Answer:

Building artificial reefs and limiting fishing activity

Explanation:

The only activity that can successfully increase the natural biodiversity of fishes in the area would be building artificial reefs and limiting fishing activities.

The building of artificial reefs would create several microhabitats for fishes to thrive while limiting fishing activities would ensure that the rate of thriving or multiplication of fishes far outweighs the rate fishes are being removed from the area. Both actions will work synergistically to increase the natural biodiversity of fishes in the area.

The introduction of non-native species can have a negative consequence for the area as non-native species have a history of reducing biodiversity by outcompeting the native species and becoming invasive.

Building artificial reefs and increasing fishing activities would be counterproductive. While artificial reefs can increase the thriving of fishes, increasing fishing activities would take away the gains of the artificial reefs.

Eliminating non-native species and encouraging fishing for large predatory fish will disrupt the ecological balance of the area and might have negative effects on biodiversity.

Answer:

The chemistry between you will be instant. Sometimes it may be hard to know if they like you back. Knowing that you can not live without them and that you bump in to each other everywhere you go, is fate at work. You might also just need the courage to ask them out. You never know what will happen if you try. :)

Explanation:

Answer:

"This conversions relies on the fact that a mole of gas at STP has a volume of 22.4 L. It is important to note, however, that if the conditions of the gas are different this conversion will NOT work. Under those conditions you must use the ideal gas law to convert between moles and liters."

Answer:

C. Bromine

Explanation:In ionic bond , the metals looses electron and the non metal gains electron.

In the given options ;

Aluminum (Al)= METAL

Copper (Cu) = METAL

Bromine (Br) = NON METAL

Oxygen (O) = NON METAL

That leaves us with bromine and oxygen.

Oxygen has an electronic configuration of 2,6.(see image).

So oxygen needs to gain two electrons.

Bromine has one valence electron ( see image).

So therefore , Bromine needs to gain one electron as It is in Group VII

Catalysts are molecules that lower the activation energy for a given reaction. The specific term used for biological catalysts is Enzymes.

A catalyst is defined as a substance which increase the rate of the reaction chemical reaction, and lowers the pressure and temperature which are needed to start one, in such a way that it doesn't take participate in the reaction.

Activation energy is the minimum amount of energy which must be needed by the compounds foe the production in a chemical reaction. The activation energy of chemical reaction is mainly measured in joules per mole, kilocalories per mole or in kilojoules per mole.

Enzymes are the chemical catalysts which accelerate the chemical reactions at the physiological temperatures by decreasing their activation energy.

Thus, we concluded that the biological Catalysts that lower the activation energy for a given reaction is Enzymes.

Answer:

Mass = 80.6 g

Explanation:

Given data:

Mass of N₂ consumed = ?

Mass of CaCN₂ formed = 265 g

Solution:

Chemical equation:

CaC₂ + N₂      →       CaCN₂ + C

Number of moles of CaCN₂:

Number of moles = mass/molar mass

Number of moles = 265 g/ 92.11 g/mol

Number of moles = 2.88 mol

Now we will compare the moles of CaCN₂ and N₂.

                               CaCN₂            :            N₂

                                   1                   :              1

                                  2.88              :            2.88

Mass of N₂:

Mass = number of moles × molar mass

Mass = 2.88 mol × 28 g/mol

Mass = 80.6 g

Answer:

B.  An electron from the sodium atom moves to  the fluorine atom forming two ions.

Explanation:

In forming this ionic compound NaF, an electron is transferred from the sodium atom to the fluorine atom and two ions are formed.

A branch of science which deals with the study of chemicals is called chemistry.

The correct answer to the question is B.

The reaction between the acid and base is called a neutralization reaction and forms the salt.

Salt is an ionic compound in which cation and anion joined together to form a compound. In an ionic compound, one element gives electrons to the other element to complete the outer shell and make a bond. In the question, sodium has more electrons and gives them to fluorine.

Hence, the correct option is B that is An electron from the sodium atom moves to  the fluorine atom forming two ions.

Explanation:

Answer:

Wouldn't rust because zinc will lose electrons more readily than iron and will therefore oxidize first.

Explanation:

This process whereby rusting of steel is prevented by coating the steel with a layer of zinc is known as galvanization.

Now, in this process, the steel object will be coated in a thin layer of zinc. This coating will prevent oxygen and water from reaching the underneath metal since the zinc will also act as a sacrificial metal.

Now, Zinc is used because it has a lower reduction potential than iron and thus it will get easily more oxidized than iron. Which means the zinc will lose electrons more readily than iron.

Also, since zinc has a lower reduction potential, it is therefore the more active metal. Thus, even if the zinc coating is scratched and the steel is exposed to moist air, the zinc will still get to oxidize before the iron.

Answer:

0.1988 J/g°C

Explanation:

-Qmetal = Qwater

Q = mc∆T

Where;

Q = amount of heat

m = mass of substance

c = specific heat of substance

∆T = change in temperature

Hence;

-{mc∆T} of metal = {mc∆T} of water

From the information provided in this question, For water; m= 22.0g, ∆T = (24°C-19°C), c = 4.18J/g°C.

For metal; m= 34.0g, ∆T = (24°C-92°C), c = ?

Note that, the final temperature of water and the metal = 24°C

-{34 × c × (24°C-92°C)} = 22 × 4.18 × (24°C-19°C)

-{34 × c × (-68°C)} = 459.8

-{34 × c × -68} = 459.8

-{-2312c} = 459.8

+2312c = 459.8

c = 459.8/2312

c = 0.1988

The specific heat capacity of the metal is 0.1988 J/g°C
