The mass number of 3 isotopes of magnesium are 24,25,26.what is the mass number of the most abundant isotope of magnesium.​
Anarel [89]

Answer:

24.4 amu or g/mole

Explanation:

24 x 0.790 = 19.0 amu

25 x 0.100 = 2.50 amu

26 x 0.110 = 2.86 amu

(Because of the 19.0, the sig figs go only to the 1/10 decimal place)

19.0 + 2.5 + 2.9 = 24.4 amu or g/mole

According to the graph, if you are in a biome where the annual precipitation is about 300 cm and the average temperature is arou
alina1380 [7]

Answer:

We are in Tropical Rainforests.

Explanation:

Biome is basically an ecological region of earth that has specific type of flora and fauna (plants and animals). Every biome has specific abiotic factors like specific climate, temperature, geology, vegetation, soils and relief.

There are total 8 biomes in the world

  • Desert
  • Grassland
  • Temperate Boreal Forest  
  • Chaparral
  • Tropical Savanna
  • Tropical Rainforest
  • Tundra
  • Temperate Deciduous Forest

Now in our question, we have been given some conditions and are asked to identify the biome. The annual precipitation is about 300 cm and the average temperature is around 25 degrees Celsius.

Now, if we study the characteristics of all these biomes, it is very simple to identify that the biome is Tropical Rainforest.

Important characteristics of Tropical Rainforest:

  • They receive more than 200 cm of rain each year.
  • The temperature of the biome is between 20 degree Celsius and 25 degree Celsius during the whole year.
  • Around 50 percent of the animal specie of the world are found here.

<em>Note: </em><em>You can study the characteristics of world’s other biomes in the link : http://www.physicalgeography.net/fundamentals/9k.html </em>


Hope it helps!  :)
