They end in the suffix -ide. Example: Sodium chloride is NaCl. Cl2 is a chloride molecule.
Physical Changes and Chemical changes are the 2 types of changes. A physical change is a change in the size, shape or state of matter. Ex: Breaking glass, cutting wood, grating cheese, crumpling up paper A chemical change is a change of one substance into new substance(s). Ex: Burning wood, rotting, tarnishing silver, rusting iron
Given Any Two Elements Within A Group, Is The Element With The Larger Atomic Number Likely To Have A Larger Or Smaller Atomic Radius Than The Other Element?
The atomic radius decreases across a period from left to right and increases down in a given group. That means that since the lower the element is in a group, the larger the atomic radius will be. The atoms with the largest atomic radii are located in Group I and are at the bottom of groups.
The larger the mass, the greater the force of gravity if the distance between them didn't change.
Gold usually has one valence electron.
It's a tree often used to make cane fishing poles. Koala bears eat bamboo.
There are many different types. Some stay relatively small like the gold lantana. There's a white and purple version that stay relatively small, but spread out, but they aren't as hardy. There are larger versions that can be tall--like 5 feet tall and spread out a lot that have multi colored blooms.
One thing it carries is oxygen to various parts of the body. Blood also contains iron and hemoglobin.
Saturated-contains the maximum amount of solute dissolved at a given temp.Unsaturated-can dissolve more solute at its current temperatureSupersaturated-has been heated to dissolve more solute than a saturated solution, then is cooled.
A molecular compound is made of 2 nonmetals sharing electrons with each other.
Iron and copper are two different metal elements. Steel is an alloy made by combining 2 or more elements by melting them together. Steel contains iron and carbon and sometimes other elements like manganese or nickel.
All three of them are compounds--not mixtures. However, if you dissolve them in water to make aqueous solutions of them, then all of them would be. If only one of them is dissolved in water, that is the one to choose. Solutions are homogeneous mixtures.
It would depend on the concentration of it. Saline solution for contacts goes in the eyes and saline is salt water (sodium chloride solution.)
The density of a substance is the mass per unit of volume, or the mass divided by the volume. It's sort of like how tightly packed the particles are in one substance. Concentration involves solutions--how much solute is dissolved in a given amount of solvent. You can make a concentrated solution of Kool Aid by … Read more
