For each ionic compound formula, identify the main group to which X belongs: (c) X2SO4.

Chemistry

Zinaida [17]2 years ago
6 0

The answer is group 1A.

In the ionic compound formula X₂SO₄, SO₄ has a -2 charge. Hence to balance this -2 charge of SO₄, X must have a +1 charge.

Group 1A elements form X⁺ type of ions because they are metals. So, they have the tendency to lose electrons.

Hence, X must belong to the 1A group.

Ionic Compounds-

  • Ionic compounds are formed by the electrostatic attraction between the anions and the cations.
  • Cations are positively charged ions that are formed due to the loss of electrons.
  • And the anions are negatively charged ions that are formed due to the gain of electrons.
  • Due to this, they have opposite charges and form bonds known as Ionic Bond.

Determine the net number of sigma bonds, the net number of pi bonds, and the overall bond order for N2+. Use 0.5 to indicate a f
trapecia [35]

Answer:

Net number of sigma bonds = 1

Net number of pi bonds = 2

Overall bond order = 3

Explanation:

Electronic configuration of N2 ia  

1s2 2s2 2p3

There is head to head overlap in pz orbital. Thus, there is one sigma bond

Pi bond is formed whenever there is side wise overlapping. Since both px and py undergoes overlapping to form pi bond, there are two pi bonds

Bond order = 0.5 (bonding electron – antibonding electron)

= 0.5 (8-2) = 0.5*6 = 3

Answer them please i cant figure out what it is
miss Akunina [59]

Answer:

iv. The motion between A & B moves at a further distance than C & D's

v. The cyclist travels 800 meters

vi. It takes approx. 80 seconds

vii. The cyclist's speed is 10 meters per second (m/s)

viii. The cyclist's speed is also 10 meters per second (m/s)

vii. (2) The cyclist's average speed is 10 meters per second (m/s)

Explanation:

Speed is calculated using the formula distance divided by time (d/t)

vii (2) needs further explanation:

Though there is a moment of rest, the cyclist still travels the same speed throughout the entire trip. To check this answer however, you can total the distance and time the cyclist traveled and use speed formula to get 10 meters per second, again.

What happens during a phase change from a solid to a liquid?
JulijaS [17]

Answer:

The particles of the solid vibrate faster and faster. After a while, they can start to move around

Explanation: Solid particles movement are restricted due to the strong force of attraction between the molecules,Solid phase will only change to liquid phase if the forces of attraction holding the molecules together are broken down by heat, when this happens the solid particles movement will become more mobile as the substance is moving from solid phase and liquid phase
