Could a compound have the same properties as its component elements?
Compounds are made of bonding few elements. They could not have same properties as its component elements. They could have completely different properties.
How could the glass refuse be distinguished from the metal refuse?
in waste and recyling
What must every element have different?
Each element has a different number of neutrons.
John Dalton believed that atom could join together form?
John Dalton proposed that elements are made of extremely small particles called atoms. He believed that atoms could join together or "hooked" to form elements.
Could a mixture be made up only elements and no compounds?
Yes that is possible. Mixtures can have two or more elements, two or more compounds, or both. For instance, you could have a mixture of noble gases or a mixture of two different elemental metals. The thing is that the elements have to be stable so that they would not react among themselves and form a compound.
What is Dalton's model of an atom described as?
Dalton's theory was based on the principal that the atoms of different elements that could be distinguished by differences in their weights. In 1803, at the Royal Institution He stated this theory.

When this element combines with other elements it usually gives up its one valence electron?
Could be many different elements
Why were the different media accounts of the Stern Report so different from each other?
Different news outlets could make use of different media elements
How could the glass refuse be distinguished from the metal refuse?
in waste and recyling
What are the similarities between mixtures and compounds?
the similarities between compounds and mixtures are that they are both made up of two or more elements and that they could both be separated and then mixed with different elements to make a new mixture and compound.
How could two points 35 degrees north of the equator- one in North America and the other in China - be distinguished using map coordinates?
Their different longitudes differentiate between them.

How do you generate power through sound?
Sound is caused by vibrations, and (at least experimentally) energy could be derived from the variance in transmitted vibrations.
How many different elements in a grain of sand?
It depends upon the source of the sand. Mostly sand is Silicon and Oxygen, but it could contain iron and other metallic elements.
What must every element have different?
Each element has a different number of neutrons.
Which characteristic could distinguished a crystalline solid from an amorphous solid?
The way it breaks
