Answer:

Ionic bonding

Explanation:

Ionic bonding:-

This type of bonding is formed when there is a complete transfer of electrons from one element to another element. In this bonding one element is always a metal and another is a non-metal.

For example, Calcium iodide

Calcium is the element of second group and forth period. The electronic configuration of Calcium is - 2, 8, 8, 2 or $1s^22s^22p^63s^23p^64s^2$

There are 2 valence electrons of Calcium.

Iodine is the element of seventeenth group and fifth period. The electronic configuration of Iodine is - 2, 8, 18, 18, 7 or $[Kr]4d^{10}5s^25p^5$

There are 7 valence electrons of iodine.

Calcium iodide, $CaI_2$ is formed when 2 valence electrons of calcium are loosed and they are gained by 2 atoms of iodine.

erma4kov [3.2K]

Answer: 1: kinetic energy and velocity are at zero when the magnets are held apart, and both increases rapidly when they are released and move together. Energy stored in the magnetic field decreases.

2: The energy stored in the system is converted to kinetic, thermal, and sound energy.

3: The energy stored in the magnetic field does not change.

4: Some of the energy stored is converted into kinetic and thermal energy.

5: Two small repelling magnets hold each other in place.

Just took the quiz all are correct! I hope this helps you! :)

A rural, forested area receives a lot of rain in a short amount of time. What

lakkis [162]

Answer: A. If the surface aquifer has a high water table

Explanation:

The water table refers to the water level underground. If it is high, it means that the water underground is close to the surface such that if a well was dug, it would not need to be dug too far for water to be seen.

When heavy rain falls, flooding is avoided if the water is either able to run off efficiently or if the ground is able to absorb the water. When the water table is high, it means that the ground will not be able to absorb much because the water is already close to the surface which means that should heavy rain fall, there will most likely be a flood.

A sound wave travels in air toward the surface of a freshwater lake and enters into the water. The frequency of the sound does n

Rashid [163]

Answer:

wavelength in the water = 1.311 m

Explanation:

givendata

wavelength of the sound in air = 5.67 m

temperature = 20°C

solution

as we know velocity c in air = 343.3 m/s and velocityˇc in water= 1484m/s

and we take wavelength = w

and

wavelength=velocity ÷ frequency .................1a

as we know here that In air and in water if the frequency not change then there wavelength depend on speed of sound in air and water

wavelength of sound in water = w in air × c in water ÷ c in air

wavelength in the water in water = 5.67 × 343.2 ÷ 1484

wavelength in the water = 1.311 m
