Methane and carbon dioxide gas are two harmful greenhouse gases. identify two sources of these gases and discuss what society can do to reduce their impact on the environment.

Two major source of methane are –  

a)Burning of fossil fuels

b)Natural wetlands

Two major source of carbon dioxide gas –  

a)Release from ocean  

b)Respiration

Measures taken by society to reduce the impact of carbon dioxide and methane

a)   Plantation

b)  Reduction of green house gases

c) Sustainable practice

Explanation:

Two major source of methane are –  

a)Burning of fossil fuels

b)Natural wetlands

Two major source of carbon dioxide gas –  

a)Release from ocean  

b)Respiration

Measures taken by society to reduce the impact of carbon dioxide and methane

a)Plantation – This will help in reducing the adverse impacts of CO2 and methane gas.  

b)Reduction of green house gases - Reducing the use of machine , equipment’s and mode of transportation that further intensifies the problem of green house gases.  

c) Sustainable Practice - Sustainable technologies for energy  and goods production must be promoted.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
