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: Option (a) is the correct answer.

Explanation:

When a compound dissolves in a solution and changes into ions then it is able to conduct electricity.

For example, KCl is an ionic compound and when dissolved in a solution then it is able to dissociate into K^{+} and Cl^{-} ions. Hence, it is able to conduct electricity.

Therefore, we can conclude that ionic solutes are considered strong electrolytes because strong electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.

matrenka [14]

Answer:

sensory adaption

Explanation:

Sensory adaption is the phenomenon where the intensity of a stimulus experienced by an organism decreases after a certain amount of exposure to the stimulus. This happens in order for us to pay attention to other stimulus.

When you are driving with the windows down and listening to music you are subjected to a lot of stimuli. Here, most of our attention needs to be on driving. So, our brain drowns all the other unneccessary stimuli like the music.

When you enter the car again where the other stimuli which were present while driving are absent, all your attention is diverted to the music. So, your're ears hurt.

Un pendul cu arc oscileaza cu frecventa de 0,25Hz. Cite oscilatii efectueaza acest pendul timp de 10s?
vodka [1.7K]

Given:

The frequency of the pendulum ( f) = 0.25 Hz.

Total time (t) = 10 s

Concept: Frequency means, the number of oscillation in one second.

Time period is the required time by pendulum to complete one oscillation.

∵  In 1.0 second, number of oscillations = 0.25

∴ In 10.0 second, number of oscillations = (0.25 ×10.0) / 1.0 = 2.5

Hence, the required number of oscillation = 2.5

. Maria walked 1.5 miles south to her house in 0.5 hours. What is her speed in miles per hour?
Simora [160]

1) 3 miles/Hour

The speed is defined as the distance covered divided by the time taken:

v=\frac{d}{t}

where

d = 1.5 mi is the distance

t = 0.5 h is the time taken

Substituting,

v=\frac{1.5}{0.5}=3 mi/h

2) 1.34 m/s south

Velocity, instead, is a vector, so it has both a magnitude and a direction. We have:

d=1.5 mi \cdot 1609 m/mi = 2414 m is the displacement in meters

t=0.5 h \cdot 3600 s/h =1800 s is the time taken in seconds

Substituting,

v=\frac{2414 m}{1800 s}=1.34 m/s

And the direction of the velocity is the same as the displacement, so it is south.

Deduce the relation between kwh and joule define 1 watt​
dimulka [17.4K]

Explanation:

We know that kWh is a commercial unit of energy.

Also, 1 Joule = 1 watt × 1 seconds

1\ kWh=1kW \times 1\ h

Since ,1 h = 3600 s and 1kW = 1000 W

1\ kWh=1000\ W \times 3600\ s\\\\1\ kWh = 36\times 10^5\ W-s\\\\1\ kWh=36\times 10^5\ J

So, the relation is : 1\ kWh=36\times 10^5\ J

1 watt is defined as the power of an appliance when the energy is transferred at a rate of 1 Joule per second.
