How does a salt bridge improve a battery?

Chemistry
1 answer:
OlgaM077 [116]3 years ago
3 0

Answer:

A. It keeps the electrolyte solutions neutral.

Explanation:

The electrons flow from the anode to the cathode and the problem is that the cathode may become too negative. The purpose of the salt bridge is to maintain charge balance because the electrons are moving from one-half cell to the other.

What is the wavelength, in nm, of radiation which has an energy if 3.371 x 10^-19 joules per photon?
mr_godi [17]

Answer:

The correct option is:

D) 589.3 nm

Explanation:

Energy of one photon = 3.371\times10^{-19}J

Energy=\frac{hc}{\lambda}\\\\h=Planck's\:constant=6.626\times10^{-34}J/s\\c=speed\:of\:light=3\times10^{8}m/s\\\lambda=wavelength\:of\:radiation\\\\\lambda=\frac{hc}{Energy}=\frac{6.626\times10^{-34}\times3\times10^{8}}{3.371\times10^{-19}}=5.897\times10^{-7}m=589.7nm\\

Hence, the wavelength (in nm) of radiation is 589.7nm (approximately equal to 589.3nm)

The pH at the equivalence point will be a. less than 7.00 b. equal to 7.00 Allohalineup of a sto quivalence point of a titration
True [87]

Answer: c. greater than 7.00

Explanation: The equivalence point of a titration is when all the base is consumed by the acid. When a strong base and a strong acid react, the medium is neutralized because is produced water and salt (which won't suffer hydrolysis). How water's pH is 7, in this type of titration the pH of the equivalence point will be at pH=7. But on titration of a weak acid with a strong base, the reaction of the equivalence point produces water and the conjugate base of the acid. Because the acid is weak, their conjugate base will be strong and will suffer hydrolysis, producing hydroxyl ions, elevating the pH of the water and making it greater than 7.

What is the SI base unit for length?
sp2606 [1]

The SI base unit for length is meter.

In order to make smaller measurements, you can use the centi-, milli-, micro-, etc. prefixes.

When you want to reference larger measurements, you can use the kilo-, mega-, giga- and prefixes such as those.
