Any photos below 7 is known as acidic, the lower the pH the more acidic the solution I believe.
C. Cells
Cells make up organs, which make up organisms, which make up populations
<span>1) Which of
the following is a possible formula unit? PbO - Li2B - Al2Pb3
- ClO
The correct answer is PbO which is Lead(II) oxide – also known as Lead Monoxide
– which is an inorganic compound. It is an Amphoteric oxide which can be found,
in modern use, in industrial glass, ceramics, or computer components, due to
its crystal structure. </span>

<span>2) What is
the formula of a compound formed between iodine (I) and calcium (Ca)?
Calcium will always give two electrons. but iodine can receive only one. Therefore
two atoms of iodine react with one atom of calcium to give CaI2. Their bond is
an ionic bond.
Ca 2+ + 2I 1- --> CaI2</span>

<span>3) What is
the resulting formula unit when strontium (Sr) and phosphorus (P) bond?
Strontium (Sr) wants to lose two (2) electrons, and phosphorus (P) wants to
gain three (3). By using the criss-cross method, if you flip the 2 and 3 to the
opposite elements, you will end up with the formula Sr3P2.</span>
Answer:
1. Always put hair up at all time Because if you don't you can accidently burn your hair and you don't want to get chemicals on it.
