Answer:
Correct answer is a. Ag(s) reacts spontaneously with 1M H+(aq).
Explanation:
A charasteristic of metals is that they lose easily electrons, cations tends to gain electrons to react and anions tends to lose or share electrons to react.
If you want to make a chemical reaction you must to mix a reagent that tends to lose electrons with other that tends to gain them.
In the statement (a) we have a metal that loses electrons and a cation that can obtain them, so is the right answer.
note that the other optios have :
b) Metal with metal cation, not react beacause left a medium of reaction.
c) Both loses electrons
d) Both tends to gain electrons.
Answer:concentration
Explanation:
In the first, the particles are much more concentrated, or close together, than in the second, where the particles are much more sparse.
Hello!
Order of magnitude of a measure is an estimate of the base power 10 closest to a given measure.
The scientific notation (N) of 0.000000000333 (x), being (number of decimal places) y, knowing that the scientific notation according to the rule of scientific notation, before the comma can only have the numbers 1 to 9, let's see:
![N = x*10^y](https://tex.z-dn.net/?f=%20N%20%3D%20x%2A10%5Ey%20)
![N = 0.000000000333*10^y](https://tex.z-dn.net/?f=%20N%20%3D%200.000000000333%2A10%5Ey%20)
![\boxed{\boxed{N = 3.33*10^{-10}}}\end{array}}\qquad\checkmark](https://tex.z-dn.net/?f=%20%5Cboxed%7B%5Cboxed%7BN%20%3D%203.33%2A10%5E%7B-10%7D%7D%7D%5Cend%7Barray%7D%7D%5Cqquad%5Ccheckmark%20)
note: Moved 10 decimal places to the right negatively
I Hope this helps, greetings ... DexteR! =)
The answer is 308 K.
The formula is C + 273.15 = K
this meaning the formula for this problem would be 35 + 273.15 = 308.15.
Out of all the option choices that would be rounded to 308K.
