Ionic solutes are considered strong electrolytes. What does this mean for the conductivity of the solution?
A) Strong electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
B) Strong electrolytes dissolve and do not dissociate in water providing no charged ions to conduct electricity.
C) Being a strong electrolyte refers the type of bonding and has no bearing on conducting electricity.
D) Strong electrolytes do not dissolve in water and can not conduct electricity.
ANSWER:
A) Strong electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
Answer:
b) 900 W
Explanation:
The breaker trips when the current is equal to 20 A. The power (P) is the ddp (V) multiplied by the current. So, for the electric heater, the current is:
P = V*i
1500 = 120*i
i = 12.5 A
So, to become in 20 A, it's needed 7.5 A, which must come from the hairdryer. Its power must be:
P = 120*7.5
P = 900 W
Well, one of the theories was that Charles darwin proved that theory evolution is real so that one theory.
Answer:
The primary cause of rising SST levels worldwide is climate warming due to excessive amounts of greenhouse gases being released into the atmosphere. Heat from the warming atmosphere raises the temperature of the sea surface. ... Water expands as it warms and the increased volume causes sea level rise.
Explanation:
I think so, sorry if wrong
Answer:
The speed of sound is affected by temperature and humidity. Because it is less dense, sound passes through hot air faster than it passes through cold air. ... The attenuation of sound in air is affected by the relative humidity. Dry air absorbs far more acoustical energy than does moist air.
