → 2CH3CH2OH + 2CO2 4. 2CH3CHO → C3H5CHO + H2O
Answer:
3. C6H12O6 → 2CH3CH2OH + 2CO2
Explanation:
In fermentation a catabolic process occurs, where an organic substance (C6H12O6) is transformed into a simpler one (CH3CH2OH), through incomplete oxidation, which does not require oxygen. Sugars are transformed into ethyl alcohol and carbon dioxide.
The equation C₆H₁₂O₆ → 2CH₃CH₂OH + 2CO₂ represents fermentation

An aluminum can holds 350 mL of gas at 0 C and 1.0 atm. what is the new volume if the can is heated to 10 C and the pressure inside the can rises to 75 atm?
Answer:
Final volume of the gas is 4.837mL
Explanation:
Initial volume (V1) = 350mL = 0.35L
Initial temperature (T1) = 0°C = (0 + 273.15)k = 273.15k
Initial pressure (P1) = 1.0atm
Final volume (V2) = ?
Final temperature (T2) = 10°C = (10 + 273.15)k = 283.15K
Final pressure (P2) = 75atm
To solve this question, we'll have to use combined gas equation which is the combination of all gas law I.e Charle's laws, Boyle's law, Pressure law etc.
According to combined gas equation,
(P1 × V1) / T1 = (P2 × V2) / T2
Make V2 the subject of formula,
V2 = (P1 × V1 × T2) / (P2 × T1)
V2 = (1.0 × 0.35 × 283.15) / (75 × 273.15)
V2 = 99.1025 / 20,486.25
V2 = 0.004837L
V2 = 4.837mL
The final volume of the gas is 4.837mL
Answer:
4.84mL
Explanation:
Step 1:
Data obtained from the question. This include the following:
Initial volume (V1) = 350mL
Initial temperature (T1) = 0°C
Initial pressure (P1) = 1atm
Final temperature (T2) = 10°C
Final pressure (P2) = 75atm
Final volume (V2) =...?
Step 2:
Conversion of celsius temperature to Kelvin temperature.
This can be achieved by using the formula below:
T(K) = T (°C) + 273
Initial temperature (T1) = 0°C
Initial temperature (T1) = 0°C + 273 = 273K
Final temperature (T2) = 10°C
Final temperature (T2) = 10°C + 273 = 283K
Step 3:
Determination of the new volume.
The new volume can be obtained by using the general gas equation as follow:
P1V1/T1 = P2V2/T2
1 x 350/273 = 75 x V2/283
Cross multiply
273 x 75 x V2 = 1 x 350 x 283
Divide both side by 273 x 75
V2 = (1 x 350 x 283) / (273 x 75)
V2 = 4.84mL
Therefore, the new volume is 4.84mL

Given the following chemical equation at equilibrium: H2(g) + I2(g) ↔2HI(g) + heat. If the temperature is raised, in what direction will the equilibrium shift?
Answer: The reaction will shift in left or backward direction.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle. This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
[tex]H_2(g)+I_2(g)\rightleftharpoons 2HI(g)+heat[/tex]
As the given reaction is exothermic as the heat is released in the reaction. When the temperature is raised , the reaction will shift in a direction where temperature is decreasing and that is the reverse reaction which is endothermic in nature.
Thus the reaction will shift in left or backward direction.
What are the conditions for evaporation?
Answer:
For evaporation you need a warm, preferably humid temperature. The rate of evaporation increases with an increase in temperature. A windy climate is best, as wind helps to remove the evaporated water vapour, and therefore creating a better scope for evaporation to continue. The speed of wind is important for evaporation because the wind pulls in dry air, increasing the rate of evaporation.
Short Answer- Hot and humid temperature, lots of wind speed.
Answer:
Explanation:
1 Evaporation is the phase change of a liquid to a gas. There are three very important requirements for evaporation to take place, 1) available energy, 2) available water, and 3) a vertical moisture gradient. Approximately 600 calories of heat must be added to a gram of water for it to evaporate into the air.
2. Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure. It is a fundamental part of the water cycle and is constantly occurring throughout nature.
3.Water evaporates faster if the temperature is higher, the air is dry, and if there's wind. The same is true outside in the natural environment. Evaporation rates are generally higher in hot, dry and windy climates.

A.It became prey to certain organisms in the river.
B.It lacked adaptations suitable for that particular ecosystem.
C.It had no predators in its new environment.
D.It had few organisms to compete with for resources.
Aquatic invasive species are species such as fish or invertebrate that is absorbed by new aquatic environment that are differ from their own natural environment.
When Aquatic invasive species found themselves in a new environment, at first they will experience a rapid increase in the number of their population this is because of the lack of natural predators in the new aquatic environment. As a result of this they bring about the alteration of food web structure, they take in charge of available food for the native species and compete with them. As a result of this competition involved there is a decrease in the population.
Therefore, the statements that gives plausible reasons for this trend is that became prey to certain organisms in the river.

No, if both parents were left-handed, they would not have to be left-handedwhat is the difference between basis and basic
Answer:
Basis and basic are two different words.
In English, Basis is used as a noun while basic is used as an adjective. Basis term refers as the base or starting point of any discussion.
For example: Bread is a basic ingredient of cake.
On the basis of Mendel's hypothesis.
In chemistry, Basis set is used as a set of functions that represent the electronic wave function in the density-functional theory which forms an algebraic equations that can be easily implemented on a computer.
While Basic term is used for substances that can accept a hydrogen ion (H+) from another substance and have pH above 7. such as sodium.
So, It is not important that both the terms, basis and basic change their English meaning if used in chemistry, they both can be used with English meaning in chemistry as well. Bases and basic, both the terms can be used as either English or Chemistry without affecting the meaning.

2
Explanation:
The compound H2CCH2 has the condensed formula C2H4. The name of the compound is ethene. The compound is unsaturated, that is, it contains multiple bonds. The compound has a formula which fits into the general molecular formulae of alkenes (olefins) which his CnH2n.
Olefins have a double bonds between the carbon atoms. That is , the two carbon atoms in Olefins are connected via a double covalent bond. This now implies that the two carbon atoms in ethene (C2H4) are connected by two covalent bonds in the lewis structure of the molecule as is common for Olefins.
In the Lewis dot structure for [tex]\rm H_2CCH_2[/tex], there is one covalent bond present between the carbon atoms. The correct answer is option c.
A dot structure is a method of depicting an atom's valence electrons by placing dots around the atomic symbol. One valence electron is represented by each dot.
In the Lewis dot structure of [tex]\rm H_2CCH_2[/tex], there is one bond between the carbon atoms. This is because each carbon atom has two electrons in its valence shell, and each hydrogen atom has one electron in its valence shell.
The two carbon atoms share two electrons to form one covalent bond, and each carbon atom also shares one electron with a hydrogen atom to form two additional covalent bonds.
Therefore, the correct answer is option c. There is one bond (covalent bond) between the carbon atoms in the Lewis dot structure for [tex]\rm H_2CCH_2[/tex].
