A balloon filled with helium rises when youlet it go. A balloon filled with carbon dioxide
sinks. Explain the difference.

Answers

Answer 1

Answer: A balloon filled with helium rises when you
let it go while a balloon filled with carbon dioxide
sinks. This is because the gases inside the balloons have different densities. Both gases have different densities where one is lighter than air (Helium) and the other is heavier than air (CO2).

A match-head is flammable, but you have to get it up to its ignition temperature first.

A diamond is flammable, but its ignition temperature is astronomical and
totally out of sight.

Diamonds are not flammable, but are combustible, when a diamond burns there is no ash because diamonds are pure carbon and when burned it is turned into carbon dioxide.

Is sodium element a metal nonmetal or metalloid

Answers

Sodium Na is a soft, low-density member of the alkali metal family. The element sodium is a very delicate silvery-white.

Sodium makes up 2.8 percent of the Earth's crust and is the most prevalent alkali metal and sixth most plentiful element on the planet.

A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Typically, metals are malleable and ductile.

Ionic linkages mix metals with non-metals, whereas metallic connections happen between metal atoms. The metallic bonding joins metal atoms.

The mass number of Fe2+ is 56. How many neutrons are there in a single Fe2+ atom?

Answers

The mass of an atom comes from the protons and neutrons that are found in the nucleus. The number of protons is the atomic number of an element. To find the number of neutrons, subtract the atomic number from the mass of an atom. If the mass number of Fe2+ is 56. The atomic number is 26, so 56 – 26 equals 30 neutrons.

Explanation:

Water can dissolve other substances. Which factor best contributes to this property of water?A. Water is made up of ionic bonds.
B. Water has weak intermolecular forces.
C. Water is denser than most substances.
D. Water particles are not fixed in place.

Answers

Water is known to be theuniversal solvent because it can mostly dissolve most of the substances. Thereason behind its solvability is the bonding of intermolecular forces of attraction.The answer is letter B. Out of the many bondings between molecules, the bondthat governs water is H bonding or hydrogen bonding. Water is composed mostlyof two atoms of hydrogen one atom of oxygen. Both the hydrogen and oxygen arepolar elements and hydrogen is bounded with a high electronegativity oxygen atom.
