Define and explain what an atom is

Answers

Answer 1

Answer: Hi,

Atom is the second smallest form of any matter behind elementary particles. They are not visible to human eye. It consists of protons and neutrons in the atom core and electrons outside its core. All protons, neutrons and electrons are a part of atomic nuclei.

The more neutrons atom haves the bigger the mass of an atom is.

Number of electrons determines which element does atom represent. The more electrons atom haves the heavier element atom represents.

Different elements have different properties.

Hope this helped you understand what atom is better.

Hope this helps.

What best describes charles law

Answers

The statement which best describes Charles law is: A) If volume increases, temperature increases.

What is Charles law?

Charles law states that when the pressure of an ideal gas is kept constant, the volume of a gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles law is given by this formula;

$V\;\alpha \;T\n\nV=kT$

This ultimately implies that, as the volume of an ideal gas increases, its temperature also increases in accordance with Charles law.

A) If volume increases, temperature increases

The law is V/T, meaning the two values are directly proportional, as one increases, the other increases too.

Drug medication are often prescribed on the basis of body mass. The adult dosage of Elixophyllin, a drug used to treat asthma, is 6 mg/kg of body mass. Calculate the dose in milligrams for a 160 lb person.

Answers

Answer:

The dose of Elixophyllin for a person of 160 lb is 436.36 mg.

Explanation:

First you have to go from pounds to kilograms. 160 lb x 1kg/2.2lb = 72.73 kg.

Then you have to multiply the dosage by the body mass in kilograms.

(6 mg/kg) x 72.73 kg ⇒ 436.36 mg.
