The major carbon sources (reservoirs that release more carbon than absorbed) are: deforestation and fossil fuels

The major carbon sinks (reservoirs that absorb more carbon than released) are:
soil, oceans and plants.

When scientists calculate the amount of carbon dioxide is returned to the atmosphere vs the released the amount of carbon, a large amount is unaccounted for and the total does not add up. This is why scientists believe there is an undiscovered carbon sink somewhere.

Calculate the molarity of a solution of acetic acid made by dissolving 16.00 mL of glacial acetic acid at 25 ∘C in enough water
Soloha48 [4]

Answer : The molarity of solution is, 1.216 g/mole

Explanation : Given,

Density of acetic acid = 1.049 g/ml  (standard value)

Volume of acetic acid = 16.00 ml

Volume of solution = 230.0 ml

Molar mass of acetic acid CH_3COOH = 2(12)+4(1)+2(16)=60g/mole

First we have to calculate the mass of acetic acid.

Mass=Density\times Volume

Mass=1.049g/ml\times 16ml=16.784g

Now we have to calculate the molarity of solution.

Molarity=\frac{\text{Mass of acetic acid}\times 1000}{\text{Molar mass of acetic acid}\times \text{volume of solution in ml}}

Molarity=\frac{16.784g\times 1000}{60g/mole\times 230ml}

Molarity=1.216g/mole

Therefore, the molarity of solution is, 1.216 g/mole

Consider the titration of 30.0 mL of 0.050 M NH3 with 0.025 M. HCl. Calculate the PH after the following volumes of titrant have
DedPeter [7]

Answer:

pH will always be less than 7

Explanation:

This is because NH3 is a relatively weak base and the resulting Acidic salt on titration might hydrolyse to form a buffer solution

What is the wavelength of a microwave with a frequency of 2450 mhz
JulsSmile [24]

Answer:

See below

Explanation:

The way to calculate this

  speed of light =  wavelength * frequency

   3 x 10 ^8 m/s   =   wavelength * 2450000000 Hz

       wavelength = .12245 meters

                    = 1.2245 x 10^-1  Meters
