Answer:
2HNO3 +Na2CO3 → CO2 + H2O + 2NaNO3
I'd say that his comb has a static electricity charge. It can either be negative, or positive. Let's just say it's positive, and the water is negatively charged. This means that it will affect the water flow when the two charges meet. I hope this helps! ~Mia
Answer: 3.72 M
Explanation:
Expression for rate law for first order kinetics is given by:
![t=\frac{2.303}{k}\log\frac{a}{a-x}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B2.303%7D%7Bk%7D%5Clog%5Cfrac%7Ba%7D%7Ba-x%7D)
where,
k = rate constant = ![3.66\times 10^{-3}s^{-1}](https://tex.z-dn.net/?f=3.66%5Ctimes%2010%5E%7B-3%7Ds%5E%7B-1%7D)
t = age of sample = 15.0 minutes
a = let initial amount of the reactant = 10.0 M
a - x = amount left after decay process = ?
![15.0\times 60s=\frac{2.303}{3.66\times 10^{-3}}\log\frac{10.0}{(a-x)}](https://tex.z-dn.net/?f=15.0%5Ctimes%2060s%3D%5Cfrac%7B2.303%7D%7B3.66%5Ctimes%2010%5E%7B-3%7D%7D%5Clog%5Cfrac%7B10.0%7D%7B%28a-x%29%7D)
![\log\frac{100}{(a-x)}=1.43](https://tex.z-dn.net/?f=%5Clog%5Cfrac%7B100%7D%7B%28a-x%29%7D%3D1.43)
![\frac{100}{(a-x)}=26.9](https://tex.z-dn.net/?f=%5Cfrac%7B100%7D%7B%28a-x%29%7D%3D26.9)
![(a-x)=3.72M](https://tex.z-dn.net/?f=%28a-x%29%3D3.72M)
The concentration of
in a solution after 15.0 minutes have passed is 3.72 M
PH stands for potential hydrogen.
pH can be accurately tested using acid-based indicators since it is a part of the pH of something itself. (acid and bases) The indicators themselves work when the acidic properties of the indicator begins to dissolve and form ions which gives the color indicating the pH.
Answer:
What is the charge on the barium ion and what is the charge of the hydroxide ion.
Explanation:
To get the correct formula they have to add to zero over all.
