A covalent bond is a bond between 2 non metals, they share electrons. Ionic bonding occurs between a metal and a non-metal, and they transfer electrons.

Ionic bonding: a chemical bond formed between two ions with opposite charges. Ionic bonds form when one atom gives up one or more electrons to another atom. These bonds can form between a pair of atoms or between molecules

What are three other elements that have 8 valance electrons.
Rina8888 [55]
8 valence electrons means that the element is stable. When we hear stable, we know the group to look at! Noble gases all have 8 valence electrons making them stable and have a full octet. 

Here are some:-

Krypton
Argon
Neon

If the pH is 3.94 what is the concentration of H
solong [7]

Answer:

If pOH is 3.05, pH is 10.95 or

[H+]=1.122⋅10−11 mol/L

Explanation:

pH=−log(H+)Now, what is H+

if your pH is 10.95 (since pH+pOH=14, your pH=10.95).

(H+)=10 −10.95

(H+)=1.122⋅10 −11

This is your hydrogen ion concentration: [H+]=0.00000000001122  mol/L

If you had 1.00 kg of each kind of hardware, how many boxes of each would you<br> have?
dusya [7]

The number of boxes is calculated by dividing the

total mass of hardware boxes by 1.00 kg

<h3>What is a hardware?</h3>

A hardware is a physical component of a system that can be touched and felt.

Because hardware are physical components, they always have a given mass.

Assuming, several hardware each of mass 1.00 kg is available to be chosen from.

Also, assuming that the sum total of the mass of all the hardware is known.

The number of boxes can be calculated as follows:

  • total mass of hardware/1.00 kg

Therefore, the number of boxes is obtained by dividing the sum of the mass of the boxes by 1.00 kg.

Multiple choice-- please help!
kvasek [131]

The rate law for the reaction : r=k.[A]²

<h3>Further explanation</h3>

Given

Reaction

A ⟶ B + C

Required

The rate law

Solution

The rate law is a chemical equation that shows the relationship between reaction rate and the concentration / pressure of the reactants

For the second-order reaction it can be:

1. the square of the concentration of one reactant.

\tt r=k[A]^2

2. the product of the concentrations of two reactants.

\tt r=k[A][B]

And the reaction should be(for second order) :

2A ⟶ B + C

Thus, for reaction above (reactant consumption rate) :

\tt r=-\dfrac{\Delta A}{2\Delta t}=k[A]^2
