To a 25.00 mL volumetric flask, a lab technician adds a 0.250 g sample of a weak monoprotic acid, HA , and dilutes to the mark w
Basile [38]

Answer: The number of moles of the weak acid in the solution is 0.00396

Explanation:

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}      

a) {\text{Moles of}KOH=0.0846M\times 0.04683L=0.00396mol

The balanced chemical reaction is:

HA+KOH\rightarrow KA+H_2O  

1 mole of base uses = 1 mole of HA  

0.00396  moles of base use = \frac{1}{1}\times 0.00396=0.00396 moles of HA  

Thus the number of moles of the weak acid in the solution is 0.00396

Arrange the steps in order to describe how photons and carbon dioxide contribute to the warming of earth
adell [148]

Answer:

The steps are arranged in the following order, describing how carbon dioxide and photons  impact the earth's warming.

Explanation:

The sequence is in the following order;

  1. The sun radiated sunlight (visible) photons
  2. Photons from the sun strike the earth and become infrared photons
  3. Earth radiates infrared photons into the atmosphere
  4. CO2 in the atmosphere absorb infrared photons
  5. CO2 in the atmosphere emit infrared photons back towards earth

Carbon dioxide (CO2) molecules can absorb energy from infrared (IR) radiation. Due to vibrations caused by this absorption, the CO2 molecules later release extra energy by emitting another infrared photon.

This ability of CO2 molecules to absorb and re-emit infrared energy is what makes it an effective heat-trapping greenhouse gas.
