A theory of chemical combination, first stated by John Dalton in 1803. It involves the following postulates: (1) Elements consist of indivisible small particles (atoms). (2) All atoms of the same element are identical; different elements have different types of atom. (3) Atoms can neither be created nor destroyed.

Answer:

<h3><u>The </u><u>Postulates of Dalton's Atomic Theor</u>y<u>:</u></h3>
  • All matter is made of very tiny particles called atoms.
  • Atoms are indivisible particles which cannot be created or destroyed in a chemical reaction.
  • Atoms of given element are identical in mass and chemical properties.
  • Atoms of different elements have different masses and chemical properties.
  • Atom combine in the ratio of small whole numbers to form compounds.
  • The relative number and kinds of atoms are constant in a given compound.

What is a metal and a non metal​
Mrac [35]

Answer:

I assume you mean as in elements

A metal "A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable or ductile." (wiki)

a non-metal "In chemistry, a nonmetal is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity." (wiki)

Heating a carboxylic acid with a primary amine forms water along with what organic product? OA) A secondary amide OB) A primary
Bezzdna [24]

Answer:

A) secondary amide

Explanation:

When carboxylic acid reacts with a primary amine, a condensation reaction takes place with the elimination of a water molecule .

For example, ethanol reacts with methylamine which is a primary amine gives N-Methylacetamide and a water molecule as:

CH_3COOH+NH_2CH_3\rightarrow CH_3-CONH-CH_3+H_2O

The bond formed which is

  O

   ||

-- C  ---NH ---

is known as secondary amide group as only one hydrogen is attached to nitrogen atom in the amide bond.

Need help please it must be right thank u
vova2212 [387]

Answer:

13. c) Net

14. a) Gravity

15. d) Watt

16. b) the speed will suddenly decrease.

Explanation:

13. The <u>net </u> force is combination of all individual forces.

14. When we sit on the chair , then <u>gravitational force</u> acts on our body due to our mass.

F = mg

here, F = force due to gravity , g = acceleration due to gravity  and m= mass of the body

15.Power : It is the force acting per unit area .It is discovered by James Watt

Power =\frac{force}{area}

Power =\frac{N}{m^{2}}

Its unit is Nm^{-2} .In honor of the Scientist , its unit is Watt.

Watt = Nm^{-2}

16. When the parachute first opens , the <u>speed of the skydiver suddenly decreases</u> because of the resistance offered by the air particles.(For more details look at the figure attached)

17. Transfer of momentum from one object to other is t<u>he law of conservation of momentum</u><u> </u>(NOT ENERGY).So the answer is<u> </u><u>False</u>

<u> Law of Conservation of Momentum : </u> Total momentum of a system is conserved if no external force attack on it. Momentum can neither be created nor destroyed but transferred from one form to other.
