Fluorite is inorganic solid and can be defined by its chemical formula. Thus option D is correct.

Chemical formula is defined as a chemical elements numbers and symbols are used to provide information about the chemical quantities of atoms that make up a certain chemical compound or molecule.

It is also defined as any of numerous statements of a chemical compound's content or structure.

There are mainly three types of chemical formulas.

Thus, fluorite is inorganic solid and can be defined by its chemical formula. Thus option D is correct.

Answer:

A. Some forces cause objects around us to move,

C. Every force can be identified as one of the fundamental forces,

D. Force is the ability to change motion and transfer matter,

Explanation:

Force basically is defined as pull or push on a body. Forces are known to cause the change in motion of a body as the amount of force applied is attenuated.

Answer:

The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition. Although we call them physical "reactions," no reaction is actually occurring. In order for a reaction to take place, there must be a change in the elemental composition of the substance in question. Thus, we shall simply refer to physical "reactions" as physical changes from now on.

Introduction

Physical changes are limited to changes that result in a difference in display without changing the composition. Some common changes (but not limited to) are:

Texture

Color

Temperature

Shape

Change of State (Boiling Point and Melting Point are significant factors in determining this change.)

Physical properties include many other aspects of a substance. The following are (but not limited to) physical properties.

Luster

Malleability

Ability to be drawn into a thin wire

Density

Viscosity

Solubility

Mass

Volume

Any change in these physical properties is referred to as a physical change. For further information, please refer to Properties of Matter.

Chemical changes, on the other hand, are quite different. A chemical change occurs when the substance's composition is changed. When bonds are broken and new ones are formed a chemical change occurs. The following are indicators of chemical changes:

Change in Temperature

Change in Color

Noticeable Odor (after reaction has begun)

Formation of a Precipitate

Formation of Bubbles

Note: When two or more reactants are mixed and a change in temperature, color, etc. is noticed, a chemical reaction is probably occurring. These are not definite indicators; a chemical reaction may not be occurring. A change in color is not always a chemical change. If one were to change the color of a substance in a non-chemical reaction scenario, such as painting a car, the change is physical and not chemical. This is because the composition of the car has not changed. Proceed with caution.

Explanation:

The number of moles of glucose can be found by using the formula

[tex]n = \frac{m}{M} \\ [/tex]

where

n is the number of moles

M is the molar mass

m is the mass of the substance

First we must find the molar mass of glucose

[tex]M(C) = 12 , \: \: \: M( H_2) = 1 \: \: , \: \: M(O_2) = 16 \\ [/tex]

The molar mass of glucose is

[tex]M(C_6H_{12}O_6) = (12 \times 6) + 12 + (16 \times 6) \\ = 72 + 12 + 96 \\ \\ = 180 \: \: g/mol \: \: \: [/tex]

mass = 640 g

So we have

[tex]n = \frac{640}{180} = \frac{64}{18} = \frac{32}{9} \\ = 3.5555..[/tex]

Answer:

its b beacuse different things have different mass

The iron has become part of a A. compound with the sulfate, which must be separated through chemical methods.

Iron (II) sulfate is also referred to as ferrous sulfate is a reducing agent. The hydrates form is used for the treatment of iron deficiency.

It should be noted that a chemical change is involved in the formation of iron (II) sulfate. It can't be separated by physical means and isn't reversible.

In this case, iron (II) sulfate will be separated by chemical methods.

Iron sulfate is a compound which can be separated through chemical methods.

Iron is present in a compound form with the sulfate, which must be separated through chemical methods because both iron and sulfate reacts with each other through making of chemical bonds with each other. Those elements that combine with each other chemically at a fix ratio can be separated from each other through chemical methods.

While on the other hand, in mixture substances combine with each other physically so they can be separated from each other through physical methods so we can conclude that iron sulfate is a compound which can be separated through chemical methods.

Answer:

New volume V2 = 120.4 ml

Explanation:

Given:

Pressure P1 = 1.12 atm

New pressure P2 = 1.12[1+0.25] = 1.4 atm

Old volume V1 = 150.5 ml

Find:

New volume V2

Computation:

P1V1 = P2V2

(1.12)(150.5) = (1.4)(V2)

V2 = 120.4 ml

New volume V2 = 120.4 ml
