Answer:

Explanation:

According to this question, each model of molecules in the options contains spheres of different colors and sizes representing different types of atoms. The atoms of the same element are the spheres of same color and size while atoms of different element are of different color or size.

Therefore, the model showing a molecule of a substance that is made up of three elements is model D because it is made up of three distinct spheres representing atoms of each element.

- The red sphere is the atom of the first element

- The big dark sphere is the atom of the second element

- The small white sphere is the atom of the third element

Electricity generated from any source comes with its own advantages and disadvantages. So, no source of energy for generating el

irakobra [83]

Answer:

Wind energy

An ideal source of energy needs to be reliable, cost effective, safe and must lead to almost zero adverse environmental impact.

Wind energy is energy obtained from air moving at high velocity. This energy is harvested using windmills which convert mechanical energy to electrical energy.

Wind is inexpensive because it occurs naturally. However, a large expanse of land is required in order to mount sufficient number of windmills that will generate enough electrical energy for practical purposes.

This method of electricity generation is safe and does not lead to any environmental hazard unlike the burning of fossil fuels, use of nuclear energy or loss of habitat due to hydroelectric power generation.

An irreversible reaction is one that:

bazaltina [42]

Answer:

(d) has an extremely large equilibrium constant.

Explanation:

Hello,

Considering a generic chemical reaction:

$aA+bB cC+dD$

The equilibrium constant is defined as:

$K=\frac{[C]^c_{eq}[D]^d_{eq}}{[A]^a_{eq}[B]^b_{eq}} \\$

Now, an irreversible chemical reaction is a reaction in which the reagents are converted into products with no chance of coming back, so, considering the previous chemical reaction, the concentration of both A and B tends to be zero, so an extremely large equilibrium constant is gotten.

Best regards.

Name the following ionic compounds that contain transition metals. Use the periodic table provided

Goryan [66]

The correct name of the compound CuCl is copper I chloride.

An ionic compound is formed two atoms when one loose electrons and the other atoms gains those electrons. Ionic bonds are actually an ion pair, a pair of oppositely charged ions held together by electrostatic interaction. Transition metals are elements with incompletely filled d orbitals. Copper is a transition element.

The compound CuCl is named copper I chloride. We can see that the copper is in the +1 oxidation state in this compound hence the name.
