The correct option is C.
A Lewis dot diagram is a representation of the valence electron of  an atom, which uses dot around the symbol of the atom. Chlorine has seven electrons in its outermost shell, these seven electrons are arranged in form of dot around the atom of chlorine. If you count the number of dot given in option C, you will notice that they are seven.

Answer:

C. Cl (w/ 2 dots above and to the left of the C, 1 underneath, and 2 dots to the right of the 1).

Explanation:

Hello,

Electron dot structure is related with the Lewis structure showing the valence electrons for a given element. In this case, the involved element is chlorine, whose symbol is Cl, which is located at the group VIIA, it means that it has seven valence electrons (the number of electrons at its outer shell) around it when expressing the aforesaid structure which is arranged as described on the C. option, this is substantiated via the attached picture showing such arrangement.

Best regards.

When small pieces of manganese oxide were added to a solution of hydrogen peroxide, water and oxygen were produced. Manganese ox
Vikki [24]

Answer: In the given reaction increasing the amount of solution is likely to increase the rate of the reaction.

Explanation:

It is known that more is the number of reactant molecules taking part in a chemical reaction more will be the number of collisions occur. As a result, more will be the rate of chemical reaction.

For example, When hydrogen peroxide dissociates into water and oxygen on addition of manganese oxide then increasing the number of reactants (hydrogen peroxide and manganese oxide) will also lead in the increase in rate of reaction.

Thus, we can conclude that in the given reaction increasing the amount of solution is likely to increase the rate of the reaction.

The structure of carbonic acid, an important component of ocean chemistry, is depicted below. What type of model best describes
BabaBlast [244]

Answer: Option (c) is the correct answer.

Explanation:

A physical model is defined as a model which represents how atoms are bonded together and structure of a molecule.

Physical model shows the three dimensional structure of a molecule. Physical models helps to easily understand and visualize the configuration, single bonds, double bonds and total atoms within a molecule.

Thus, we can conclude that given structure of carbonic acid best describes a physical model.

If excess caso4(s) is mixed with water at 25 ∘c to produce a saturated solution of caso4, what is the equilibrium concentration
Ray Of Light [21]

<em>Answer:</em>

The equlibrium concentration sof Ca+2 ion willl be 4.9×10∧-3 M

<em>Data Given:</em>

              Ksp of CaSO4 = 2.4 × 10∧-5

              CaSO4 ⇔ Ca+2   +  SO4∧-2

<em>Solution:</em>

                Ksp = [Ca+2].[ SO4∧-2]

                 2.4 × 10∧-5 = [x].[x]= x²

                 x =  4.9×10∧-3 M

<em>Result:</em>

  • The conc. of Ca+2 ion is 4.9×10∧-3 M

Which statement about gases is true? A. They are made up of particles that always move very slowly. B. They are made up of parti
rosijanka [135]

Answer: D. They are made up of hard spheres that are in random motion.

Explanation:

A gas is a <u>state of aggregation of matter</u> in which, under certain conditions of temperature and pressure, <u>its molecules interact weakly with each other, without forming molecular bonds</u>, adopting the shape and volume of the container that contains them and tending to separate everything possible because of its <u>high concentration of kinetic energy</u>.

The molecules of a gas are practically <u>free</u> and have the ability to be distributed throughout the space in which they are contained because <u>the gravitational forces and attraction between them are practically negligible</u> compared to the speed at which they move. .

Therefore, gas molecules do not travel specific trajectories or vibrate in a stationary position, instead <u>they move quickly and randomly through the entire space of the container that contains them.</u>
