<h2>Let us explain about green house gases</h2>

Explanation:

Green house effect

It can be explained as :

The sun emit radiations that consist of infra red rays , ultra violet rays and visible light .
The infra red rays (responsible for heating ) when come from sun , it travels through atmosphere and reaches earth surface .
On striking the earth surface , it gets reflected and reflected infra red ray has greater wavelength .
Then this reflected rays moves back through atmosphere .
On doing so , they encounter certain gas molecules like carbon dioxide , methane etc .
This gases absorb these rays and do not let them to escape through them .
As a result, they get trapped .
As we have already mention that they cause heating effect , due to this property they raise the temperature of atmosphere leading global warming .

Marrrta [24]

Answer:

0.66 mol

Explanation:

Zero Gauge pressure = 14.7 psi

Pressure read = 173 psi

Actual pressure = 173 psi - 14.7 psi = 158.3 psi

P (psi) = 1/14.696 P(atm)

So, Pressure = 10.77 atm

Given that:

Temperature = 20 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T₁ = (20+ 273.15) K = 298.15 K

V = 1.50 L

Using ideal gas equation as:

$PV=nRT$

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = 0.0821 L atm/ K mol

Applying the equation as:

10.77 atm × 1.50 L = n ×0.0821 L atm/ K mol × 298.15 K

⇒n = 0.66 mol

What weight of sodium formate must be added to 4.00L of 1.00 M formic acid to produce a buffer solution that has a pH of 3.50?

tester [92]

Answer:

156,4 g of sodium formate

Explanation:

The pka of the formic acid is 3,74. Using Henderson-Hasselbalch formula:

pH = pka + log₁₀ [A⁻] / [HA] <em>(1)</em>

Where A⁻ is the conjugate base (Formate) and HA is the formic acid.

4.00L of 1.00M formic acid contain:

4.00L × (1.00mol /L) = 4.00 moles

Replacing these moles, the desired pH and the pka value in (1):

3,50 = 3,74 log₁₀ [A⁻] / 4,00 moles

-0,24 = log₁₀ [A⁻] / 4,00 moles

0,575 = [A⁻] / 4,00 moles

<em>2,30 moles = [A⁻] </em>

That means you need 2,30 moles of formate (Sodium formate), to produce the desired buffer. As the molar mass of sodium formate is 68,01g/mol, the weight of sodium formate that must be added is:

2,30mol×(68,01g/mol) =<em> 156,4 g of sodium formate</em>.

I hope it helps!
