Hello!
Data:
Molar Mass of H2CO3 (carbonic acid)
H = 2*1 = 2 amu
C = 1*12 = 12 amu
O = 3*16 = 48 amu
------------------------
Molar Mass of H2CO3 = 2 + 12 + 48 = 62 g/mol
Now, since the Molarity and ionization constant has been supplied, we will find the degree of ionization, let us see:
M (molarity) = 0.01 M (Mol/L) →
Use: Ka (ionization constant) =
Now, we will calculate the amount of Hydronium [H3O+] in carbonic acid (H2CO3), multiply the acid molarity by the degree of ionization, we will have:
And finally, we will use the data found and put in the logarithmic equation of the PH, thus:
Data:
apply the data to formula
Note:. The pH <7, then we have an acidic solution (weak acid).
Now, let's find pOH by the following formula:
I Hope this helps, greetings ... DexteR! =)
Less than that of nitrogen and oxygen remember cnof "see noff" . this is the order of electronegativity carbon is less than nitrogen which is less than oxygen which is less than fluorine.
Answe
I hope this is useful! :)
Explanation:
We use the equation:
Mass = Number of moles * Molecular or atomic mass
Since the number of moles is 1 ("one mole of carbon-12 atoms") and the atomic mass of carbon-12 atoms is 12, hence the mass would be 12 grams. Note that the unit grams (g) is used here, as it is the SI unit for mass measurement.
Number of particles in 1 mole = 6.023 × 1023
Mass of 1 electron = 9.10938 × 10-28 gm
Mass of 1 mole of electrons = 6.023 × 1023 × 9.10938 × 10-28 = 5.486 × 10 -4
Mass of 1 proton = 1.67262 × 10 -24 gm
Mass of 1 mole of protons = 6.023 × 1023 × 1.67262 × 10 -24 gm = 1.007 gm
Mass of 1 neutron = 1.67493 × 10-24 gm
Mass of 1 mole of neutron = 1.67493 × 10-24 × 6.023 × 1023 = 1.008 gm
Answer:
the main cause of climate change is burning fossil fuels such as oil, gas, and coal. When burnt, fossil fuels release carbon dioxide into the air, causing the planet to heat up.
