Answer:
He means Explain the differences between mix and match. Give one example of each.
Explanation:
not sure.. you should eat poptarts
1.34 grams of MgNH4PO4*6H2O
Molar mass= 245.1 grams per mole
Moles of MgNH4PO4*6H2O=
(1.34 grams)(1 mole/245.1 grams fertilizer)=0.0054671563 moles fertilizer
MgNH4PO4*6H2O has 1 mole of Phosphorous, so:
0.0054671563 moles fertilizer(1 mole Phosphorous/1 mole fertilizer)
0.0054671563 moles Phosphorous (30.97 grams/ 1 mole)
=0.1693178295 grams Phosphorous
Answer:
C. Atoms of elements with five to seven valence electrons form anions in order to meet the octet rule.
Explanation:
- Atoms of elements gain or lose electron(s) to obey the octet rule by forming cations or anions.
- Atoms with 1 to 3 valence electrons lose electrons to form cations in order to attain a stable configuration.
- Atoms with 5 to 7 valence electrons gain electron(s) to form anions in order to attain stable configuration.
- However, atoms with 8 valence electrons do not require to gain or lose electrons since they an octet configuration.
- Atoms of metallic elements such as those in group 1 and 2 lose electron(s) to form cations while atoms of non-metallic elements such as halogens require to gain electron(s) to form anions so as to obey the octet rule.
Answer:
it is a gas not a mixture
