PH = -log [H3O+]
4.15 = -log [H3O+]
[H3O+] = 10^(-4.15)
[H3O+]= 7.08 × 10^-5

The Concentration can be calculated as 
 pH = -log [H3O+]
4.15= -log [H3O+]
[H3O+] = 10^(-4.15)
[H3O+]= 7.08 × 10^-5

1 - causes the molecules of the object or surface it strikes to vibrate faster, increasing its temperature.

2-carbon dioxide, methane, nitrous oxide, and water vapor it has to be one of these 3

3-The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.”

4- because of the fossil fuels that people are burning for energy.

5- due to human activities

Calcule la densidad del hidrógeno H2 en g/L a 327 mm Hg y 48ºc
tankabanditka [31]
<h3>The density of H₂ = 0.033 g/L</h3><h3>Further explanation</h3>

In general, the gas equation can be written  

\large {\boxed {\bold {PV = nRT}}}

where  

P = pressure, atm , N/m²

V = volume, liter  

n = number of moles  

R = gas constant = 0.082 l.atm / mol K (P= atm, v= liter),or 8,314 J/mol K (P=Pa or N/m², v= m³)

T = temperature, Kelvin  

n = N / No  

n = mole  

No = Avogadro number (6.02.10²³)  

n = m / MW

m = mass  

MW = molecular weight

For density , can be formulated :

\tt \rho=\dfrac{P\times MW}{R\times T}

P = 327 mmHg = 0,430263 atm

R = 0.082 L.atm / mol K

T = 48 ºC = 321.15 K

MW of H₂ =  2.015 g/mol

The density :

\rho=\dfrac{0,430263\times 2.015 }{0.082\times 321.15}\\\\\rho=0.033~g/L
