What exactly is the project about ?????
The list of 4 things can increase the rate of a reaction is:
surface area of a solid reactant.
concentration or pressure of a reactant.
temperature.
nature of the reactants.
presence/absence of a catalyst.
Hope this helped :)
Have a great day
Due to erosion, the soil is taken away from one place to another.This decreases the fertility of the land,.. it also is a cause for floods. Due to erosion, the vegetation is destroyed and nothing can be cultivated for a higher yield in the rough sandy land . Due to weathering of rocks, there is an advantage. The advantage is that the weathering of volcanic rocks give rise to Black Soil by which special crops like cotton,tobacco and sugarcane can be cultivated. Due to weathering, a hilly range may turn into a plain land after thousands of years.
Carbon atom has two isotopes
relative abundance of one isotope = 98.89% = 98.89 / 100 = 0.9889
As this isotopes have 6 neutrons and 6 protons, and there sum is equal to the mass of that isotope = 6 + 6 = 12amu
And other isotope have relative abundance = 1.11% = 1.11/100 = 0.0111
And mass of that isotope = 7 neutrons + 6 protons = 13amu
Now, average atomic mass of carbon = (0.9889 x 12) + (0.0111 x 13) =11.8668 + 0.1443 = 12.0111 = 12.0 = 12
<h3>Answer:</h3>
10 Atoms
<h3>Explanation:</h3>
The structure of said compound is sketched according to guide lines provided in statement and is attached below.
Hydrogen Bond Interactions:
Hydrogen Bond Interactions are those interactions which are formed between a partial positive hydrogen atom bonded directly to most electronegative atom (i.e. F, O and N) of one molecule and the partial negative most electronegative atom of another molecule.
In given structure we are having seven most electronegative oxygen atoms (labelled red) and three partial positive hydrogen atoms (labelled blue) directly attached to most electronegative atom (i.e. oxygen atoms).
Therefore, the oxygen atoms will make hydrogen bonds with water's hydrogen atoms and the partial positive hydrogen atoms will make hydrogen bonds with water's oxygen atoms respectively.
