Answer:
Primary goals were to discover the complete set of human genes and make them accessible for further biological study, and determine the complete study of DNA cells in the human genome.
Explanation:
Answer:
trigonal pyramid
Explanation:
Valence electrons of phosphorus = 5
Valence electrons of hydrogen = 1
The total number of the valence electrons = 5 + 3(1) = 8
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,
<u>The Lewis structure is shown below in the image below.</u>
The central atom , P has 3 bonded pairs of electrons and 1 non bonded.
Number of bond pairs = 3
Number of lone pairs = 1
The formula is 
.
<u>According to VSEPR theory, has trigonal pyramidal shape to minimize the repulsions. </u>
Answer:
Case 1 (energy level): In an atom, an electron jumps from energy level 1 to energy level 3. ... The energy will increase.
Explanation:
Answer:
D
Explanation:
Because the other answers can not to be considered to be chemical properties.
Chemical means that the after the reaction the checal properties have changed in a way that it can no longer be called the same ad befor. In short, it can not be undone.
Burning a match is irriversable, meaning you can never go back to the previous situation because the chemical compounds have changed (dramatically).
Melted ice can be frozen again. Steam (evaporated water) can condensate to water which can be heated and can boil again. The chemical contents remain H2O.
Answer:
all these are physical properties except release of heat so it's probably heat energy given off
