What are the two main gases that make up stars Asvab? Basically, stars are big exploding balls of gas, mostly hydrogen and helium. Our nearest star, the Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb.
What are the two main gases that make up star?
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements.
Which two gases make up the majority of the atmosphere quizlet?
*Nitrogen and oxygen are the main components of the atmosphere by volume. Together these two gases make up approximately 99% of the dry atmosphere.
When sodium atoms form sodium ions they what?
A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged.
Which best carries electric current?
Metals like copper, silver and gold are very good conductors of electricity, that is, electrons may flow freely in those and most other metals because of how electrons are arranged around their nuclei. Other materials, like most plastics and ceramics, glass, rubber and teflon behave in the opposite way.
What two gases make up carbon dioxide?
Carbon dioxide, CO2, is a chemical compound composed of two oxygen atoms and one carbon atom. Carbon dioxide present in our atmosphere as a gas absorbs many infrared wavelengths from the sun.
What are the two main gases that the sun is made of what is the percentage of each of these gases?
The sun is mostly composed of the elements hydrogen (H) and helium (He). By mass the composition of the sun is 92.1% hydrogen and 7.9% helium. Various metals make up less than 0.1% of the mass of the sun.
Which element does not contain any neutrons iron carbon oxygen hydrogen?
Hydrogen is the only element that does not contain any neutrons in its nucleus.
When an aqueous solution containing dissolved mineral matter evaporates why does the mineral matter precipitate instead of evaporating with the water?
5) When an aqueous solution containing dissolved mineral matter evaporates, why does the mineral matter precipitate instead of evaporating with the water? The molecules of mineral are too heavy to be evaporated at those temperature conditions and will remain behind in the solution until the solution becomes saturated.
What is it called when a lobster grows a new claw?
When a Lobster grows a claw to replace one that was lost, the process is called. Regeneration.

What is a type of resistance in an AC transformer circuit?
In other words, in an AC circuit electrical resistance is called “Impedance”.
What kind of current do utility company power lines carry?
Most transmission lines are high-voltage three-phase alternating current (AC), although single phase AC is sometimes used in railway electrification systems.
