Answer:
Do you mean Tennessine?
Explanation:
It's in the 7th period, and has the shorthand of Rn. And it's 5 into the row.
Answer:
CoSO₄.7H₂O
Explanation:
Some salts are in its hydrate form to stabilize them. The hydrated form of CoSO₄ is:
CoSO₄.XH₂O
To find the hydration of the COSO₄ you must find the ratio of H₂O and CoSO₄ that is:
0.068921 moles H₂O / 0.0098459 moles CoSO₄ = 7
That means you have 7 moles of water per mol of CoSO₄ and the formula is:
<h3>CoSO₄.7H₂O</h3>
Answer: Particles in all states of matter are in constant motion and this is very rapid at room temperature. A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. ... Individual particles in liquids and gases have no fixed positions and move chaotically.

The given statement is false.
The electrons have both wave and particles like properties. It was postulated by De Broglie that electrons have wave nature and suggested that all the matter exhibit wave characteristics. This concept is called the De Broglie hypothesis.
Like all the elementary particles, the electrons possess the characteristics of both waves and particles, in the sense that they can collide with other particles and be diffracted like light.
