Answer:
19,199,280 grams
Explanation:
0.062502343837894 grams in one mole of oxygen
Of course we can ignore the electron mass, but if there are 16 neutrons, and 16 protons we have the
32
S
isotope, which is approx.
95
%
abundant.
Answer:
[OH⁻] = 0.002 M
Explanation:
<u>The definition of pOH</u> is similar to the definition of pH:
This means that with a <u>given pOH value</u>, the calculation of [OH⁻] is a matter of algebra:
To remove the logarithm we increase 10 by the power of the pOH:
=[OH⁻]
Answer:
B
Explanation:
The last 2 answers can immediately be cancelled out as they're not combustion of ethanol, combustion in this context is not a reversable reaction so cannot be referenced in this way.
The answer is determined to be B just by simply counting the numbers of each of the elements on the reactants (left) side and the products (right) side and ensuring they're the same
In A on the reactants side there is 2C 6H 3O and on the products side there is 1C 3O and 2H its not equal so it is not correct
In B on the reactants side there is 2C 6H 7O and on the products side there is 2C 6H 7O its equal so this answer is correct
