Answer:
Sometimes you just have to get yourself hard to understand what you are really going through and how much you have done and how hard you are.
Explanation:
Tbh not all quotes are easy to express but this one sounds really interesting.
But in my opinion this is the best I could describe
Hope you agree. Let me know :)
2H₂ + O₂ → 2H₂O
mole ratio of O₂ : H₂O is 1 : 2
∴ if moles of O₂ = 16 mol
then moles of H₂O = (16 mol × 2)
= 32 mol
Quantitative data can be counted, measured, and expressed using numbers. Qualitative data is descriptive and conceptual.
The correct answer is a. This is because the pH of a solution is defined as -log10(concentration of H+ ions). An inverse logarithmic scale such as this means that a solution with a lower concentration of H+ ions will have a higher pH than one with a higher concentration. Therefore we know that the pH of the second sample will be higher than the first.
Since the logarithmic scale has the base 10, a change by 1 on the scale is a consequence of multiplication/division of the H+ concentration by a factor of 10. As the scale is inverse, this means that a decrease of concentration by factor 1000 is equivalent to increasing the pH by (1000/10) = 3.
Explanation:
I think the answer is this for a better check mass- mass ratio in stoichiometry lesson
