Explain how temperature and amount of precipitation can affect the type of plants and animals found in the grassland biome?

Chemistry

MArishka [77]3 years ago

Temperature grasslands have hot summers and cold winters. Summer temperatures can be well over 100 degrees Fahrenheit, while winter temperatures can be as low as -40 degrees Fahrenheit. They typically have between 10 and 35 inches of precipitation a year, much of it occurring in the late spring and early summer. As climate conditions shift geographically so will the distributions of many plants and animals. The relatively flat terrain of grasslands increases vulnerability to climate change impacts, because habitats and species must migrate long distances to compensate for temperature shift.

If two gases are present in a container, the total pressure in the container is equal to
qwelly [4]

Answer: sum of the pressure of the two gases present.

Explanation:

According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

p_{total}=p_A+p_B

For example if there are there are two gases hydrogen and oxygen with individual pressure of 30 and 20 atm each. Then the total pressure in the container will be:

p_{total}=p_{H_2}+p_{O_2}

Thus p_{total|=30atm+20atm

p_{total}=50atm

Thus if two gases are present in a container, the total pressure in the container is equal to sum of the pressure of the two gases present.

How many atoms and ions does lithium sulfite have?
Serhud [2]

Answer:

Hence the<u> ions per mole</u> are:

Li^{+}= 2 ions

SO_{3}^{2-}(aq)= 1 ions

In one mole of Li2SO3 , the number of the atoms are

N_{a}=6.022\times 10^{23}

Explanation:

The formula of  lithium sulfite is Li2SO3.

Li_{2}SO_{3}

It contain Li+ and SO3(2-) ions.This can be represented by :

Li_{2}SO_{3}(s)\rightarrow 2Li^{+}(aq) +SO_{3}^{2-}(aq)

Hence one mole of Li2SO3 will give 2 Li+ ions and 1 SO3 (2-) ion.

Hence the<u> ions per mole</u> are:

Li^{+}= 2 ions

SO_{3}^{2-}(aq)= 1 ions

Number of atoms in  lithium sulfite depends upon the<u> mass of the Li2SO3 present</u> .

Li2SO3 = 93.94 g/mole

This mass is equal to 1 mole of Li2SO3

Now<u> 1 mole</u> of any substance contain Na atoms . This is known as Avogadro Number.

N_{a}=6.022\times 10^{23}

Hence , if 1 mole of Li2SO3 is present then it contains Na atoms

If other then 1 mole present then number of atoms are calculated by:

Number\ of\ Atoms=Moles\times (N_{a})

Here n = number of moles

if the mass of the compound is given then first calculate the number of moles.

Moles=\frac{mass}{Molar\ mass}
