Answer:
The substance that remained on the filter paper is Al(OH).
Explanation:
- Filter paper is the substance that is used in laboratory to separate the solid objects. It doesn't filter aqueous and gaseous products.
- So in our experiment the product formed is aluminum hydroxide Al(OH) and sodium chloride (NaCl).
- Between two products, sodium chloride is in aqueous form as indicated in the question. So it wont remain in the filter paper.
- Hence aluminum hydroxide being only solid product remains on the filter paper.
it is water energy :) this is easy
Answer:
Whether the mixture can be separated
Answer:
<em>first </em><em>example</em><em> </em><em>is</em><em>. </em><em>Air </em><em> </em><em>it </em><em>is </em><em>mixture </em><em>of </em><em>many </em>
<em>gases </em><em> </em>
<em>it's </em><em>us </em><em> </em><em>it </em><em>keeps </em><em>us </em><em>alive </em><em> </em><em>and </em><em>many </em><em>more </em><em>uses</em>
<em>second </em><em>example</em><em> </em><em>is </em><em>water </em><em>is </em><em>also </em><em>a </em><em>mixture</em><em> </em>
<em>made </em><em>up </em><em>of </em><em>carbon </em><em>and </em><em>hydrogen</em><em> </em>
<em>and </em><em>its uses </em><em>is </em><em>to </em><em>fulfill</em><em> </em><em>our </em><em>needs </em>
<em>hope </em><em>it </em><em>helps</em>
Each orbit surrounding an atom is allowed A LIMITED NUMBER OF ELECTRONS.
The number of orbit that an atom has is determined by its atomic number, the higher the atomic number the higher the number of orbit in the atom and each orbit has different energy level. Each orbit can only take fixed number of electron. The first shell can only take two electrons while the subsequent shells can only take eight electrons. When an orbit has taken the highest number of electron possible, the remaining electrons are moved to the next shell.
