Why is calcium chloride an ionic bond

2 answers:

6 0

Answer:Ionic compounds generally form between elements that are metals and elements that are nonmetals. For example, the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl2). In this compound, there are two negative chloride ions for each positive calcium ion.

An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west. It start

galina1969 [7]

Answer:

it moves 25 inches.

Explanation:

the east west bit isn't important, ignore it. if an ant starts at 6 then moves to 19 then we need to subtract 19 from 6, that's 13. then it moves to 7. the difference between 19 and 7 is 12. add that to 13 and you get 25. it's important to remember that there is no such thing as negative distance. if it moved, then it counts.

Within the visible spectrum, our experience of red is associated with ________ waves of light.

kirill115 [55]

Within the visible spectrum, our experience of red is associated with a <u>longer wavelength </u>of light.

<h3>What is the electromagnetic spectrum?</h3>

The electromagnetic spectrum is seen as colors: violet, indigo, blue, green, yellow, orange, and red. Blue light has a very short wavelength, and so produces a higher amount of energy.

In the visible spectrum, the longer wavelengths that we perceive as red are followed by intermediate wavelengths for green and shorter wavelengths for blue and violet.

Our perception of red is connected to a longer wavelength of light within the visible spectrum.

Hence longer wavelength is the correct answer for blanks.

Because blood contains charged ions, moving blood develops a Hall voltage across the diameter of an artery. A large artery with

RoseWind [281]

Answer:

maximum possible potential difference = 1.62 mV

Explanation:

given data

diameter d = 0.75 cm = 0.75 × $10^{-2}$ m

flow speed v = 0.9 m/s

magnetic field B = 0.24 T

to find out

maximum possible potential difference across the diameter

solution

we know that maximum possible potential difference formula is

Vh = Vd× B × d .............................1

put here value in equation 1 we get

maximum possible potential difference = 0.9 × 0.24 × 0.75 × $10^{-2}$

solve we get

maximum possible potential difference = 1.62 × $10^{-3}$

maximum possible potential difference = 1.62 mV

Calculate the magnitude of the electric field at one corner of a square 1.10 m on a side if the other three corners are occupied

natka813 [3]

The direction of magnetic field is south-east and the magnitude is

$23.66$ × $10^{3} N/C$ .

Here, the magnitude of CD and BC will be cancelled, as they both are in the opposite direction and equal to each other.
the magnitude, towards the diagonal AC will result in CP, which is the direction of the electric field.

magnitude of electric field can be defined as :- The force per charge on the test charge is a straight forward way to define the size of the electric field.

To find the magnitude of the electric field use the formula

$E = kq/ r^{2}$
