Answer:
a car traveling 60 miles per hour
Explanation:
PH and pOH are opposites, so pH can be determined by subtracting pOH from 14
pH = 14 - 7.9 = 6.1
D. Itd be 4+. Hope it helps
Okay.. so I guess this is how it goes:
1. Rainforest
2. Temperate deciduous
3. Marine
4. Taiga
5. Tundra
Pls don't completely rely on it, this is my best guess and it's probably right except with Marine life and temperature deciduous. 70% I feel like it would temperate then marine. But check with urself again. Hope this helped..
Answer:
1) phosphorus and chlorine
type of bond = polar covalent
They share their electrons and due to difference in electronegativities the form polar covalent bond.
2) potassium and oxygen
type of bond = ionic
Due to high difference in electronegativities the form ionic bond.
3) fluorine and fluorine
type of bond = non polar covalent
They share their electrons and due to same electronegativities the form non polar covalent bond.
4) copper and aluminum
type of bond = metallic
copper and aluminum make metallic bond like other metals and mostly helpful in making alloys.
5) carbon and fluorine
type of bond = polar covalent
They share their electrons and due to difference in electronegativities the form polar covalent bond.
6) carbon and hydrogen
type of bond = polar covalent
They share their electrons and due to difference in electronegativities the form polar covalent bond.
7) aluminum and oxygen
type of bond = ionic
Due to high difference in electronegativities the form ionic bond.
8) silver and copper
type of bond = metallic
silver and copper make metallic bond like other metals and mostly helpful in making alloys.
