PH3, explain why there is a partial positive on hydrogen and partial negative on phosphorus.
Paraphin [41]

Answer:

Phosphorus is more electronegative than hydrogen

Explanation:

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons towards itself thereby making a molecule to be polar. The Pauling scale is the most commonly used to measure electronegativity. Fluorine (the most electronegative element) is assigned a value of 4.0 on the Pauling's scale, and values range down to caesium and francium which are the least electronegative elements.

Electronegativity increases from left to right across the periodic table (across the period) hence, phosphorus is far more electronegative than hydrogen. Being more electronegative than hydrogen, phosphorus attracts the bonding electron pair of the P-H bond closer to itself than hydrogen. Since the electrons of the bond are closer to phosphorus than hydrogen, the phosphorus atom acquires a partial negative charge while the hydrogen atom acquires a partial positive charge.

The process by which DNA becomes mRNA occurs where within the cell?
creativ13 [48]

Answer: Transcription

In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.

According to Frank, what is the “10 second rule"?
Lelechka [254]

Answer:

The first option, aka Opick it up off the gound within 10 seconds, and it's o.k. to eat

Explanation:

The 10 second rule is a rule when you drop foods, but if you get it off the floor under 10 seconds, you can eat it.

Did you know that food picked up under 10 seconds and after 10 seconds has almost the same number of bacterias? The 10 second rule is basically worthless.
