The question is incomplete, the complete question is;

Ideally speaking, bonds tend to form between two particles such that they are separated by a distance where _______ net force is exerted on them, and their overall energy is _________.

A.zero, maximized

B. a negative, minimized

C. a positive, minimized

D. a positive, maximized

E. zero, minimized

F. a negative, maximized

Answer:

E. zero, minimized

Explanation:

Chemical bonding occurs when there is a dynamic equilibrium between the attractive and repulsive forces. This means  that the magnitudes of the attractive and repulsive forces are equal and the net force is zero.

Also, at the point where bonding occurs, the energy of the system is minimum. The point on the potential energy curve that represents the bonding energy is the lowest point on the curve.

Ideally speaking, bonds tend to form between two particles such that they

are separated by a distance where zero net force is exerted on them, and

their overall energy is minimized.

For chemical bonding to occur there must be dynamic equilibrium. This is

formed from  magnitude of the attractive and repulsive forces being equal

which translates to the net force being zero.

The overall energy at the exact point of bonding is at the minimum which is

to allow easy transfer or sharing of electrons in the formation of a compound.

Answer:

Molarity = 0.002 M

Explanation:

Given data:

Mass of calcium chloride = 0.321 g

Volume of water = 1.45 L

Molarity of solution = ?

Solution:

Molarity = number of moles / volume in litter.

We will calculate the number of moles of calcium chloride first.

Number of moles = mass/molar mass

Number of moles = 0.321 g/ 110.98 g/mol

Number of moles = 0.003 mol

Molarity:

Molarity = 0.003 mol / 1.45 L

Molarity = 0.002 M

The atoms and molecules are matter. Therefore, option A and B are correct.

Matter is defined as anything that occupies space and has mass—in other words, the "stuff" of the universe. All matter is composed of substances known as elements, which have distinct chemical and physical properties and cannot be broken down into other substances via ordinary chemical reactions.

Matter is defined as anything that occupies space and has mass. Water and air are examples of matter, whereas feelings and sound are not.

Physical and chemical properties can be used to classify matter. Matter is defined as something that occupies space and has mass. Solid, liquid, and gaseous are the three states of matter. The conversion of a material from one state of matter to another without changing its chemical composition is referred to as a physical transition.

Thus, option A and B are correct.

The temperature : 154.73 K

Given

mass = m = 5 g of Cl2

P = 900 mmHg = 1,18421 atm

V = 0.75 L

Required

Temperature

Solution

mol Cl2 = mass : MW = 5 : 71 = 0.07

Ideal gas law : PV = nRT

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.082 L.atm / mol K  

T = temperature, Kelvin  

T = PV/nR

Input the value :

T = 1.18421 x 0.75 / 0.07 x 0.082

T = 154.73 K

Answer:

Physical change

Explanation:

Dissolution of salt in water is a typical example of physical change and not a chemical change.

In a chemical change new products are formed which are different from the reactants.

In a physical change, the state of matter changes from one form to another.

Dissolving epsom salts in water and observing the crystals that are left behind after the water evaporates is not a chemical change.

Answer:

the change in the system internal energy is 20 J

Explanation:

The computation of the change in the system internal energy is as follows:

Since the volume remains constant so the work done would be zero

Now the change in the internal energy is

= Heat given to system - work done

= 20 J - 0

= 20 J

hence, the change in the system internal energy is 20 J

Explanation:

boiling of water  - Physical changes

curdling of milk   - Chemical changes  

photosynthesis   - Chemical changes

melting of wax​  - Physical changes

A physical change is a change that alters the physical properties of matter particularly the form and state. In many of such cases, the change is easily reversible.

Examples are boiling of water and melting of wax

A chemical change is a change in which a new kind of matter is formed. It is always accompanied by energy changes. The process is not easily reversible.

Examples are curdling of milk and photosynthesis.

Any compound with a pH value between zero to seven is considered acidic, whereas a pH value between seven to fourteen is a base. An acid is called a proton donor, while a base is called a proton acceptor (Kolb, 1978).

examples are:

baking soda is basic (pH = 9.0).

Orange juice is mildly acidic (pH = approximately 3.5)

The environment in your stomach is highly acidic (pH = 1 to 2).
