Answer:
Explanation:
(3 pts) A 5.00 gram sample of an oxide of lead PbxOy contains 4.33 g of lead. Determine the
simplest formula for the compound.
Answer:
The correct answer is b polar covalent
Explanation:
When two atoms joined by covalent bond has difference in their electronegativities at that time polarity arise.
When the electronegativity difference is low such as 1.3 then the polar bond formed by the two atoms are called polar covalent bond.For example H2O
on the other hand polar bond formed by two atoms having high difference in their electronegativities is called ionic bond.For example NaCl.
Answer:
They are releasing less carbon dioxide into the air.
Carbon dioxide is what causes global warming and greenhouse gases, etc.
