What is the name for a substance made of billions of oppositely charged ions<br> joined together?
bija089 [108]

Answer:

Ionic substance

Explanation:

An ionic substance is formed when oppositely charged ions link up to form an infinitely large lattice structure that can only be described in terms of unit cells.

Ionic substances may consist of billions of oppositely charged ions. Ionic substances are hard, have high melting and boiling points and do not conduct electricity in the solid state because the ions are not free in the solid state.

However, in solution or molten state, the substance conducts electricity since the ions which are the charge carriers are now mobile.

When an object is lifted 10 feet off the ground, it gains a certain amount of potential energy. If the same object is lifted 30
Elden [556K]

Answer: 3 times as much the potential energy

Explanation:

Potential energy is the energy possessed by an object by virtue of its position.

P.E=m\times g\times h

m= mass of object

g = acceleration due to gravity

h = height of an object  

When same object with same is lifted from 10 feet to 30 feet. The height has increased 3 times , thus the potential energy will also get 3 times as much.

The PH solution of NH3 of 0.950molar solution is 11.612. find the Kb​
Vaselesa [24]

Answer:

1.8 x 10⁻⁵

Explanation:

 NH3(aq)  +  H2O(l)  ⇄ NH4⁺(aq)  +   OH⁻(aq)

I  0.95                              0                    0

C -x                                 +x                  +x

E 0.95-x                           x                    x

Kb= [NH₄⁺] [OH⁻] / (  NH₃) = x²/ (0.95-x )

P(OH) = 14-PH = 14-11.612 = 2.388

(OH)⁻¹ = 10⁻²°³⁸⁸ = 4.09 x 10⁻³ = x

Kb = (4.09 x 10⁻³)²/ (0.95-4.09 x 10⁻³)

= 1.8 x 10⁻⁵

What are valence electrons (be specific)?
Helen [10]
In chemistry, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
