to produce 265 grams of CaCN2? Express your answer to three significant
figures. The reaction requires grams of N2.
Your answer
I need help PLEAS

Answers

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

A coastal area that once supported a thriving fishing industry is overfished. The number of species found living in the marine ecosystem decreases. Which of these activities is most likely to increase the natural biodiversity in the area?

Answers

Answer:

Building artificial reefs and limiting fishing activity

Explanation:

Building artificial reefs and limiting fishing activity Introducing non-native species to fill unoccupied habitats and banning fishing Building artificial reefs and increasing fishing activity Eliminating non-native species and encouraging fishing for large predatory fish

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.

Explanation:

The different phase transitions that occur in mater are;

1) A phase transition from the solid phase to the liquid phase which occur by heating, represented by the arrow 2 and the process is known as melting

2)  A phase transition from the liquid phase to the gaseous phase which occur by further heating the liquid, represented by the arrow 1 and the process is known as evaporation

3) A phase transition from the gaseous phase to the liquid phase which occur by cooling the hot gas, represented by the arrow 2 and is known as condensation

4) A phase transition from the liquid phase to the solid phase which occur by further cooling the liquid, represented by the arrow 5 and the process is known as freezing

5) A phase transition from the solid phase to the gaseous phase which occur by heating the cold solid, represented by the arrow 3 and the process is known as sublimation

6) A phase transition from the gaseous phase to the solid phase which occur by cooling the gas, represented by the arrow 6

Therefore, the phase transition that represent the the cooling of gaseous water to form liquid outside a bottle left outside is represented by the arrow 2

Answer:

3.75mole

Explanation:

Given parameters:

Mass of the carbon(C) = 45g

Unknown:

Number of moles of carbon  = ?

Solution:

The number of moles of a substance can be found using;

      Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

Molar mass of carbon  = 12g/mol

    Number of moles  = [tex]\frac{45}{12}[/tex]   = 3.75mole

The effect of leaky vaccines on how disease spreads is explained by the “imperfect-vaccine hypothesis”. It holds that, without vaccination, a very virulent virus can get into a population and kill infected hosts (people or animals) very quickly – before they have a chance to spread it. This means that the virus will die out very quickly too, as all potential hosts will be dead or immune to it.
