Answer:
The area of the block is 150 cm
Explanation:
An element is a substance that can not be broken into simpler parts by chemical means. Elements are made up of atoms. A molecule is the smallest particle of an element or a compound that has the same properties as the element or the compound. A molecule is made up of two or more atoms . A substance may be an element and a molecule. In this case the answer is, H2 (hydrogen gas) which is a molecule with two atoms of hydrogen and an element.
Valence election configuration is the electrons in the shell that equal to 8. it what forms chemcial bonds. Electron configuration is distribution of elections of an atom.
Answer:
ionic, they would make an ion
Explanation:
Answer:
we will except an increase in the polarity of the system and this will cause the Non-polar spot to be near the solvent front, while the polar spot will run at an approximate speed of 0.5 Rf
Explanation:
when we run a TLC plate in a 50/50 mixture of hexanes and ethyl acetate we will except an increase in the polarity of the system and this will cause the Non-polar spot to be near the solvent front, while the polar spot will run at an approximate speed of 0.5 Rf
The speed of the polar spot depends largely on the level of polarity, an increase in the polarity will see both spots of Neat hexane run when we run a TLC plate in a 50/50 mixture of hexanes and ethyl acetate
