Answer:

When electromagnetic radiations enter earth surface , it passes through several layers of our atmosphere in meantime some raditions get reflected back and some reaches to us .

Answer:

Hey!

The electromagnetic radiation the Earth recieves form the sun is a mixture of Infrared, Visible and Ultraviolet (UV)...

As these different wavelengths of Electromagnetic radiation approaches the Earth, these are absorbed by different parts of the atmosphere or reach the surface (where Humans are present)...

A layer of OZONE absorbs UV rays...

Visible light is of course not absorbed by the Atmosphere and reaches the surface of the Earth (This is what we see as daylight)

The layer of GREENHOUSE GASES (Carbon-Dioxide, Methane) absorbs and reflects the Infrared rays (aka HEAT) and sometime re-emitted back into space...

C3H8+3O2 = 3CO2+4H2O what is the enthalpy combustion
dezoksy [38]

Answer:

\Delta H_{comb}=2043.85kJ/mol

Explanation:

Hello there!

In this case, according to the given chemical reaction, it possible for us to set up the expression for the calculation of the enthalpy change as shown below:

\Delta H_r=-\Delta H_{comb}=3\Delta _fH_{CO_2}+4\Delta _fH_{H_2O}-\Delta _fH_{C_3H_8}-3\Delta _fH_{O_2}

Thus, given the values of the enthalpies of formation on the attached file, we obtain:-\Delta H_{comb}=3(-393.5kJ/mol)+4(-241.8kJ/mol)-(-103.85kJ/mol)-3(0kJ/mol)\\\\-\Delta H_{comb}=-2043.85kJ/mol\\\\\Delta H_{comb}=2043.85kJ/mol

Best regards!

A gas balloon has a volume of 80.0 mL at 300K, and a pressure of 50.0 kPa. If the pressure changes to 80 kPa and the temperature
fomenos

Answer:  The new volume is 53.3 ml

Explanation:

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas =  50.0 kPa

P_2 = final pressure of gas = 80.0 kPa

V_1 = initial volume of gas = 80.0 ml

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 300K

T_2 = final temperature of gas = 320K

Now put all the given values in the above equation, we get:

\frac{50.0\times 80.0}{300}=\frac{80.0\times V_2}{320}

V_2=53.3ml

The new volume is 53.3 ml

Is is true or false that ocean currents affect the climate I certain regions on earth​
vfiekz [6]

True. Coastal regions are affected if it is warm currents over the ocean it make for a higher temperature over the land, if it's a colder current over the ocean it makes for temperatures to drop over land. This happens when the wind blows in from the sea.

What are Rhodium isotopes used for?
Lina20 [59]

Answer:

Rhodium is used to make electrical contacts, as jewelry and in catalytic converters, but is most frequently used as an alloying agent in other materials, such as platinum and palladium. These alloys are used to make such things as furnace coils, electrodes for aircraft spark plugs and laboratory crucibles.
