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!  :)

Answer the following questions for H2CrO4:
Sholpan [36]

If this molecule is one half of a buffer, then the formula of the second half of the buffer is M2CrO4 where M is a univalent metal.

<h3>What is a strong acid?</h3>

A weak acid is one that is able to ionize completely in solution. The acid called chromic acid H2CrO4 is not  able to ionize completely in solution.

We know that a buffer is composed of a weak acid and its salt or a weak base and its salt hence if the acid H2CrO4 is present in a buffer then the other half must be  salt of the acid.

If this molecule is one half of a buffer, then the formula of the second half of the buffer is M2CrO4 where M is a univalent metal.

Calculate the radius of a tantalum (ta) atom, given that ta has a bcc crystal structure, a d ensity of 16.6 g/cm3, and an atomic
Sidana [21]

solution:

Ta is BCC, a=\frac{4}{\sqrt{3}r},n=2atoms/cell\\p=16.6gram/cm^3,A=180.9gram/mol\\P=\frac{A\times n}{N_{a}\times v}=\frac{180.9\frac{gram}{mol}\times 2 \frac{atom}{cell}}{6.023\times10^23\frac{atom}{mol}\times(\frac{4}{\sqrt{3}\times r})^3\frac{cm^3}{cell}}\\=16.6\frac{gram}{cm^3}\\r=(\frac{180.9\times2}{16.6\times6.023\times10^23\times(\frac{4}{\sqrt{3}})^3})^\frac{1}{3}\times10^8

If the mass of the products measured 120g what would the mass of the reactants
Ket [755]
It has to be 120g because each and every chemical equation has to satisfy the law of conservation of mass, ie sum of mass of products is always equal to the sum of masses of reactants. If reactants=120g, then products=120g
