Answer: Please see explanation for answer

Explanation:Matching the  descriptions to the correct element listed gives

Element Group Name Group No Metal/ Nonmetal/ Metalloid Description

Neon    Noble gases       18           Non metal Colorless, tasteless, and        odorless gas, unreactive, nonconductive.

Bromine      Halogens   17          Non metal Not found as a free element (uncombined) in nature, reddish-brown liquid that vaporizes readily at room temperature to a red gas with a strong disagreeable odor.

Beryllium       Alklaline earth metal  2    Metal  Silvery-white, ductile, malleable, conductive solid with a high melting point for this type of element

Platinum     Platimum group metals  10   Metal      Silvery white, relatively soft, low density, conductive solid that is not found as a free element in nature but commonly found combined in alloys with copper or nickel

Potassium   Alkali Metals   1   Metal  Soft, easily cut with a knife to expose a silvery surface that rapidly oxidizes in air; never found uncombined in nature

Silicon    Carbon family     1`4  Metalloid   Metallic luster and grayish solid, very common in rocks and gemstones such as amethyst and opal, semiconductor

Sulfur   Calcogens      16  Non metal  Pale yellow, odorless, brittle solid at room temperature, nonconductor

Stella [2.4K]
<span>Answer: option D) Conditions over the oceans change slowly because water takes more time than land to gain or lose heat.

This is because water has a high heat capacity meaning that, with the same amount of heat, it will change its temperature less than what substances with lower heat capacities do.

How is the energy of the universe conserved during the combustion of gasoline in a car engine?
Marianna [84]
In a car driven by a gasoline combustion engine, heat energy is quickly converted into kinetic energy which results in the motion of the car.

According to the law of the conservation of energy, energy cannot be destroyed or created. It is can only be transformed from one form to another.

A chemical reaction can be reversed if?
Wittaler [7]

Chemical reaction can be reversed if the energy of the reactants is less than the activation energy threshold.

<h3>What is a reversible reaction?</h3>

A reversible reaction is a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously.

<h3>Conditions for reversible reaction</h3>

In equilibrium reaction, the activation energy of the forward reaction is more than that of backward reaction which causes bond breakage of the reactants.

Activation energy = (Threshold energy) - (Internal energy of the reactants)

Thus, a chemical reaction can be reversed if the energy of the reactants is less than the activation energy threshold.
