Same: Both are natural disasters. Both are becoming more common to due climate change.
Different: Floods are an excess amount of water whereas droughts are a lack of water for a prolonged period of time. Floods are more common in coastal areas whereas droughts are most common in the Midwest and South.
Answer:
2.60 M
Explanation:
M1V1=M2V2
Where
M1 = ?
V1 = 20.9 mL
M2 = 2.548 M
V2 = 21.39 mL
(?)(20.9 mL) = (2.548 M)(21.39 mL)
------------------ -----------------------------
(20.9 mL) (20.9 mL)
? = (54.50)/(20.9) = 2.60 M
(Side Note: the mL cancel each other out to leave M units only)
Answer:
56 %
Explanation:
The percent dissociation of a weak acid can be defined as:
Moles of weak acid that produced H₃O⁺ species / Total number of weak acid moles * 100%
We are given all the required data to <u>calculate the percent dissociation</u>:
0.42 mol / 0.75 mol * 100 % = 56 %
The percent dissociation is 56%.
Electrons are not a part of the mass number,
Tin has 50 Electrons
50 Protons, and 69 Neutrons are in a Tin Atom
Take a look at this and let me know if you've any doubts further!
